The genus Brassica includes several important agricultural and horticultural crops. Their current genome structures were shaped by whole-genome triplication followed by extensive diploidization. The availability of several crucifer genome sequences, especially that of Chinese cabbage (Brassica rapa), enables study of the evolution of the mesohexaploid Brassica genomes from their diploid progeni...
Development, longevity, survivorship and fecundity of the alate and apterous forms of the turnip aphid, Lipaphis erysimi (Kaltenbach), were studied on cabbage under constant temperatures in the laboratory. The developmental durations for alate nymphs were 15.8, 9.5, 8.0 and 5.4 d at 15, 20, 25 and 30 ° C, respectively, and those for apterous nymphs were 13.9, 6.8, 6.1 and 5.0 d. Alate nymphs de...
Onion thrips (Thrips tabaci Lindeman) has become a significant pest of cabbage (Brasssica oleracea L.) in regions with a dry continental climate. Thrips-resistant cabbage varieties have been developed in breeding programs, but the mechanisms ofresistance remain largely unknown. Antixenosis, one of the three resistance mechanisms, may play a role but no plant trait has been identified as a sourc...
The main problems with Bacillus thuringiensis products for pest control are their often narrow activity spectrum, high sensitivity to UV degradation, and low cost effectiveness (high potency required). We constructed a sporulation-deficient SigK(-) B. thuringiensis strain that expressed a chimeric cry1C/Ab gene, the product of which had high activity against various lepidopteran pests, includin...
هدف از این تحقیق بررسی اثر آبیاری با دو نوع آب شور حاوی کلریدسدیم و کلریدکلسیم و کاربرد عنصر روی در خاک آلوده به کادمیوم بر خصوصیات رشدی و غلظت کادمیوم در کلم قمری(brassica olerace var. gongylodes) است. این آزمایش در قالب طرح کاملاً تصادفی با آرایش فاکتوریل با سه تکرار انجام شد. تیمارهای آزمایشی شامل سه سطح شوری آب (صفر، 5/2 و 5 دسی زیمنس بر متر) با دو نوع نمک کلریدسدیم و کلریدکلسیم در آب آبیاری...
Scharakteryzowano wybrane gatunki warzyw należące do rodzaju Brassica: kapusta głowiasta biała (Brassica oleracea L. var. capitata f. alba), włoska sabauda L.), pekińska rapa subsp. pekinensis), brokuł(Brassica italica), jarmuż sabellica kalafior botrytis kalarepa gongylodes brukselska gemmifera). Opisano prozdrowotne właściwościlecznicze, znaczenie gospodarcze, a także przedstawiono ich jako s...
Yellow-seed (i.e., yellow seed coat) is one of the most important agronomic traits of Brassica plants, which is correlated with seed oil and meal qualities. Previous studies on the Brassicaceae, including Arabidopsis and Brassica species, proposed that the seed-color trait is correlative to flavonoid and lignin biosynthesis, at the molecular level. In Arabidopsis thaliana, the oxidative polymer...
Stir-frying is a cooking method, originating from Asia, in which food is fried in small amount of very hot oil. Nowadays in many other parts of the world stir-frying is a very popular method to prepare vegetables, because it is fast and fried vegetables are tasty. However, the retention of phytochemicals like the health-beneficial glucosinolates in Brassica vegetables is less explored for stir-...
In plants, flowering is the most important transition from vegetative to reproductive growth. The flowering patterns of monocots and eudicots are distinctly different, but few studies have described the evolutionary patterns of the flowering genes in them. In this study, we analysed the evolutionary pattern, duplication and expression level of these genes. The main results were as follows: (i) ...
We cloned a major aliphatic glucosinolate (GSL) gene, BoGSL-ELONG in Brassica oleracea, using the Arabidopsis sequence database. We based our work on an Arabidopsis candidate gene forming part of a gene family coding for isopropyl malate synthetase-like enzymes (IPMS). This gene is presumably responsible for synthesis of GSL possessing side chains consisting of four carbons (4C). The similarity...
