Abstract:

We studied the competition between Bradyrhizobium japonicum and Rhizobium fredii isolates for nodulation of soybean (Glycine max L. Merrill) cultivars Williams and Ai Jiao Zao grown in three different soils in pots. Two of the soils were from People's Republic of China, one from a soybean field in Honghu with no history of Rhizobium inoculation, and one from a rice field in Wuhan with no history of soybean cultivation. The Honghu soil contained B. japonicum and R. fredii (log total number g−1 = 5.82 ± 0.58); whereas the Wuhan soil only contained B. japonicum (log total number g−1 = 2.80 ± 0.52). Inoculation did not result in a significant increase in nodule number on plants in either soil. Uninoculated plants of both cultivars harbored only R. fredii in the Honghu soil and only B. japonicum in the Wuhan soil. Even when B. japonicum were inoculated into the Honghu soil, R. fredii occupied the majority of the nodules on both cultivars. In the Wuhan soil, B. japonicum serogroups USDA110 and USDA136b (= CB1809) occupied the majority of the nodules except when an isolate of R. fredii from the soybean soil was added in high numbers. In a Hawaiian soil devoid of B. japanicum or R. fredii, when soybeans were inoculated with isolates of both species, most of the nodules were formed by B. japonicum. The R. fredii isolate could form up to 20% of nodules in this soil, but only on the Ai Jia Zao cultivar. In the Wuhan but not the Hawaiian soil, peat pelleting of seeds with equal numbers of two B. japonicum and one R. fredii isolates increased nodule occupancy by B. japonicum USDA136b serogroup significantly as compared with when the same isolates were inoculated into the soil. The results reported here highlight the critical importance of being indigenous to the competitive success of B. japonicum and R. fredii in nodulation of their soybean host.

Abstract:

Sinorhizobium fredii HH103-Rifr, a broad host range rhizobial strain, induces nitrogen-fixing nodules in Lotus burttii but ineffective nodules in L. japonicus. Confocal microscopy studies showed that Mesorhizobium loti MAFF303099 and S. fredii HH103-Rifr invade L. burttii roots through infection threads or epidermal cracks, respectively. Infection threads in root hairs were not observed in L. burttii plants inoculated with S. fredii HH103-Rifr. A S. fredii HH103-Rifr nodA mutant failed to nodulate L. burttii, demonstrating that Nod factors are strictly necessary for this crack-entry mode, and a noeL mutant was also severely impaired in L. burttii nodulation, indicating that the presence of fucosyl residues in the Nod factor is symbiotically relevant. However, significant symbiotic impacts due to the absence of methylation or to acetylation of the fucosyl residue were not detected. In contrast S. fredii HH103-Rifr mutants showing lipopolysaccharide alterations had reduced symbiotic capacity, while mutants affected in production of either exopolysaccharides, capsular polysaccharides, or both were not impaired in nodulation. Mutants unable to produce cyclic glucans and purine or pyrimidine auxotrophic mutants formed ineffective nodules with L. burttii. Flagellin-dependent bacterial mobility was not required for crack infection, since HH103-Rifr fla mutants nodulated L. burttii. None of the S. fredii HH103-Rifr surface-polysaccharide mutants gained effective nodulation with L. japonicus.

Abstract:

The bacterium Sinorhizobium meliloti Rm2011 forms N2-fixing root nodules on alfalfa and other leguminous plants. The pSymB chromid contains a 110-kb region (the ETR region) showing high synteny to a chromosomally located region in Sinorhizobium fredii NGR234 and related rhizobia. We recently introduced the ETR region from S. fredii NGR234 into the S. meliloti chromosome. Here, we report that, unexpectedly, the S. fredii NGR234 ETR region did not complement deletion of the S. meliloti ETR region in symbiosis with Medicago sativa. This phenotype was due to the bacA gene of NGR234 not being functionally interchangeable with the S. meliloti bacA gene during M. sativa symbiosis. Further analysis revealed that, whereas bacA genes from S. fredii or Rhizobium leguminosarum bv. viciae 3841 failed to complement the Fix− phenotype of a S. meliloti bacA mutant with M. sativa, they allowed for further developmental progression prior to a loss of viability. In contrast, with Melilotus alba, bacA from S. fredii and R. leguminosarum supported N2 fixation by a S. meliloti bacA mutant. Additionally, the S. meliloti bacA gene can support N2 fixation of a R. leguminosarum bacA mutant during symbiosis with Pisum sativum. A phylogeny of BacA proteins illustrated that S. meliloti BacA has rapidly diverged from most rhizobia and has converged toward the sequence of pathogenic genera Brucella and Escherichia. These data suggest that the S. meliloti BacA has evolved toward a specific interaction with Medicago and highlights the limitations of using a single model system for the study of complex biological topics.

Abstract:

To achieve effective symbiosis with legume, rhizobia should fine-tune their background regulation network in addition to activating key genes involved in nodulation (nod) and nitrogen fixation (nif). Here, we report that an ancestral zinc finger regulator, MucR1, other than its paralog, MucR2, carrying a frameshift mutation, is essential for supporting nitrogen fixation of Sinorhizobium fredii CCBAU45436 within soybean nodules. In contrast to the chromosomal mucR1, mucR2 is located on symbiosis plasmid, indicating its horizontal transfer potential. A MucR2 homolog lacking the frameshift mutation, such as the one from S. fredii NGR234, can complement phenotypic defects of the mucR1 mutant of CCBAU45436. RNA-seq analysis revealed that the MucR1 regulon of CCBAU45436 within nodules exhibits significant difference compared with that of free-living cells. MucR1 is required for active expression of transporters for phosphate, zinc, and elements essential for nitrogenase activity (iron, molybdenum, and sulfur) in nodules but is dispensable for transcription of key genes (nif/fix) involved in nitrogen fixation. Further reverse genetics suggests that S. fredii uses high-affinity transporters to meet the demand for zinc and phosphate within nodules. These findings, together with the horizontal transfer potential of the mucR homolog, imply an intriguing evolutionary role of this ancestral regulator in supporting nitrogen fixation.

Abstract:

Many different Rhizobium strains produce melanin (Mel+) when grown on solid media supplemented with L-tyrosine. The composition of the media and the culture conditions are of great importance for pigment production. Previous reports showed that some Rhizobium leguminosarum biovar phaseoli strains that produce the pigment in complete solid media (TY) failed to produce the pigment in minimal media (SY) supplemented with L-tyrosine or in TY liquid media. In this paper we have investigated different R. fredii, R. meliloti, R. etli and R. leguminosarum bv. trifolii and phaseoli strains (all of them Mel+ in solid media) for their ability to produce the pigment in liquid media. All Rhizobium species tested, except Rhizobium etli, were Mel+ in liquid media and in all cases the pigment yielded maximum absorption peaks at 280 and 315 nm. Melanin production by other bacteria (such as Vibrio, Streptomyces or Azospirillum) is enhanced by the presence of amino acids other that tyrosine. In this paper we show that the addition of L-methionine, which is not a precursor of rhizobial melanins, stimulated pigment production by Rhizobium cultures supplemented with L-tyrosine. The role of melanin production by Rhizobium strains is unclear. One hypothesis is that the Rhizobium tyrosinase, a bifunctional copper-containing enzyme that is essential for melanin biosynthesis, could detoxify polyphenolic compounds which might accumulate in senescing nodules. We show here that R. etli and R. fredii bacteroids produced melanin, which supports the idea that bacteroids contain the enzyme tyrosinase. Previous reports showed that, in R. leguminosarum bv. phaseoli strain 8002, the expression of the tyrosinase gene (melA) is dependent on the presence of nifA, a regulatory gene that is located in the symbiotic plasmid. However, transfer of R. leguminosarum bv. phaseoli melA gene to pSym-cured derivatives of R. leguminosarum bv. trifolii and viciae, R. fredii and Rhizobium sp. (Hedysarum) produced Mel+ transconjugants. DNA-hybridisation experiments showed that the pSym-cured strains did not contain any copy of nifA. Therefore, in contrast to the results reported on R. leguminosarum bv. phaseoli strain 8002, the expression of the melA gene in other rhizobia is not nifA-dependent. Key words: Rhizobium, melanin.

Abstract:

The rhizobium–legume symbiotic system is crucial for nitrogen cycle balance in agriculture. Hydrogen sulfide (H2S), a gaseous signaling molecule, may regulate various physiological processes in plants. However, whether H2S has regulatory effect in this symbiotic system remains unknown. Herein, we investigated the possible role of H2S in the symbiosis between soybean (Glycine max) and rhizobium (Sinorhizobium fredii). Our results demonstrated that an exogenous H2S donor (sodium hydrosulfide [NaHS]) treatment promoted soybean growth, nodulation, and nitrogenase (Nase) activity. Western blotting analysis revealed that the abundance of Nase component nifH was increased by NaHS treatment in nodules. Quantitative real-time polymerase chain reaction data showed that NaHS treatment upregulated the expressions of symbiosis-related genes nodA, nodC, and nodD of S. fredii. In addition, expression of soybean nodulation marker genes, including early nodulin 40 (GmENOD40), ERF required for nodulation (GmERN), nodulation signaling pathway 2b (GmNSP2b), and nodulation inception genes (GmNIN1a, GmNIN2a, and GmNIN2b), were upregulated. Moreover, the expressions of glutamate synthase (GmGOGAT), asparagine synthase (GmAS), nitrite reductase (GmNiR), ammonia transporter (GmSAT1), leghemoglobin (GmLb), and nifH involved in nitrogen metabolism were upregulated in NaHS-treated soybean roots and nodules. Together, our results suggested that H2S may act as a positive signaling molecule in the soybean–rhizobia symbiotic system and enhance the system’s nitrogen fixation ability.

Abstract:

Sinorhizobium fredii HH103 is a rhizobial strain showing a broad host range of nodulation. In addition to the induction of bacterial nodulation genes, transition from a free-living to a symbiotic state requires complex genetic expression changes with the participation of global regulators. We have analyzed the role of the zinc-finger transcriptional regulator MucR1 from S. fredii HH103 under both free-living conditions and symbiosis with two HH103 host plants, Glycine max and Lotus burttii. Inactivation of HH103 mucR1 led to a severe decrease in exopolysaccharide (EPS) biosynthesis but enhanced production of external cyclic glucans (CG). This mutant also showed increased cell aggregation capacity as well as a drastic reduction in nitrogen-fixation capacity with G. max and L. burttii. However, in these two legumes, the number of nodules induced by the mucR1 mutant was significantly increased and decreased, respectively, with respect to the wild-type strain, indicating that MucR1 can differently affect nodulation depending on the host plant. RNA-Seq analysis carried out in the absence and the presence of flavonoids showed that MucR1 controls the expression of hundreds of genes (including some related to EPS production and CG transport), some of them being related to the nod regulon.

Abstract:

Particulate enzyme preparations from Rhizobium and Bradyrhizobium synthesize β-glucans when incubated with uridine diphosphate glucose (UDP-glucose) and a divalent cation. Synthesis of β-1,2-linked glucans in Rhizobium fredii involves the product of the ndvB gene, a 319-kDa membrane protein, which is labeled with [14C]glucose from UDP-[14C]glucose as previously demonstrated in Rhizobium meliloti and Agrobacterium sp. Bradyrhizobium japonicum synthesize β-1,3- and β-1,6-linked glucans of a lower molecular weight than those synthesized by R. meliloti. In comparative experiments, no evidence was found for a protein-bound intermediate in B. japonicum. The ndvB gene of R. fredii was mobilized to B. japonicum and the gene was expressed, as evidenced by appearance of a large membrane protein (ca. 319 kDa) which was labeled with UDP-[14C]glucose in vitro. Key words: soybean, nitrogen fixation, β-glucan, Bradyrhizobium, Rhizobium.

Abstract:

ABSTRACT We have cloned and sequenced three genes from Rhizobium meliloti (Sinorhizobium meliloti) that are involved in sulfate activation for cysteine biosynthesis. Two of the genes display homology to the Escherichia coli cysDN genes, which code for an ATP sulfurylase (EC 2.7.7.4 ). The third gene has homology to the E. coli cysH gene, a 3′-phosphoadenosine-5′-phosphosulfate (PAPS) reductase (EC 1.8.99.4 ), but has greater homology to a set of genes found in Arabidopsis thaliana that encode an adenosine-5′-phosphosulfate (APS) reductase. In order to determine the specificity of the R. meliloti reductase, the R. meliloti cysH homolog was histidine tagged and purified, and its specificity was assayed in vitro. Like the A. thaliana reductases, the histidine-tagged R. meliloti cysH gene product appears to favor APS over PAPS as a substrate, with a Km for APS of 3 to 4 μM but a Km for PAPS of >100 μM. In order to determine whether this preference for APS is unique to R. meliloti among members of the familyRhizobiaceae or is more widespread, cell extracts fromR. leguminosarum, Rhizobium sp. strain NGR234,Rhizobium fredii (Sinorhizobium fredii), andAgrobacterium tumefaciens were assayed for APS or PAPS reductase activity. Cell extracts from all four species also preferentially reduce APS over PAPS.

Abstract:

Rhizobium fredii produces nitrogen-fixing (Fix+) nodules on primitive soybean lines, but most strains do not form such structures with the small number of agronomically advanced lines that have been tested. We systematically evaluated the ability of R. fredii USDA257 to produce Fix+ nodules on 197 soybean lines available in the midwestern United States. Thirty-four of 197 such lines were Fix+. The frequency of this response was positively correlated with increasing maturity group. The acetylene-reduction rate of one advanced cultivar, Davis, was greater than that of the primitive cultivar, Peking. Our data indicate that the capacity to nodulate effectively with USDA257 is widespread in contemporary North American soybean lines.Key words: Acetylene-reduction, nodulation, Rhizobium, soybean

Abstract:

ABSTRACT Rhizobium etli type strain CFN42 contains six plasmids. We analyzed the distribution of genetic markers from some of these plasmids in bean-nodulating strains belonging to different species (Rhizobium etli, Rhizobium gallicum, Rhizobium giardinii, Rhizobium leguminosarum, and Sinorhizobium fredii). Our results indicate that independent of geographic origin, R. etli strains usually share not only the pSym plasmid but also other plasmids containing symbiosis-related genes, with a similar organization. In contrast, strains belonging to other bean-nodulating species seem to have acquired only the pSym plasmid from R. etli.

Full text

Abstract:

A constitutively expressed chromosomal gene, nolC, regulates the ability of Rhizobium fredii strain USDA257 to nodulate certain agronomically improved soybean cultivars. Other advanced cultivars, as well as unimproved varieties such as 'Peking', form nitrogen-fixing nodules with parental strain USDA257 and with nolC mutants. We have used 257DH512, a derivative of USDA257 that contains a nolC-lacZ fusion, to directly measure strain competition for nodule occupancy. Seedlings of the soybean cultivar 'Peking' were inoculated with mixtures containing various ratios of 257DH512 and R. fredii USDA208; nodules were harvested 14 days later and stained histochemically with X-gal, a chromogenic substrate for the β-galactosidase product of lacZ. We were able to stain and evaluate batches of nearly 500 nodules in just 4 h, without the use of expensive equipment. Under the conditions of these experiments, USDA208 was considerably more competitive than 257DH512, even when it had been present in the inoculum at a numerical disadvantage. We suggest that gene fusions can be used to greatly simplify the assessment of nodulation competitiveness in rhizobia. Key words: competition, nolC-lacZ fusion, soybean – Rhizobium fredii, nodule occupancy.

Abstract:

The structure of a polysaccharide from Sinorhizobium fredii HH103 has been determined. This polysaccharide was isolated by following the protocol for lipopolysaccharide extraction. On the basis of monosaccharide analysis, methylation analysis, fast atom bombardment MS, matrix-assisted laser desorption ionization MS, electron-impact high-resolution MS, one-dimensional 1H-NMR and 13C-NMR and two-dimensional NMR experiments, the structure was shown to consist of a homopolymer of a 3:1 mixture of 5-acetamido-3,5,7,9-tetradeoxy-7-[(R)- and (S)-3-hydroxybutyramido]-L-glycero-L-manno-nonulosonic acid. The sugar residues are attached via a glycosidic linkage to the OH group of the 3-hydroxybutyramido substituent and thus the monomers are linked via both glycosidic and amidic linkages. In contrast with the Sinorhizobium K-antigens previously reported, which are composed of a disaccharide repeating unit, the K-antigen polysacharide of S. fredii HH103 is a homopolysaccharide.

Abstract:

Nodulation, plant growth and seed yield of the supernodulating mutant Rico 32M2-BS and its parent, cv. OAC Rico (Phaseolus vulgaris L.) are described in relation to supply of combined N and inoculation with Rhizobium leguminosarum bv. phaseoli and R. fredii. Combined N depressed nodule numbers more severely in the mutant than in its parent line, OAC Rico, at the first sample 14 d after seeding, but at 35 d, combined N increased nodule numbers in both the mutant and OAC Rico, and increased nodule mass in the mutant. In the absence of N, AR per plant increased between 14 and 35 d but AR per gram nodule weight declined. In the +N treatment, AR per plant and per gram nodule was greatest at 28 d, but in other samples AR of the +N treatments tended to be lower than in −N treatments. Plant growth of both the mutant and OAC Rico was stimulated by combined N. Both the mutant and OAC Rico nodulated well and effectively with three pure strains of R. leguminosarum bv. phaseoli and with indigenous soil strains. They both nodulated ineffectively with three strains of R. fredii, but the mutant plants still expressed their supernodulating characteristic. In the field test, plant growth of the mutant and OAC Rico was similar at the three levels of N fertilizer. Nodule dry weight was greater in the mutant than in OAC Rico; nitrogen depressed nodule dry weight in both lines. Seed yield of OAC Rico was 1.5 times that of the mutant.Key words: Combined N, common bean, nitrogen fixation, nodulation mutants, Phaseolus, Rhizobium, supernodulation

In Rhizobium etli CFN42, both the symbiotic plasmid (pd) and plasmid b (pb) are required for effective bean nodulation. This is due to the presence on pb of a region (lpsβ) involved in lipopolysaccharide (LPS) biosynthesis. We report here the genetic array and functional features of this plasmid-borne region. The sequence analysis of a 3,595-bp fragment revealed the presence of a transcriptional unit integrated by two open reading frames (lpsβ1 and lpsβ2) essential for LPS biosynthesis and symbiosis. The lpsβ1 encodes a putative 193 amino acid polypeptide that shows strong homology with glucosyl-1P and galactosyl-1P transferases. The deduced amino acid sequence of the protein encoded by lpsβ2 was very similar to that of proteins involved in surface polysaccharide biosynthesis, such as Pseudomonas aeruginosa WpbM, Bordetella pertussis BplL, and Yersinia enterocolitica TrsG. DNA sequences homologous to lpsβ1 and lpsβ2 of R. etli CFN42 were consistently found in functionally equivalent plasmids of R. etli, R. leguminosarum bv. viciae, and R. leguminosarum bv. trifolii strains, but not in R. meliloti, R. loti, R. tropici, R. fredii, Bradyrhizobium, Azorhizobium, and Agrobacterium tumefaciens. Even though Rhizobium and Agrobacterium do not share lpsβ sequences, their presence is required for crown-gall tumor induction by R. etli transconjugants carrying the Ti plasmid.

Abstract:

ABSTRACT The role of glycine betaine and choline in osmoprotection of various Rhizobium, Sinorhizobium,Mesorhizobium, Agrobacterium, andBradyrhizobium reference strains which display a large variation in salt tolerance was investigated. When externally provided, both compounds enhanced the growth of Rhizobium tropici,Sinorhizobium meliloti, Sinorhizobium fredii,Rhizobium galegae, Agrobacterium tumefaciens,Mesorhizobium loti, and Mesorhizobium huakuii, demonstrating their utilization as osmoprotectants. However, both compounds were inefficient for the most salt-sensitive strains, such asRhizobium leguminosarum (all biovars), Agrobacterium rhizogenes, Rhizobium etli, and Bradyrhizobium japonicum. Except for B. japonicum, all strains exhibit transport activity for glycine betaine and choline. When the medium osmolarity was raised, choline uptake activity was inhibited, whereas glycine betaine uptake was either increased in R. leguminosarum and S. meliloti or, more surprisingly, reduced in R. tropici, S. fredii, and M. loti. The transport of glycine betaine was increased by growing the cells in the presence of the substrate. With the exception ofB. japonicum, all strains were able to use glycine betaine and choline as sole carbon and nitrogen sources. This catabolic function, reported for only a few soil bacteria, could increase competitiveness of rhizobial species in the rhizosphere. Choline dehydrogenase and betaine-aldehyde dehydrogenase activities were present in the cells of all strains with the exception of M. huakuii and B. japonicum. The main physiological role of glycine betaine in the family Rhizobiaceae seems to be as an energy source, while its contribution to osmoprotection is restricted to certain strains.

Abstract:

The article presents the problem of the confirmation of treatises between Commonwealth and elector Frederic William of Brandenburg concluded in 1657 during the negotiations in Oliva monastery in 1660 con�cerning that peace of the war which was waged in northern Europe from 1655. The Brandenburg tried to include these both sides treatises in conclusions of the peace of Oliva to reach guarantees of general peace what could bring to elector the recognition of his release from the Fief in Duchy of Prussia and confirmation of his political independence in this territory. The Swedes didn’t want to agree with this conception because they levelled charges for all the treatises concluded during the war that have been made, in their mind, against them. The confirmation of Prussian case was dealt at the background of other important for Brandenburg questions as for example the de�livering the city of Elbing admitted already to the Elector by Commonwealth in treaty of Bromberg in 1657, which the Swedish did not want realize for the same reason as connected with hostile them treatises. At the end after a longer and hard negotiations in Peace of Oliva however was not concluded the special confirmation of release the elector from Fief in Duchy of Prussia and acknowledgment of his independence there but in Peace of Oliva was made a general confirmation all the treatises and agreements concluded during just the finished war what signified also the treatises between the Commonwealth and the Elector of Brandenburg from 1657.

Full text

Abstract:

Extensive cross testing on a relatively few legume hosts led initially to a taxonomic characterization of rhizobia based on bacteria–plant cross–inoculation groups. This has gradually become less acceptable, and has been replaced by taxonomic groupings derived from numerical taxonomy, carbohydrate metabolism, antibiotic susceptiblities, serology, and various molecular techniques. It has long been recognized that there are two distinct groups of rhizobia based on growth rate. The fast-growing genus Rhizobium includes R. leguminosarum, R. meliloti, R. loti, R. galegae, R. tropici, and R. huakuii. The slow-growing genus Bradyrhizobium contains only one recognized species, B. japonicum. Two new genera have been recognized: Azorhizobium, with one recognized species (A. caulinadans), and Sinorhizobium, with two species (S. fredii and S. xinjiangensis). Genetic studies of both the fast- and slow-growing groups show unacceptably wide intrageneric and intergeneric diversity. Although there have been some elegant studies of some of the genetic relationships among rhizobia, overall there has (have) not been the comprehensive study(ies) needed to allow a conclusive taxonomic scheme. Because proposals for revision are accelerating, minimum standards have been proposed by the International Subcommittee for the Taxonomy of Rhizobium and Agrobacterium. Key words: Rhizobium taxonomy, classification of rhizobia, interrelationships of rhizobia.

Abstract:

Genetically, Rhizobium sp. strain NGR234 and R. fredii USDA257 are closely related. Small differences in their nodulation genes result in NGR234 secreting larger amounts of more diverse lipo-oligosaccharidic Nod factors than USDA257. What effects these differences have on nodulation were analyzed by inoculating 452 species of legumes, representing all three subfamilies of the Leguminosae, as well as the nonlegume Parasponia andersonii, with both strains. The two bacteria nodulated P. andersonii, induced ineffective outgrowths on Delonix regia, and nodulated Chamaecrista fasciculata, a member of the only nodulating genus of the Caesalpinieae tested. Both strains nodulated a range of mimosoid legumes, especially the Australian species of Acacia, and the tribe Ingeae. Highest compatibilities were found with the papilionoid tribes Phaseoleae and Desmodieae. On Vigna spp. (Phaseoleae), both bacteria formed more effective symbioses than rhizobia of the “cowpea” (V. unguiculata) miscellany. USDA257 nodulated an exact subset (79 genera) of the NGR234 hosts (112 genera). If only one of the bacteria formed effective, nitrogen-fixing nodules it was usually NGR234. The only exceptions were with Apios americana, Glycine max, and G. soja. Few correlations can be drawn between Nod-factor substituents and the ability to nodulate specific legumes. Relationships between the ability to nodulate and the origin of the host were not apparent. As both P. andersonii and NGR234 originate from Indonesia/Malaysia/Papua New Guinea, and NGR234's preferred hosts (Desmodiinae/ Phaseoleae) are largely Asian, we suggest that broad host range originated in Southeast Asia and spread outward.

Abstract:

Plants that interact with pathogenic bacteria in their natural environments have developed barriers to block or contain the infection. Phytopathogenic bacteria have evolved mechanisms to subvert these defenses and promote infection. Thus, the type 3 secretion system (T3SS) delivers bacterial effectors directly into the plant cells to alter host signaling and suppress defenses, providing an appropriate environment for bacterial multiplication. Some rhizobial strains possess a symbiotic T3SS that seems to be involved in the suppression of host defenses to promote nodulation and determine the host range. In this work, we show that the inactivation of the Sinorhizobium (Ensifer) fredii HH103 T3SS negatively affects soybean nodulation in the early stages of the symbiotic process, which is associated with a reduction of the expression of early nodulation genes. This symbiotic phenotype could be the consequence of the bacterial triggering of soybean defense responses associated with the production of salicylic acid (SA) and the impairment of the T3SS mutant to suppress these responses. Interestingly, the early induction of the transcription of GmMPK4, which negatively regulates SA accumulation and defense responses in soybean via WRKY33, could be associated with the differential defense responses induced by the parental and the T3SS mutant strain.

Abstract:

We explored the genetic basis of the promiscuous symbiosis of Sophora flavescens with diverse rhizobia. To determine the impact of Nod factors (NFs) on the symbiosis of S. flavescens, nodulation-related gene mutants of representative rhizobial strains were generated. Strains with mutations in common nodulation genes (nodC, nodM, and nodE) failed to nodulate S. flavescens, indicating that the promiscuous nodulation of this plant is strictly dependent on the basic NF structure. Mutations of the NF decoration genes nodH, nodS, nodZ, and noeI did not affect the nodulation of S. flavescens, but these mutations affected the nitrogen-fixation efficiency of nodules. Wild-type Bradyrhizobium diazoefficiens USDA110 cannot nodulate S. flavescens, but we obtained 14 Tn5 mutants of B. diazoefficiens that nodulated S. flavescens. This suggested that the mutations had disrupted a negative regulator that prevents nodulation of S. flavescens, leading to nonspecific nodulation. For Ensifer fredii CCBAU 45436 mutants, the minimal NF structure was sufficient for nodulation of soybean and S. flavescens. In summary, the mechanism of promiscuous symbiosis of S. flavescens with rhizobia might be related to its nonspecific recognition of NF structures, and the host specificity of rhizobia may also be controlled by currently unknown nodulation-related genes.

Abstract:

Phosphate homeostasis is tightly modulated in all organisms, including bacteria, which harbor both high- and low-affinity transporters acting under conditions of fluctuating phosphate levels. It was thought that nitrogen-fixing rhizobia, named bacteroids, inhabiting root nodules of legumes are not phosphate limited. Here, we show that the high-affinity phosphate transporter PstSCAB, rather than the low-affinity phosphate transporter Pit, is essential for effective nitrogen fixation of Sinorhizobium fredii in soybean nodules. Symbiotic and growth defects of the pst mutant can be effectively restored by knocking out PhoB, the transcriptional repressor of pit. The pst homologs of representative rhizobia were actively transcribed in bacteroids without terminal differentiation in nodules of diverse legumes (soybean, pigeonpea, cowpea, common bean, and Sophora flavescens) but exhibited a basal expression level in terminally differentiated bacteroids (alfalfa, pea, and peanut). Rhizobium leguminosarum bv. viciae Rlv3841 undergoes characteristic nonterminal and terminal differentiations in nodules of S. flavescens and pea, respectively. The pst mutant of Rlv3841 showed impaired adaptation to the nodule environment of S. flavescens but was indistinguishable from the wild-type strain in pea nodules. Taken together, root nodule rhizobia can be either phosphate limited or nonlimited regarding the rhizobial differentiation fate, which is a host-dependent feature.

Abstract:

ABSTRACT Lipopolysaccharides (LPS) and capsular polysaccharides (K antigens) may influence the interaction of rhizobia with their specific hosts; therefore, we conducted a comparative analysis of Sinorhizobium fredii and Sinorhizobium meliloti, which are genetically related, yet symbiotically distinct, nitrogen-fixing microsymbionts of legumes. We found that both species typically produce strain-specific K antigens that consist of 3-deoxy-d-manno-2-octulosonic acid (Kdo), or other 1-carboxy-2-keto-3-deoxy sugars (such as sialic acid), and hexoses. The K antigens of each strain are distinguished by glycosyl composition, anomeric configuration, acetylation, and molecular weight distribution. One consistent difference between the K antigens ofS. fredii and those of S. meliloti is the presence of N-acetyl groups in the polysaccharides of the latter. In contrast to the K antigens, the LPS ofSinorhizobium spp. are major common antigens. Rough (R) LPS is the predominant form of LPS produced by cultured cells, and some strains release almost no detectable smooth (S) LPS upon extraction.Sinorhizobium spp. are delineated into two major RLPS core serogroups, which do not correspond to species (i.e., host range). The O antigens of the SLPS, when present, have similar degrees of polymerization and appear to be structurally conserved throughout the genus. Interestingly, one strain was found to be distinct from all others: S. fredii HH303 produces a unique K antigen, which contains galacturonic acid and rhamnose, and the RLPS did not fall into either of the RLPS core serogroups. The results of this study indicate that the conserved S- and RLPS of Sinorhizobiumspp. lack the structural information necessary to influence host specificity, whereas the variable K antigens may affect strain-cultivar interactions.

Abstract:

Symbiotic nitrogen fixation between legumes and rhizobia involves a coordinated expression of many plant and bacterial genes as well as finely tuned metabolic activities of micro- and macrosymbionts. In spite of such complex interactions, symbiotic proficiency remains a resilient process, with host plants apparently capable of compensating for some deficiencies in rhizobia. What controls nodule homeostasis is still poorly understood and probably varies between plant species. In this respect, the promiscuous Sinorhizobium (Ensifer) fredii strain NGR234 has become a model to assess the relative contribution of single gene products to many symbioses. Here, we describe how a deletion in nifQ of NGR234 (strain NGRΔnifQ) makes nodules of Vigna unguiculata, V. radiata, and Macroptilium atropurpureum but not of the mimisoid tree Leucaena leucocephala, purple-red. This peculiar dark-nodule phenotype did not necessarily correlate with a decreased proficiency of NGRΔnifQ but coincided with a 20-fold or more accumulation of coproporphyrin III and uroporphyrin III in V. unguiculata nodules. Porphyrin accumulation was not restricted to plant cells infected with bacteroids but also extended to the nodule cortex. Nodule metal-homeostasis was altered but not sufficiently to prevent assembly and functioning of nitrogenase. Although the role of NifQ in donating molybdenum during assembly of nitrogenase cofactor FeMo-co makes it essential in free-living diazotrophs, our results highlight the dispensability of NifQ in many legume species.

Abstract:

Gram-negative bacteria can produce outer membrane vesicles (OMVs), and most functional studies of OMVs have been focused on mammalian-bacterial interactions. However, research on the OMVs of rhizobia is still limited. In this work, we isolated and purified OMVs from Sinorhizobium fredii HH103 under free-living conditions that were set as control (C-OMVs) and symbiosis-mimicking conditions that were induced by genistein (G-OMVs). The soybean roots treated with G-OMVs displayed significant deformation of root hairs. G-OMVs significantly induced the expression of nodulation genes related to early symbiosis, while they inhibited that of the defense genes of soybean. Proteomics analysis identified a total of 93 differential proteins between C-OMVs and G-OMVs, which are mainly associated with ribosome synthesis, flagellar assembly, two-component system, ABC transporters, oxidative phosphorylation, nitrogen metabolism, quorum sensing, glycerophospholipid metabolism, and peptidoglycan biosynthesis. A total of 45 differential lipids were identified through lipidomics analysis. Correlation analysis of OMV proteome and lipidome data revealed that glycerophospholipid metabolism is the enriched Kyoto Encyclopedia of Genes and Genomes metabolic pathway, and the expression of phosphatidylserine decarboxylase was significantly up-regulated in G-OMVs. The changes in three lipids related to symbiosis in the glycerophospholipid metabolism pathway were verified by enzyme-linked immunosorbent assay. Our results indicate that glycerophospholipid metabolism contributes to rhizobia-soybean symbiosis via OMVs. [Formula: see text] Copyright © 2022 The Author(s).

Many representatives of the family were bishops (Greek-Catholic rite) or devoted themselves to military service. He was the grandson of the famous Polish comedy writer Aleksander Fredro. In the Austro-Hungarian army, he reached the rank of major general. During World War I, he joined the Polish Legions, becoming their leader in 1916. In 1917, he became the general governor of the Austro-Hungarian occupation in Lublin. As a sign of protest after the provisions of the Treaty of Brest-Litovsk (February 19, 1918) omitting Poland, he resigned. After the war, he joined the Polish Army, taking the position of Chief of the General Staff. He fought in the Polish-Soviet war and was the commander of a division, the 4th Army, and the front of „Gen. Stanisław Szeptycki” and then the North-Eastern Front. After the July Soviet offensive by M. Tuchaczewski in 1920, due to illness, he was removed from command of the front. As a result of differences in the assessment of Polish military activities, he entered into a dispute with Józef Piłsudski. In 1921, he became the commander of the Inspectorate of the Army No. IV in Krakow, and then the minister of military affairs in the government of Wincenty Witos. Opponent of Józef Piłsudski. In 1926, after the coup, the state retired.

Abstract:

Abstract Epigenetic age (EA) may serve as a risk stratification biomarker for early-onset colorectal cancer (EOCRC, <50 years old), which has been rising substantially in recent decades. We utilized publicly available data in a descriptive analysis to compare epigenetic clocks in colorectal tissue and to investigate differences between chronological age (CA) and biological age, as measured by EA, in relation to demographic and clinical features. We analyzed DNA methylation (DNAm) array data on 144 participants (96 CRC cases, 48 healthy controls) from the Colonomics Study (CLX; Barcelona, Spain) and 331 CRC cases (51 EOCRC, 316 average-onset (≥50) colorectal cancer (AOCRC)) from The Cancer Genome Atlas (TCGA) as well as corresponding demographic and clinical variables. Among CLX participants, the 96 CRC cases provided colon tumor and paired normal mucosa samples, while the 48 controls provided healthy colon mucosa samples. TCGA included primary tumor samples from 331 cases with colon or rectal adenocarcinoma (TCGA-COADREAD). The 2013 Horvath clock estimated EA based on CA, while epiTOC, estimated the relative stem cell division rate from tissue biospecimens. We examined the correlations between CA and EA stratified by case/control status, sample type, sex, and age of onset (TCGA only). Tissue from CLX controls demonstrated a strong, positive correlation (r>0.9) between CA and EA for both the 2013 Horvath and epiTOC clocks. Using the Horvath clock, CA and EA correlations in normal mucosa and tumor tissue samples from CLX varied, with r = 0.74 and r = 0.41, respectively, and were weaker using the epiTOC clock, with r = 0.26 (normal) and r = 0.10 (tumor). When CLX cases were stratified by sex, the CA and EA (Horvath) correlations among female cases were r = 0.80 (normal) and r = -0.12 (tumor), while the correlations for males were stronger at r = 0.58 (normal) and r = 0.31 (tumor). This is in comparison to the epiTOC clock with females showing correlations of r = -0.02 (normal) and r = 0.41 (tumor), while males had r = 0.06 (normal) and r = 0.11 (tumor). In TCGA, correlations for EOCRC were r = -0.20 (Horvath) and r = -0.08 (epiTOC) and for AOCRC were r = 0.29 and 0.20, respectively. By sex, correlations for females with EOCRC for Horvath and epiTOC were r = -0.09 and r = -0.07, respectively, while correlations for males with EOCRC were r = -0.02 and r = -0.08, respectively. For TCGA cases with AOCRC, the correlations between CA and EA were r = 0.35 and r = 0.22 for females, and r = 0.26 and r = 0.20 for males, respectively for Horvath and epiTOC. This study revealed substantial variability in the ability of existing epigenetic clocks to accurately predict chronological age, with tissue type and sex strongly influencing the resulting correlations. Our findings highlight the importance of considering these factors when choosing an epigenetic clock. Citation Format: Christopher L.

Abstract:

Quantum-dot cellular automata (QCA) is a developing nanotechnology, which seems to be a good candidate to replace the conventional complementary metal-oxide-semiconductor (CMOS) technology. The QCA has the advantages of very low power dissipation, faster switching speed, and extremely low circuit area, which can be used in designing nanoscale reversible circuits. In this paper, the new efficient QCA implementations of the basic reversible Gates such as: CNOT, Toffoli, Feynman, Double Feynman, Fredkin, Peres, MCL, and R Gates are presented based on the straight interactions between the QCA cells. Also, the designs of 4-Bit reversible parity checker and 3-bit reversible binary to Grey converter are introduced using these optimized reversible Gates. The proposed layouts are designed and simulated using QCADesigner software. In comparison with previous QCA designs, the proposed layouts are implemented with the minimum area, minimum number of cells, and minimum delay without any wire-crossing techniques. Also, in comparison with the CMOS technology, the proposed layouts are more efficient in terms of the area and power. Therefore, our designs can be used to realize quantum computation in ultralow power computer communication.

Abstract:

Celem artykułu jest pokazanie wyjątkowych zasług polskich literaturoznawców związanych ze Lwowem w badaniach romantyzmu na tle osiągnięć uczonych z innych polskich uniwersytetów. Analizowany problem obejmuje okres do roku 1939, ponieważ dotąd funkcjonował we Lwowie polski uniwersytet. Zainteresowanie rodzimym romantyzmem, zwłaszcza trójcą wieszczów: Adamem Mickiewiczem, Juliuszem Słowackim i Zygmuntem Krasińskim, dominowało w pracach naukowych filologów epoki pozytywizmu, Młodej Polski i dwudziestolecia międzywojennego. Porównanie dorobku Lwowa z „resztą Polski” obejmuje monografie największych pisarzy i ich ocenę, rozprawy i artykuły oraz stosowaną w badaniach metodologię. W czasach zaborów (do 1918 r.) poloniści lwowscy konkurowali głównie z krakowskimi (UJ) i kilkoma z Warszawy. W Krakowie powstało najwięcej monografii trzech wieszczów, ale to we Lwowie Juliusz Kleiner napisał najlepszą (o Krasińskim). Filolodzy krakowscy stosowali przestarzałą metodologię (oceniali literaturę ze względu na poglądy ideologiczne pisarzy, nie interpretowali samych dzieł). We Lwowie badano głównie teksty utworów literackich, ich wartość artystyczną. Przed rokiem 1914 Juliusz Kleiner stworzył nowoczesną metodologię (dzieło literackie w centrum zainteresowań). Sformułował też pojęcie epoki romantyzmu, które przyswoili potem inni uczeni. Poglądy Kleinera stały się podstawą w badaniach literatury w dwudziestoleciu międzywojennym. W wolnej Polsce w latach 1919–1939 działało sześć uniwersytetów: we Lwowie, Krakowie, Warszawie, Wilnie, Lublinie i Poznaniu. Polonistyka we Lwowie przeżywała wtedy okres największej świetności. To kolejne zasługi wybitnego Juliusza Kleinera, uznawane za najlepsze w Polsce i ponadczasowe: dwie ogromne monografie – Słowackiego i Mickiewicza, znakomicie opracowane Dzieła wszystkie Słowackiego (większość tomów), historia literatury polskiej po polsku i niemiecku i inne. We Lwowie pracował Eugeniusz Kucharski – najlepszy w Polsce znawca Aleksandra Fredry; Konstanty Wojciechowski i Zygmunt Szweykowski – najwybitniejsi specjaliści od polskiej powieści. We Lwowie działało od 1886 r. Towarzystwo Literackie im. Adama Mickiewicza (w innych miastach po roku 1919 jego filie). Tam też ukazywał się „Pamiętnik Literacki” – najbardziej zasłużone czasopismo badaczy literatury. W porównaniu z pozostałymi miastami we Lwowie najliczniejsza grupa uczonych badała polski romantyzm i poświęciła mu najwięcej publikacji.
