Abstract:

Abstract The Brassica genotypes selected for the experiments were previously found to be resistant to various Plasmodiophora brassicae pathotypes (Pb). Their interaction with pathotypes Pb2, Pb3 and Pb9 isolated in Poland was studied, using macroscopic observation for the presence of root galls, microscopic observations of P. brassicae plasmodia in the root hairs and quantitative PCR for determination of the pathogen’s quantity in plant roots and growing media. Of the Brassica genotypes studied, only B. rapa var. capitata line AABBcc was fully resistant to all the Polish pathotypes of P. brassicae. Some of the other “clubroot-resistant” genotypes tested were resistant to selected pathotypes, e.g. Brassica napus var. rapifera ‘Wilhelmsburger’ to Pb 2 and Pb3, Brassica oleracea var. capitata ‘Kilaton F1’ to Pb2 and Brassica rapa subsp. pekinensis ‘Bilko F1’ to Pb3, but were susceptible to others. B. oleracea var. capitata ‘Bindsachsener’, B. oleracea var. acephala subvar. lacinata ‘Verheul’ and B. napus var. napus ‘Mendel F1’ were moderately to highly susceptible to all Polish P. brassicae pathotypes. These results show that the classification of virulence of P. brassicae pathotypes selected in various areas differs significantly toward the same Brasssica genotypes and puts in question the practical value of pathotype classification determined with differential sets for farmers and plant breeders. Our results showed that B. rapa var. capitata AABBcc line, B. napus var. rapifera ‘Wilhelmsburger’, B. oleracea var. capitata ‘Kilaton F1’, B. rapa subsp. pekinensis ‘Bilko F1’ could be considered in Brassica breeding programmes as a source of resistance to Polish P. brassicae isolates.

Abstract:

Growing resistant cultivars from the Brassicaceae family (brassicas) is an effective strategy to minimize crop loss caused by the soilborne pathogen Plasmodiophora brassicae (clubroot). However, there are many clubroot pathotypes, and genetic resistance to clubroot may be pathotype-specific. To determine which pathotypes are present in western Oregon, diseased roots were collected from five farms and identified by the European clubroot differential (ECD) set. To assess resistance to the identified pathotypes, 21 vegetable cultivars from nine crops with purported resistance to clubroot were evaluated for disease incidence and severity in field and greenhouse studies. The crops evaluated included broccoli (Brassica oleracea var. italica), cauliflower (B. oleracea var. botrytis), brussels sprouts (B. oleracea var. gemmifera), cabbage (B. oleracea var. capitata), napa cabbage (Brassica rapa var. pekinensis), pak choi (B. rapa var. chinensis), kohlrabi (B. oleracea var. gongylodes), turnip (B. rapa var. rapa), and rutabaga (Brassica napus var. napobrassica). ECD host reaction showed similar virulence among clubroot collections, and all field isolates had the same ECD pathotype designation, 16/02/30. Compared with a crop-specific susceptible control, 17 of 21 cultivars had some resistance to clubroot, and of those, 15 were highly resistant (≤15% incidence with low disease severity). This research demonstrated that western Oregon farmers have several commercially available cultivars with resistance to the dominant pathotyope in the region. However, each farmer must evaluate the suitability of these cultivars to meet consumer and industry requirements.

Abstract:

Samples of Brassica oleracea seed from Victoria, were tested for the presence of seed-borne Alternaria brassicicola and Alternaria brassicae. A. brassicicola was detected in 26 of 44 samples tested but A. brassicae was not detected in any. Between 24 and 37% of seed was infected, with 4-8% of infection found in the embryo tissues. Inoculation of seed with A. brassicicola resulted in loss of vigour in germinated seedlings, followed by death. The fungus retained its viability and pathogenicity on seed stored for up to 12 months. This investigation indicates that a high proportion of commercially available brassica seed are contaminated with A. brassicicola and may therefore be a primary source of disease for brassica crops in Australia.

Abstract:

F2 segregation analyses of DNA restriction fragment length polymorphisms (RFLPs) detected between a cabbage line (No. 86-16-5) resistant to race 2 of Plasmodiophora brassicae (Woronin), the fungus responsible for clubroot disease, and a rapid cycling line (CrGC No. 85) was used to construct a detailed genetic map of Brassica oleracea. RFLP markers were random and seedling-specific cDNA clones. The 201 loci so far mapped in B. oleracea covered 1112 cM. They are assembled into nine major linkage groups and four small linkage groups. Twelve loci were found unlinked to any other markers. Twenty-one loci were detected with the 18 seedling-specific cDNAs. Two dominant QTLs for resistance to race 2 of the clubroot disease causal agent were also identified. Leaf morphology and biennial flowering appeared to segregate as single Mendelian traits, but only leaf morphology could be linked to other markers. This RFLP study in B. oleracea is providing additional information on genome organization and complements current RFLP mapping effort in B. napus.Key words: genetic mapping, Brassica oleracea, Plasmodiophora brassicae, breeding, clubroot resistance, DNA markers, RFLP.

Abstract:

Research on the environmental risks of gene flow from genetically modified (GM) crops to wild relatives has traditionally emphasized recipients yielding most hybrids. For GM rapeseed ( Brassica napus ), interest has centred on the ‘frequently hybridizing’ Brassica rapa over relatives such as Brassica oleracea , where spontaneous hybrids are unreported in the wild. In two sites, where rapeseed and wild B. oleracea grow together, we used flow cytometry and crop-specific microsatellite markers to identify one triploid F 1 hybrid, together with nine diploid and two near triploid introgressants. Given the newly discovered capacity for spontaneous introgression into B. oleracea , we then surveyed associated flora and fauna to evaluate the capacity of both recipients to harm cohabitant species with acknowledged conservational importance. Only B. oleracea occupies rich communities containing species afforded legislative protection; these include one rare micromoth species that feeds on B. oleracea and warrants further assessment. We conclude that increased attention should now focus on B. oleracea and similar species that yield few crop-hybrids, but possess scope to affect rare or endangered associates.

Abstract:

Methanethiol (MT) is a volatile compound responsible for the unpleasant odor evolved when fresh broccoli (Brassica oleracea L., Italica group) is held under anaerobic conditions. Inductive atmospheres can develop in storage, transportation containers, or modified atmosphere packages, resulting in reduced quality. To determine if related vegetables are capable of producing MT, 12 different vegetables from the genus Brassica were cut into ready-to-eat forms. Fifty-gram samples were sealed in 500-mL glass jars and flushed with N2. After 24 h in the dark at 20 °C, headspace samples from the jars were analyzed for MT and other volatiles. Headspace concentration of MT was greatest in broccoli florets, followed by pak choi (Brassica rapa L., Chinensis group) leaf blades, savoy cabbage (Brassica oleracea L., Capitata group), broccoflower (Brassica oleracea L., Botrytis group), and green and red cabbage (Brassica oleracea L., Capitata group). Broccoli stems, kale (Brassica oleracea L., Acephala group), Brussels sprouts (Brassica oleracea L., Gemmifera group), pak choi petioles, rutabaga (Brassica napus L., Napobrassica group) root, cauliflower (Brassica oleracea L., Botrytis group) florets, Chinese cabbage (Brassica rapa L., Pekinensis group), and kohlrabi (Brassica oleracea L., Gongylodes group) tubers produced <3% of the MT produced by broccoli florets. Green tissues appeared to have a greater capacity to produce MT than nongreen tissues. Anaerobic production of CO2 and ethanol did not relate to the vegetable's ability to produce MT. The production of dimethyl disulfide (DMDS) and dimethyl trisulfide (DMTS) were also induced by the anaerobic conditions. Green cabbage produced the greatest concentration of DMDS, followed by savoy cabbage and broccoli florets. Production of DMTS was similar to the pattern observed for MT, but DMDS production was not highly correlated with MT production.

Abstract:

Experiments on three varieties of Brassica oleracea (white cabbage, red cabbage, and cauliflower) were conducted during the years 2008–2011 in Western Siberia (Russia) to study the influence of host plant on herbivore infestation. The results revealed the evidence of different infestation of white cabbage, red cabbage, and cauliflower by the common herbivores in Western Siberia. Flea beetles as the earliest herbivores preferred to infest white cabbage. Contrary to those herbivores, M. brassicae and P. xylostella larvae infested red cabbage most of all. The latest herbivore of all plants studied, P. brassicae, preferred cauliflower but not red cabbage. The possible contribution of some factors in summary effects observed in the study was discussed. Further studies are being planned in which tritrophic interaction including B. oleracea plant, herbivore, and microbial insecticides should be investigated. These studies will help to develop biological insect control on Brassica oleracea crops in order to supply ecologically safe plant protection.

Abstract:

AbstractPieris brassicae (Linn.) is a destructive cosmopolitan pest of cruciferous crops. It is present wherever its host plants occur, and it is considered to be one of the most widely distributed of all the Lepidoptera. We investigated the affect of various host plants on the food consumption and utilization by P. brassicae. We quantified consumption of food, larval duration, pupal duration and weight on cabbage (Brassica oleracea var. capitata), cauliflower (Brassica oleracea var. botrytis), radish (Raphanus sativus), broccoli (Brassica oleracea var. italica) and mustard (Brassica campestris) under laboratory conditions. Insect-host relationships can be better understood by knowing the rate of food consumption, its digestibility and conversion of food eaten to body tissue. The consumption of food generally increased with the advancement of larval age. In our study we found that consumption of food was highest on radish and lowest on broccoli. The highest consumption of a particular host does not always indicate greater suitability of that host, until and unless other factors like consumption index (CI), relative growth rate (RGR), efficiency of conversion of ingested food (ECI), approximate digestibility (AD) and efficiency of conversion of digested food (ECD) are also considered. In the current investigation, factors like CI, RGR, ECI and ECD were highest on cabbage. Low body weight of pupa is associated with rapid development. On cabbage, the weight of pupa of both sexes was found lowest. Thus, from the present study, it can be concluded that cabbage is a more suitable host for P. brassicae than other host plants evaluated. Hence, on cabbage, the values of Waldbauer indices were highest and P. brassicae developed with a faster rate.

Abstract:

Restriction-site variation for 17 endonucleases was compared in the large single-copy region of the chloroplast genome in 74 taxa of the genera Brassica, Coincya, Diplotaxis, Eruca, Erucastrwn, Hirschfeldia, Raphanus, Sinapidendron, Sinapis, and Trachystoma (subtribe Brassicinae, tribe Brassiceae, Cruciferae). A total of 422 restriction-site mutations was observed, with 228 (54%) showing variation among taxa. Phylogenetic analyses indicated a clear division of the subtribe into two main lineages designated here as Rapa–Oleracea and Nigra. Polyphyly was evident in five genera (Brassica, Diplotaxis, Erucastrum, Sinapis, and Trachystoma) as indicated by their placement in both lineages and (or) further separation into groups within a lineage. The genera Coincya, Hirschfeldia, and Sinapidendron were monophyletic within the Nigra lineage, as were Eruca and Raphanus in the Rapa–Oleracea lineage. Four major groups were recognized within each lineage. The lowest levels of chloroplast DNA divergence were observed among taxa belonging to the same cytodeme or crossing group and were highest for Brassica rapa and Brassica oleracea versus Brassica nigra at 2.10–3.91% and 2.00–3.78%, respectively. The chloroplast DNA data were incongruent with traditional taxonomic circumscription of 5 of the 10 genera but concordant with other data sets that support the close genetic relatedness of all 10 genera. Key words: Brassica, Coincya, Erucastrum, Sinapidendron, Trachystoma, chloroplast DNA restriction-site variation.

Abstract:

The study was conducted in two districts Comilla and Jessore to examine the marketing chain, marketing cost, and margin, problems and some probable solutions for cabbage and cauliflower marketing. A total of 92 respondents consisting of 20 vegetable growers and 72 vegetables traders were selected as sample for the present study. A multi-stage simple random sampling technique was used for selection of samples. Both primary and secondary data were used for the study. About 60% farmers used van to carry the vegetables to the market. Average cauliflower marketing cost of farmer was higher than cabbage which was Tk.36.59 per quintal due to its special transportation arrangement. On the basis of the intermediaries, seven marketing chain were identified as a dominant. The chain Farmer?Local Traders (Faria) ? Bepari? Aratdar (urban) ?Retailer (urban) ?Consumer was identified as most dominant. About 39.60% product runs through this chain. In cauliflower marketing local traders, Bepari, retailer (urban) and retailer (rural) incurred the highest marketing cost than cabbage which were averaged Tk.65.75, Tk.248.47, Tk.205.69, and Tk.78.21, respectively, due to its perishable nature. In the case of farmers, local traders (Faria) and Bepari transportation cost is the highest. Commission charge was highest in the case of retailer (urban) and spoilage and damage cost was the highest for retailer(rural).The marketing cost was the highest for Bepari which were estimated Tk.212.74 for cabbage, Tk.219.87 for cauliflower and the marketing margin was highest for retailer (urban) which were estimated Tk.108.52 for cabbage and Tk.130.09 for cauliflower. Inadequate storage facilities and dominance of intermediaries were the major marketing problems identified by the farmers. Unstable price, barrier to entry in the terminal market, delays on ferryghat and spoilage and damage were the major marketing problem faced by the different intermediaries. The study suggested improving the storage facilities and establishment of organization to solve marketing problem of the farmers. Easy access of vegetables carrying vehicle in the terminal market, arrangement of separate cargo ferry would reduce the spoilage and damage of vegetables in the traders level.

Abstract:

Brassicas form the most important group of vegetable crops in Montenegro. The cabbage (Brassica oleracea var. capitata) is most commonly grown, although other brassicas, particularly kale, Brussels sprout, cauliflower and broccoli, have been increasingly produced since recently. One of the specialties of vegetable production in Montenegro is growing of collard (Brassica oleracea var. acephala), which is the simplest variety of the Brassica oleracea species and in the nearest relation with their wild ancestor - the sylvestris variety. Diseases are the main restrictive factors for successful production of these vegetables. Susceptibility of the cultivars and inadequate control often result in more or less damaged crops in some plots. Causal agents of brassica diseases, especially bacterial, have not been investigated in Montenegro until 2009. Since the symptoms observed in 2009 were ?V? shaped leaf edge necrosis and black rot of vascular tissue, it was assumed that they were caused by plant pathogenic bacterium Xanthomonas campestris pv. campestris. Samples of the infected plants were collected from different localities in Montenegro. Isolation and identification of the bacterium were performed using laboratory methods according to Schaad (1980), Lelliott and Stead (1987) and Arsenijevic (1997). Examination of chosen bacterial isolates was conducted using both, classical bacteriological methods (examination of their pathogenic, morphological, cultivation and biochemical and physiological characteristics), and ELISA test. The obtained results confirmed the presence of X.campestris pv. campestris (Pammel, 1895) Dowson 1939, on cabbage, kale, broccoli and collard in Montenegro. This is the first experimental evidence that collard is the host of X. campestris pv. campestris in Montenegro.

AbstractIn exploring an effective and reliable karyotyping method in Brassica crop plants, Brassica oleracea was successfully karyotyped using genomic in situ hybridization (GISH). B. oleracea genomic DNA was labelled as probe using DIG-high prime mix kit, with B. rapa genomic DNA acting as blocking agent. Specific fluorescent signals were detected on each pair of homologous chromosomes, and nine pairs of chromosomes of B. oleracea were clearly identified according to the signal characteristics. A practical and accurate method for conducting karyotyping of small chromosomes has been demonstrated.

Abstract:

An improved protocol for Brassica protoplast culture and plant regeneration was developed. Isolated protoplasts from four-weeks-old in vitro shoot tip culture of Brassica oleracea var. botrytis cv. Siria F1 and Brassica napus doubled haploid of breeding line OP-1 were cultured at a density of 9.8–11.2 × 104 protoplasts/ml in darkness at 25°C in a modified medium containing 2% glucose, 0.25 mg/l 2,4-D, 1 mg/l BAP and 1 mg/l NAA. The first divisions of protoplasts were observed on the third day of culture in B. oleracea and on the fourth day in B. napus. The protoplast cultures were diluted with low osmotic medium on 7th and 11th day. The frequency of dividing cells was about 80% in B. oleracea and 50% in B. napus. After one month, the microcalli of approximately 0.5–1 mm in size were transferred into an induction medium with various combinations of growth regulators. Minimum duration of enzyme treatment time and extended dark period in the initial phase of culture increased the survival rate of protoplasts. Organogenesis started when the calli enlarged in size on an induction medium (1 mg/l NAA, 0.02 mg/l GA3, 1 mg/l 2iP) with 2% sucrose and 0.8% agar. Regeneration frequency of calli was found to be 69–75% in B. oleracea and 2–3% in B. napus. Well-developed shoots were transferred for rooting to a half-strength MS medium without growth regulators. More than 100 B. oleracea regenerants were transferred into soil, and they produced normal heads and set seeds. This very simple procedure is efficient and suitable mainly for B. oleracea var. botrytis and represents a background for fusion experiments.

Abstract:

This paper set out to comparatively study five species: white cabbage (Brassica oleracea L. var. capitata alba Alef.), red cabbage (Brassica oleracea L. var. capitata f. rubra Alef.), Kale (Brassica oleracea L. var. Acephala), cauliflower (Brassica oleracea var. botrytis) and broccoli (Brassica oleracea var. cymosa) in order to identify those with high enzymatic and antioxidant activities. The enzymatic activity of superoxide dismutase (SOD), catalase (CAT) and soluble peroxidase (POX) as well as the antioxidant activity against 2.2’-azino-bis (3-ethylbenzothiazoline-6-sulphonic acid (ABTS) radical cation were determined. Total superoxide dismutase activity was measured spectrophotometrically based on inhibition in the photochemical reduction of nitroblue tetrazolium. Total soluble peroxidase was assayed by measuring the increase in A436 due to the guaiacol oxidation and the catalase activity was assayed through the colorimetric method. The capacity of extracts to scavenge the ABTS radical cation was assessed colorimetric using Trolox as a standard. The obtained results show that studied enzymatic activities and the antioxidant activity against ABTS vary depending on the analyzed species. So, among the studied Brassicaceae species, it emphasize red cabbage with the highest enzymatic activity (CAT 22.54 mM H2O2/min/g and POX 187.2 mM ΔA/1min/1g f.w.) and kale with highest antioxidant activity, of 767 μmol TE/100g f.w. The results of this study recommendintroducing the studied varieties in diet due to the rich antioxidant properties.

Abstract:

Abstract The chromosomes of Arabidopsis thaliana and Brassica oleracea have been extensively rearranged since the divergence of these species; however, conserved regions are evident. Eleven regions of conserved organization were detected, ranging from 3.7 to 49.6 cM in A. thaliana, spanning 158.2 cM (24.6%) of the A. thaliana genome, and 245 cM (29.9%) of the B. oleracea genome. At least 17 translocations and 9 inversions distinguish the genomes of A. thaliana and B. oleracea. In one case B. oleracea homoeologs show a common marker order, which is distinguished from the A. thaliana order by a rearrangement, indicating that the lineages of A. thaliana and B. oleracea diverged prior to chromosomal duplication in the Brassica lineage (for at least this chromosome). Some chromosomal segments in B. oleracea appear to be triplicated, indicating the need for reevaluation of a classical model for Brassica chromosome evolution by duplication. The distribution of duplicated loci mapped for about 13% of the DNA probes studied in A. thaliana suggests that ancient duplications may also have occurred in Arabidopsis. The degree of chromosomal divergence between A. thaliana and B. oleracea appears greater than that found in other confamilial species for which comparative maps are available.

Abstract:

The close relationship between Brassica oleracea and Arabidopsis thaliana has been used to explore the genetic and physical collinearity of the two species, focusing on an inverted segmental chromosome duplication within linkage group O6 of B. oleracea. Genetic evidence suggests that these segments share a common origin with a region of Arabidopsis chromosome 1. Brassica oleracea and Arabidopsis bacterial artificial chromosome probes have been used for fluorescence in situ hybridization analysis of B. oleracea pachytene chromosomes to further characterize the inverted duplication. This has been highly effective in increasing the local resolution of the cytogenetic map. We have shown that the physical order of corresponding genetic markers is highly conserved between the duplicated regions in B. oleracea and the physical lengths of the regions at pachytene are similar, while the genetic distances are considerably different. The physical marker order is also well conserved between Arabidopsis and B. oleracea, with only one short inversion identified. Furthermore, the relative physical distances between the markers in one segment of B. oleracea and Arabidopsis have stayed approximately the same. The efficacy of using fluorescence in situ hybridization, together with other forms of physical and genetic mapping, for elucidating such issues relating to synteny is discussed.Key words: collinearity, cytogenetic map, pachytene chromosomes, Brassica, Arabidopsis.

Abstract:

Brassica oleracea is an important vegetable species which belongs to the genus Brassica and the mustard family Brassicaceae Burnett. Strong heterosis in B. oleracea is displayed in yield, quality, disease resistance, and stress tolerance. Heterosis breeding is the main way to improve B. oleracea varieties. Male sterile mutants play an important role in the utilization of heterosis and the study of development and regulation in plant reproduction. In this paper, advances in the research and application of male sterility in B. oleracea were reviewed, including aspects of the genetics, cytological characteristics, discovery of genes related to male sterility, and application of male sterility in B. oleracea. Moreover, the main existing problems and prospect of male sterility application in B. oleracea were addressed and a new hybrids’ production strategy with recessive genic male sterility is introduced.

Abstract:

Clubroot disease caused by Plasmodiophora brassicae is a challenge to Brassica crop production. Breakdown of resistance controlled by major genes of the Brassica A genome has been reported. Therefore, identification of resistance in the Brassica C genome is needed to broaden the genetic base of resistance in Brassica napus canola. In this study, we evaluated 135 Brassica oleracea accessions, belonging to eight variants of this species to identify resistant accessions as well as to identify the genomic regions associated with resistance to two recently evolved P. brassicae pathotypes, F3-14 (3A) and F-359-13 (5X L-G2). Resistance to these pathotypes was observed more frequently in var. acephala (kale) followed by var. capitata (cabbage); few accessions also carried resistance to both pathotypes. Association mapping using single nucleotide polymorphism (SNP) markers developed through genotyping by sequencing technique identified 10 quantitative trait loci (QTL) from six C-genome chromosomes to be associated with resistance to these pathotypes; among these, two QTL associated with resistance to 3A and one QTL associated with resistance to 5X L-G2 carried ≥3 SNP markers. The 10 QTL identified in this study individually accounted for 8%–18% of the total phenotypic variance. Thus, the results from this study can be used in molecular breeding of Brassica crops for resistance to this disease.

Abstract:

A specific chloroplast DNA sequence was compared in 34 populations representing 10 wildBrassica species (2n = 18). Species studied were Brassica bourgeaui (Webb) O. Kuntze, Brassica cretica Lam., Brassica hilarionis G.E. Post, Brassica incana Ten., Brassica insularis Moris, Brassica macrocarpa Guss., Brassica montana Pourret, Brassica oleracea L., Brassica rupestris Raf., and Brassica villosa Biv. The sequence was located between the trnL and trnF genes in the large, single-copy region of the chloroplast genome. Site-specific primers were used to amplify the region via the polymerase chain reaction technique. Products of the same size were amplified from all populations. Sequence differences in the DNA fragments were detected by denaturing gradient gel electrophoresis. Ten different haplotypes defined by 20-base sequence differences were detected. Haplotype did not always reflect species classification. Haplotypes were shared by the species pairs B. rupestris - B. villosa, B. cretica - B. incana, and B. bourgeaui - B. oleracea. Populations carrying divergent haplotypes were discovered for B. cretica, B. montana, and B. insularis. Possible introgression of the B. macrocarpa cytoplasm into a B. insularis population was observed. DNA sequences for the 10 haplotypes were determined and subjected to phylogenetic analysis using maximum parsimony. In the phylogenetic tree, the B. rupestris - B. villosa haplotype formed a basal clade, the B. macrocarpa haplotype diverged next, while all other species fell into a third clade.Key words: wild Brassica species, B. oleracea cytodeme, haplotype, cpDNA, phylogeny.

Abstract:

Crop species of Brassica (Brassicaceae) consist of three monogenomic species and three amphidiploid species resulting from interspecific hybridizations among them. Until now, mitochondrial genome sequences were available for only five of these species. We sequenced the mitochondrial genome of the sixth species, Brassica nigra (nuclear genome constitution BB), and compared it with those of Brassica oleracea (CC) and Brassica carinata (BBCC). The genome was assembled into a 232 145 bp circular sequence that is slightly larger than that of B. oleracea (219 952 bp). The genome of B. nigra contained 33 protein-coding genes, 3 rRNA genes, and 17 tRNA genes. The cox2-2 gene present in B. oleracea was absent in B. nigra. Although the nucleotide sequences of 52 genes were identical between B. nigra and B. carinata, the second exon of rps3 showed differences including an insertion/deletion (indel) and nucleotide substitutions. A PCR test to detect the indel revealed intraspecific variation in rps3, and in one line of B. nigra it amplified a DNA fragment of the size expected for B. carinata. In addition, the B. carinata lines tested here produced DNA fragments of the size expected for B. nigra. The results indicate that at least two mitotypes of B. nigra were present in the maternal parents of B. carinata.

Abstract:

The plant U-box (PUB) protein family plays an important role in plant growth and development. The U-box gene family has been well studied in Arabidopsis thaliana, Brassica rapa, rice, etc., but there have been no systematic studies in Brassica oleracea. In this study, we performed genome-wide identification and evolutionary analysis of the U-box protein family of B. oleracea. Firstly, based on the Brassica database (BRAD) and the Bolbase database, 99 Brassica oleracea PUB genes were identified and divided into seven groups (I–VII). The BoPUB genes are unevenly distributed on the nine chromosomes of B. oleracea, and there are tandem repeat genes, leading to family expansion from the A. thaliana genome to the B. oleracea genome. The protein interaction network, GO annotation, and KEGG pathway enrichment analysis indicated that the biological processes and specific functions of the BoPUB genes may mainly involve abiotic stress. RNA-seq transcriptome data of different pollination times revealed spatiotemporal expression specificity of the BoPUB genes. The differential expression profile was consistent with the results of RT-qPCR analysis. Additionally, a large number of pollen-specific cis-acting elements were found in promoters of differentially expressed genes (DEG), which verified that these significantly differentially expressed genes after self-pollination (SP) were likely to participate in the self-incompatibility (SI) process, including gene encoding ARC1, a well-known downstream protein of SI in B. oleracea. Our study provides valuable information indicating that the BoPUB genes participates not only in the abiotic stress response, but are also involved in pollination.

Abstract:

Brassica crops have indeterminate growth and flower over an extended period of time. Harvested seed is therefore comprised of seed of varying degrees of physiological maturity and quality. Using population-based threshold models, broccoli (Brassica oleracea L. Group Italica), brussels sprouts (B. oleracea L. Group Gemmifera), red cabbage (B. oleracea L. Group Capitata), and rapeseed (B. napus L.) were characterized during seed development with respect to sensitivity to abiotic stress (reduced water potential) and shelf life. Using these models our data suggests that the physiological patterns of seed development are the same in all brassica crops we have tested to date. These population-based models can be used to provide a biological basis in which to evaluate cultural, postharvest and storage practices to ensure the production and maintenance of seed vigor.

Abstract:

Ten genome-specific probes were developed from Brassica napus and B. oleracea genomic DNA libraries. Selection was based on polymorphism between and limited variation within genomes, permitting their localization on six individual C-genome chromosomes. Chromosome assignment was accomplished by using two sets of B. campestris – oleracea alien addition lines derived from (i) B. napus and (ii) the artificially synthesized B. napus 'Hakuran'. The presence of shared fragments between A, B, and C genomes indicates partial homology of the three genomes. However, several genome-specific markers could separate these three genomes. Genome-specific clones developed in this study served to confirm the parental diploid species originating the three amphidiploids, B. napus, B. carinata, and B. juncea. At least one clone suggests that B. napus has a polyphyletic origin. These clones were also useful to confirm the close evolutionary proximity among wild species in the B. oleracea cytodeme; however, no clear trends were found to suggest specific wild ancestors for the different B. oleracea horticultural types. Brassica oxyrrhina was distinct from other n = 9 species with most clones tested.Key words: restriction fragment length polymorphism, DNA marker, chromosome addition lines, Brassica oleracea cytodeme, amphidiploids, genome-specific markers.

Abstract:

Wide hybridization between crop brassicas and their wild relatives is an important approach towards increasing the genetic variability, which can be utilised for brassica breeding programs. A new intergeneric hybrid between Erucastrum cardaminoides and Brassica oleracea var. alboglabra was produced using embryo rescue techniques. The F1 hybrid was intermediate between the male and female parent for most of the morphological characters. Cytological studies of pollen mother cells of the hybrid revealed a preponderance of univalents at metaphase I. The number of bivalents in the digenomic hybrid was lower than expected. However, the presence of trivalent and quadrivalent in cells indicated some homoeology between the two genomes and hence the possibility of introgression of genes into the cultivar. The first backcross progeny was obtained using B. oleracea var. alboglabra as the pollen parent. Further, it is being used for developing new alloplasmic lines. The intergeneric hybrid was also used as bridge species to transfer wild (E. cardaminoides) cytoplasm to B. napus and B. carinata. The new intergeneric hybrid and bridge cross hybrids produced in the present investigation have contributed towards increasing the genic and cytoplasmic variability and thus broadening the genetic base of crop brassicas.

DIVERSITY OF SUPRESSIVE LAND MICROFLORA IN CONTROL OF PALLDER DISEASE IN CUBES PLANT (BRASSICA OLERACEA L.)Cabbage (Brassica oleracea L.) was a vegetable crops cultivated in the highlands to meet the needs of the community vegetable. The main obstacle was the cultivation of cabbage root disease outbreak mace (clubroot), which until now have not found an effective control techniques. Clubroot disease caused by organisms that resemble fungi: Plasmodiophora brassicae Wor. which was the soil inhibitant and soil borne pathogen. Therefore, there must be a way to control environmentally friendly by using suppressive soil, find microbes antagonists related to the cabbage plant habitat in the soil. The results showed that the index of diversity both on suppressive and conducive soil of 1.2304 and 1.2811 respectively, and the index of dominance on the suppressive and conducive soil were 0.6677 and 0.6838. Prevalence micoflora of the suppressive soil amounted to 44.22 % and 43.06 % conducive soil all dominated by Fusarium spp. Microbial antagonist as a potential control of P. brassicae was Trichoderma sp. Based on the analysis in the suppressive soil as much as 171 x 103 cfu /g soil, higher than on the conducive soil to 90 x 103 cfu /g soil.

Abstract:

Using fluorescence in situ hybridization, we located ribosomal DNA loci on prometaphase chromosomes of the diploid species Brassica rapa and Brassica oleracea and their amphidiploid Brassica napus. Based on comparisons of chromosome morphology and hybridization patterns, we characterized the individual B. napus rDNA loci according to their presumed origins in the Brassica A and C genomes. As reported in other studies, the sum of rDNA loci observed on B. rapa (AA genome) and B. oleracea (CC genome) chromosomes was one greater than the total number of loci seen in their amphidiploid B. napus (AACC). Evidence is presented that this reduction in B. napus rDNA locus number results from the loss of the smallest A genome rDNA site in the amphidiploid.Key words: Brassica, fluorescence in situ hybridization, ribosomal DNA, rDNA.

Abstract:

A genetic linkage map consisting of 399 RFLP-defined loci was generated from a cross between resynthesized Brassica napus (an interspecific B. rapa × B. oleracea hybrid) and "natural" oilseed rape. The majority of loci exhibited disomic inheritance of parental alleles demonstrating that B. rapa chromosomes were each pairing exclusively with recognisable A-genome homologues in B. napus and that B. oleracea chromosomes were pairing similarly with C-genome homologues. This behaviour identified the 10 A genome and 9 C genome linkage groups of B. napus and demonstrated that the nuclear genomes of B. napus, B. rapa, and B. oleracea have remained essentially unaltered since the formation of the amphidiploid species, B. napus. A range of unusual marker patterns, which could be explained by aneuploidy and nonreciprocal translocations, were observed in the mapping population. These chromosome abnormalities were probably caused by associations between homoeologous chromosomes at meiosis in the resynthesized parent and the F1 plant leading to nondisjunction and homoeologous recombination.Key words: genetic linkage map, homoeologous recombination, Brassica rapa, Brassica oleracea, genome organization.

Abstract:

Vegetable growing is one of the most important and, at the same time, the most complex plant growing branches of agriculture in Ukraine. Firstly, this is due to the value and irreplaceability of vegetable products for human nutrition, which determines the spread of vegetable crops in all regions of the country and the allocation of large areas of agricultural land for their cultivation. On the other hand, a feature of the industry is low transportability and high labor intensity of vegetable production, a large set of cultivated vegetable crops and the mechanization of individual production processes of their cultivation, in particular harvesting, is complicated. Therefore, it is very important to expand better than the cultivation of new vegetable crops, the cultivation areas of which are currently relatively small. One of these crops is Brussels sprouts, which is characterized by excellent nutritional and medicinal properties, but whose cultivation areas are insignificant, due to insufficient study of the characteristics of crop cultivation. Brussels sprouts (Brassica oleracea var. Gemmifera) - vegetable crop. Traditionally regarded as a variety of the species Cabbage (Brassica oleracea) of the genus Cabbage (Brassica) of the Cabbage family (Brassicaceae), some modern sources do not consider Brussels sprouts as an independent species, but consider it a group of varieties of the species Brassica oleracea L., with this approach, the correct name of this group considered Brassica oleracea Gemmifera Group. Keywords: brussels sprouts, variety studies, hybrid, vegetable growing, seed, growing season, shoots.
