Abstract (sommario):

ABSTRACTCrown gall disease of grapevine is caused by virulentAgrobacteriumstrains and establishes a suitable habitat for agrobacteria and, potentially, other bacteria. The microbial community associated with grapevine plants has not been investigated with respect to this disease, which frequently results in monetary losses. This study compares the endophytic microbiota of organs from grapevine plants with or without crown gall disease and the surrounding vineyard soil over the growing seasons of 1 year. Amplicon-based community profiling revealed that the dominating factor causing differences between the grapevine microbiota is the sample site, not the crown gall disease. The soil showed the highest microbial diversity, which decreased with the distance from the soil over the root and the graft union of the trunk to the cane. Only the graft union microbiota was significantly affected by crown gall disease. The bacterial community of graft unions without a crown gall hosted transient microbiota, with the three most abundant bacterial species changing from season to season. In contrast, graft unions with a crown gall had a higher species richness, which in every season was dominated by the same three bacteria (Pseudomonassp.,Enterobacteriaceaesp., andAgrobacterium vitis). Forin vitro-cultivated grapevine plantlets,A. vitisinfection alone was sufficient to cause crown gall disease. Our data show that microbiota in crown galls is more stable over time than microbiota in healthy graft unions and that the microbial community is not essential for crown gall disease outbreak.IMPORTANCEThe characterization of bacterial populations in animal and human diseases using high-throughput deep-sequencing technologies, such as 16S amplicon sequencing, will ideally result in the identification of disease-specific microbiota. We analyzed the microbiota of the crown gall disease of grapevine, which is caused by infection with the bacterial pathogenAgrobacterium vitis.All otherAgrobacteriumspecies were found to be avirulent, even though they lived together withA. vitisin the same crown gall tumor. As has been reported for human cancer, the crown gall tumor also hosted opportunistic bacteria that are adapted to the tumor microenvironment. Characterization of the microbiota in various diseases using amplicon sequencing may help in early diagnosis, to serve as a preventative measure of disease in the future.

Abstract (sommario):

The nonpathogenic strain of Agrobacterium (=Rhizobium) vitis ARK-1 is a biological agent able to effectively control grapevine crown gall. In this study, treating apple, Japanese pear, peach, rose, and tomato by soaking the roots in a cell suspension of ARK-1 before planting into soil infected with tumorigenic Agrobacterium spp. reduced the number of plants developing crown gall tumors. Meta-analyses of the results from six field trials of apple, four field trials of Japanese pear, and four field trials of peach, from 2010 to 2013, showed integrated risk ratio (IRR) after treatment with ARK-1 to be 0.38 for apple crown gall, 0.16 for Japanese pear crown gall, and 0.20 for peach crown gall, indicating that the disease incidence was significantly reduced by ARK-1 treatment. Meta-analyses of the results from three greenhouse trials of rose and three greenhouse trials of tomato showed IRR after treatment with ARK-1 to be 0.29 for rose crown gall and 0.16 for tomato crown gall, indicating that the disease incidence was significantly reduced by ARK-1 treatment. These results indicated that control by ARK-1 covers five different species of host plants and tumorigenic (Ti) strains of Agrobacterium species.

Abstract (sommario):

Crown gall induced by Agrobacterium vitis is a worldwide plant disease in grape-growing regions. Rahnella aquatilis HX2, a new isolate from vineyard soil in Beijing, showed a significant inhibition effect on the development of crown galls in grapevines. In field trials, immersion of the basal ends of grape cuttings with HX2 cell suspension inhibited or completely prevented crown gall formation caused by A. vitis K308 in the roots of the plants from the cuttings. The 3-year average disease incidence in grape plants treated with HX2 was 30.8% compared to 93.5% in plants without HX2. The culture supernatant of HX2 exhibited a stronger inhibition effect on disease development than did the cell suspension. HX2 could be found in the grape rhizosphere, grown under field conditions, for up to 90 days after inoculation. There was no significant difference in the mean population sizes of root microflora between plants treated and not treated with HX2. The inhibition effect of HX2 on crown gall in sunflower, caused by different agrobacterial strains, varied between 30.7 and 100%, depending on strains. Our results showed that Rahnella aquatilis HX2 may be used as a biological control agent for crown gall disease of grapes.

Abstract (sommario):

Crown gall is a globally distributed and economically important disease of grapevine and other important crop plants. The causal agent of grapevine crown gall is tumorigenic Allorhizobium vitis (Ti) strains that harbor a tumor-inducing plasmid (pTi). The epidemic of grapevine crown gall has not been widely elucidated. In this study, we investigated the genetic diversity of 89 strains of Ti and nonpathogenic A. vitis to clarify their molecular epidemiology. Multi-locus sequence analysis (MLSA) of the partial nucleotide sequences of pyrG, recA, and rpoD was performed for molecular typing of A. vitis strains isolated from grapevines with crown gall symptoms grown in 30 different vineyards, five different countries, mainly in Japan, and seven genomic groups A to F were obtained. The results of MLSA and logistic regression indicated that the population of genetic group A was significantly related to a range of prefectures and that the epidemic of group A strains originated mainly in Hokkaido in Japan through soil infection. Moreover, group E strains could have been transported by infected nursery stocks. In conclusion, this study indicates that both soil infection and transporting of infected nursery stocks are working as infection source in Hokkaido.

Abstract (sommario):

Thirty-four cultivars of pea (Pisum sativum) were assayed for tumorigenesis after inoculation with Agrobacterium tumefaciens strain B6. The response of the 34 cultivars fell into 3 significantly different groups based on tumor weights: high, medium, and low susceptibility. The least susceptible cultivar, Sweet Snap, also formed the smallest tumors in comparison to 5 other cultivars when inoculated with 5 other strains of Agrobacterium. Preliminary experiments indicate that neither chemotaxis, binding, vir-gene induction, nor T-DNA expression are limiting factors in Sweet Snap's reduced susceptibility. In an inheritance study, the F1, F2, and F3 progeny from an initial cross between Sweet Snap and Wando (a more susceptible cultivar) formed tumors that were intermediate in weight between the two parents.

Abstract (sommario):

Agrobacterium tumefaciens is a gram-negative soil bacterium that causes crown gall tumors on dicotyledenous plants. The transferred DNA (T-DNA) portion of the A. tumefaciens tumor-inducing (Ti) plasmid enters infected plant cells and integrates into plant nuclear DNA. The T-DNA is accompanied into plant cells by the VirD2 endonuclease covalently attached to its 5' end. VirE2, a cooperative, single-stranded DNA-binding protein is also transported into plant cells during infection by A. tumefaciens. VirD2 and VirE2 contain nuclear localization signals (NLSs) and are transported into the plant cell nucleus. The location of functional domains by the insertion of Xhol linker oligonucleotides throughout virE2 is reported. A ssDNA binding domain was located in the C-terminal half of VirE2, as well two domains involved in cooperative single-stranded DNA binding. Further, we isolated a mutation in the central region of VirE2 that decreased tumorigenicity, but did not affect ssDNA binding.

In Taiwan, the cultivation area of roselle is about 124.88 hectare. Taitung county is main region for production of roselle. Since 2016, a new crown gall disease was found in the commercial plantations of roselle (Hibiscus sabdariffa) throughout Taimali and Jinfong in Taitung County. In summer 2017, we found the disease spread out to the other areas South of Ziben in Taitung County, and the estimated disease incidence was about 0.6-10%. Through Koch’s postulate, it was proved that the bacterial strains isolated from crown galls formed on roselle are pathogenic to roselle. They can induce gall formation on the stems of roselle, from which the same bacterial strain can be re-isolated, indicating that it should be the causal agent. Colony morphology of the isolated bacterial strain is viscous and milky white in color on the tryptone soy agar (TSA). In a carrot slice bioassay, tumor formation could be observed on the cambial regions after inoculation of the isolated strains. The pathogenic bacteria isolated in this study are rod-shaped and have peritrichous flagella. By means of 16S rDNA sequence analysis, recA-specific primers and Biolog microbial identification system, they were identified as Agrobacterium radiobacter (Beijerinck and van Delden 1902) Conn 1942 (Synonyms: Agrobacterium tumefaciens and Rhizobium radiobacter) whose physiological and biochemical characterisitics are similar to Agrobacterium rubi. As this disease was not recorded in “List of Plant Diseases in Taiwan” and is a new disease of roselle, it was then named “roselle crown gall disease”. A. radiobacter can grow from 20 to 37 °C, and pH 6-7 is optimal for its growth. It can induce tumor formation by stem puncture inoculation or soil drenching as long as wounds are present. When stem puncture inoculation was used, the minimal infection dose is 104 cfu/mL. Furthermore, significantly bigger galls were formed on meristems when the inoculum was 109 cfu/mL. Disinfection of equipment with 75 % ethanol and 3 % NaOCl can decrease the possibility of infection through pruning. Furthermore, Pseudomonas protegens XH1-2a、Pantoea ananatis A63 and Bacillus amyloliquefaciens PMB01, as well as tetracycline, streptomycin+ tetracycline and mancozeb, can inhibit growth of A. radiobacter in a disk diffusion test. In a greenhouse assay, although tumors were still formed after application of P. protegens XH1-2a, smaller galls could be observed when plants were treated with P. protegens XH1-2a before or together with A. radiobacter. Application of tetracycline before pathogen inoculation could effectively suppress gall formation. Tumor was barely formed while roselle plants were inoculated with A. radiobacter mixed with tetracycline. A. radiobacter could weaken roselle plants. Although it would not kill roselle plants, A. radiobacter might affect growth and yield of roselle when the diseas is getting worse. In this study, the causing agent of roselle crown gall disease was successfully identified and characterized, which would help us further investigate its ecology and develop control strategies for prevention or treatment of roselle crown gall disease to reduce the economic loss.

Abstract (sommario):

This chapter investigates the cat scratch disease (CSD), which was first described in 1950 by Rene Debré as “La Maladie de Griff de Chat.” It points out how CSD cause remained a mystery until the late twentieth century, when amplification and sequencing of 16S rRNA genes was introduced as a method of identifying organisms that had not been successfully cultured. It also mentions David Relman, who identified the agent of CSD as a small gram-negative coccobacillus that is closely related to the agents causing trench fever, brucellosis, and crown gall disease in plants. The chapter talks about Rochalimaea henselae, Bartonella bacilliformis, and Bartonella rochalimae that share the ability to invade vascular endothelial cells, bone marrow erythroblasts, and mature erythrocytes. It highlights the manifestations of CSD and the expanding roster of Bartonella species that populate mammalian reservoirs.

Abstract (sommario):

The aim of this study was to carry out a global functional genomics analysis of plant cell transformation by Agrobacterium in order to define and characterize the physiology of Agrobacterium in the acidic environment of a wounded plant. We planed to study the proteome and transcriptome of Agrobacterium in response to a change in pH, from 7.2 to 5.5 and identify genes and circuits directly involved in this change. Bacteria-plant interactions involve a large number of global regulatory systems, which are essential for protection against new stressful conditions. The interaction of bacteria with their hosts has been previously studied by genetic-physiological methods. We wanted to make use of the new capabilities to study these interactions on a global scale, using transcription analysis (transcriptomics, microarrays) and proteomics (2D gel electrophoresis and mass spectrometry). The results provided extensive data on the functional genomics under conditions that partially mimic plant infection and – in addition - revealed some surprising and significant data. Thus, we identified the genes whose expression is modulated when Agrobacterium is grown under the acidic conditions found in the rhizosphere (pH 5.5), an essential environmental factor in Agrobacterium – plant interactions essential for induction of the virulence program by plant signal molecules. Among the 45 genes whose expression was significantly elevated, of special interest is the two-component chromosomally encoded system, ChvG/I which is involved in regulating acid inducible genes. A second exciting system under acid and ChvG/Icontrol is a secretion system for proteins, T6SS, encoded by 14 genes which appears to be important for Rhizobium leguminosarum nodule formation and nitrogen fixation and for virulence of Agrobacterium. The proteome analysis revealed that gamma aminobutyric acid (GABA), a metabolite secreted by wounded plants, induces the synthesis of an Agrobacterium lactonase which degrades the quorum sensing signal, N-acyl homoserine lactone (AHL), resulting in attenuation of virulence. In addition, through a transcriptomic analysis of Agrobacterium growing at the pH of the rhizosphere (pH=5.5), we demonstrated that salicylic acid (SA) a well-studied plant signal molecule important in plant defense, attenuates Agrobacterium virulence in two distinct ways - by down regulating the synthesis of the virulence (vir) genes required for the processing and transfer of the T-DNA and by inducing the same lactonase, which in turn degrades the AHL. Thus, GABA and SA with different molecular structures, induce the expression of these same genes. The identification of genes whose expression is modulated by conditions that mimic plant infection, as well as the identification of regulatory molecules that help control the early stages of infection, advance our understanding of this complex bacterial-plant interaction and has immediate potential applications to modify it. We expect that the data generated by our research will be used to develop novel strategies for the control of crown gall disease. Moreover, these results will also provide the basis for future biotechnological approaches that will use genetic manipulations to improve bacterial-plant interactions, leading to more efficient DNA transfer to recalcitrant plants and robust symbiosis. These advances will, in turn, contribute to plant protection by introducing genes for resistance against other bacteria, pests and environmental stress.
