The determinants of recognition specificity of self-incompatibility in Brassica are SRK in the stigma and SP11/SCR in the pollen, both of which are encoded in the S locus. The nucleotide sequence analyses of many SRK and SP11/SCR alleles have identified several interspecific pairs of S haplotypes having highly similar sequences between B. oleracea and B. rapa. These interspecific pairs of S hap...
The species Brassica oleracea includes several agricultural varieties characterized by the proliferation of different types of meristems. Using a combination of subtractive hybridization and PCR (polymerase chain reaction) techniques we have identified several genes which are expressed in the reproductive meristems of the cauliflower curd (B. oleracea var. botrytis) but not in the vegetative me...
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 دسیزیمنس بر متر) با دو نوع نمک کلریدسدیم و کلریدکلسیم در آب آبیاری...
چکیده: آلودگی خاک خطرات روز افزونی برای سلامتی انسان و محیط زیست دارد، فلزات سنگین از جمله مهم ترین آلاینده های محیط زیست به شمار می آیند که در دهه های اخیر به شدت مورد توجه تعداد زیادی از پژوهشگران قرار گرفته اند. گیاه پالایی یکی از روشهای مقرون به صرفه ای است که می تواند به خروج این عناصر از خاک کمک کند.
Chromosome doubling of microspore-derived plants is an important factor in the practical application of microspore culture technology because breeding programs require a large number of genetically stable, homozygous doubled haploid plants with a high level of fertility. In the present paper, 29 populations of microspore-derived plantlets from cabbage (Brassica oleracea var. capitata) and brocc...
Brassica napus (AACC, 2n = 38), an oil crop of world-wide importance, originated from interspecific hybridization of B. rapa (AA, 2n = 20) and B. oleracea (CC, 2n = 18), and has six FLOWERING LOCUS T (FT) paralogues. Two located on the homeologous chromosomes A2 and C2 arose from a lineage distinct from four located on A7 and C6. A set of three conserved blocks A, B and C, which were found to b...
A population of 150 doubled haploid lines of rapid cycling Brassica oleracea, derived from an F1 from a var. alboglabra x var. italica cross, was scored for flowering time in two trials. Using information on 82 mapped molecular markers, spread evenly across the nine linkage groups, QTL were identified at six locations; one each on linkage groups O2 and O3 and two each on linkage groups O5 and O...
Several species from the Brassica genus are very important agricultural crops in different parts of the world and are also known to be heavy metal accumulators. There have been a large number of studies regarding the tolerance, uptake and defense mechanism in several of these species, notably Brassica juncea and B. napus, against the stress induced by heavy metals. Numerous studies have also be...
Selective increase of the potential anticarcinogen 4-methylsulphinylbutyl glucosinolate in broccoli.
The putative anticarcinogenic activity of Brassica vegetables has been associated with the presence of certain glucosinolates. 4-Methylsulphinylbutyl isothiocyanate (sulphoraphane), derived from the corresponding glucosinolate found in broccoli, has previously been identified as a potent inducer of the anticarcinogenic marker enzyme quinone reductase [NADP(H):quinone-acceptor oxidoreductase] in...
An Illumina Infinium array comprising 5306 single nucleotide polymorphism (SNP) markers was used to genotype 175 individuals of a doubled haploid population derived from a cross between Skipton and Ag-Spectrum, two Australian cultivars of rapeseed (Brassica napus L.). A genetic linkage map based on 613 SNP and 228 non-SNP (DArT, SSR, SRAP and candidate gene markers) covering 2514.8 cM was const...
