E3 Ligases

The HECT-domain protein family is one of the most important classes of E3 ligases. While the roles of this family in human diseases have been intensively studied, the information for plant HECTs is limited. In the present study, we performed the identification of HECT genes in Brassica rapa and Brassica oleracea, followed by analysis of phylogeny, gene structure, additional domains, putative cis-regulatory elements, chromosomal location, synteny, and expression. Ten and 13 HECT genes were respectively identified in B. rapa and B. oleracea and then resolved into seven groups along with their Arabidopsis orthologs by phylogenetic analysis. This classification is well supported by analyses of gene structure, motif composition within the HECT domain and additional protein domains. Ka/Ks ratio analysis showed that these HECT genes primarily underwent purifying selection with varied selection pressures resulting in different rates of evolution. RNA-Seq data analysis showed that the overwhelming majority of them were constitutively expressed in all tested tissues. qRT-PCR based expression analysis of the 10 B. rapa HECT genes under salt and drought stress conditions showed that all of them were responsive to the two stress treatments, which was consistent with their promoter sequence analysis revealing the presence of an important number of phytohormone-responsive and stress-related cis-regulatory elements. Our study provides useful information and lays the foundation for further functional determination of each HECT gene across the Brassica species.

In The Wild

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.

Season Extension

Spunbonded polyester or polystyrene row covers were used as additional cold protection for spinach (Spinacia oleracea), kale (Brassica oleracea), pak choi (Brassica rapa) and P-types of lettuce (Lactuca savita) grown in ground beds under unheated polyethylene tunnels during the fall and winter of 1991 and 1992 in climatic zone 6. Temperatures inside poly tunnels averaged 2.4C warmer than outside. Average temperatures were 1.9C warmer than control under polystyrene and 1.5C warmer under spunbonded polyester. Average hourly temperatures showed both row covers offered significantly more cold protection than the greenhouse covering alone; but the two row covers offered similar protection from the cold. Row covers did not result in fresh weight differences in most of the species tested, except kale which had greater fresh weight in control. It may be concluded that during a similar mild winter, these cool season vegetables could be grown under unheated polyethylene tunnels with no additional protection necessary. When temperatures are lower, row covers could provide the protection required to produce these crops.

Field trials were conducted to evaluate resistance to clubroot (Plasmodiophora brassicae, pathotype 6) in green cabbage (Brassica oleracea var. capitata) and napa cabbage (Brassica rapa ssp. pekinensis) at sites in southern Ontario in 2009 and 2010. The reaction of green cabbage cultivars Kilaton, Tekila, Kilaxy, and Kilaherb and the commercial standard cultivars, Bronco or Atlantis, were evaluated on organic (two site-years) and mineral soils (two site-years) that were naturally infested with the clubroot pathogen. In addition, fluazinam fungicide was drench applied to one treatment of the commercial standard cultivar immediately after transplanting. The napa cabbage cultivars Yuki, Deneko, Bilko, and Mirako (in 2009) and Emiko, Mirako, Yuki, and China Gold (in 2010) were evaluated only on organic soils (two site-years). At harvest, the roots of each plant were assessed for clubroot incidence and severity. Also, plant and head characteristics of the resistant green cabbage cultivars were evaluated at one site in 2010. The green cabbage cultivars Kilaton, Tekila, Kilaxy, and Kilaherb were resistant to pathotype 6 (0% to 3.8% incidence), but ‘Bronco’ was susceptible (64% to 100% incidence). Application of fluazinam reduced clubroot severity on ‘Bronco’ by 6% at one of three sites. Resistance was more effective in reducing clubroot than application of fluazinam. Plant and head characteristics of the resistant cultivars were similar to those of ‘Bronco’ treated with fluazinam. Napa cabbage cultivars Yuki, Deneko, Bilko, Emiko, and China Gold were resistant to clubroot (0% to 13% incidence), and ‘Mirako’ was highly susceptible (87% to 92% incidence). We conclude that the clubroot resistance available in several cultivars of green and napa cabbage was effective against P. brassicae pathotype 6.

Opisano prozdrowotne właściwościlecznicze, znaczenie gospodarcze, a także przedstawiono znaczenie ich jako surowca dla przemysłu spożywczego i farmaceutycznego. Warzywa kapustne charakteryzują się wysoką zawartością witamin i minerałów, zawierają wiele cennych właściwości leczniczych. Posiadają wysoką wartość odżywczą, dużą aktywność przeciwutleniajacą, a także wykazują działanie prozdrowotne. Z żywieniowego punktu widzenia warzywa należące do rodziny kapustowatych są postrzegane jako produkty o dużym znaczeniu w profilaktyce nowotworowej. Na szczególną uwagę zasługuje jarmuż (Brassica oleracea L. var. acephala), który charakteryzuje się wysokimi walorami odżywczymi i prozdrowotnymi, a jednocześnie jest warzywem mało popularnym w Polsce.
