Background: In plant breeding program to produce hybrid varieties, pair of male sterile and restorer fertility lines are required. Differentiation of lines possessing restorer fertility allele from the lines lacking it remove the need for the progeny test, and thus reducing the time and the cost in the hybrid production procedure. Canola breeding program in Iran has concentrate...
The Brassica rapa line RLR22 was resistant to eight diverse turnip mosaic virus (TuMV) isolates. A B. rapa genetic map based on 213 marker loci segregating in 120 first back-cross (B(1)) individuals was established and aligned with the B. rapa genome reference map using some of the RFLP probes. B(1) individuals were self-pollinated to produce B(1)S(1) families. The existence of two loci control...
The paleohexaploid crop Brassica rapa harbors an enormous reservoir of morphological variation, encompassing leafy vegetables, vegetable and fodder turnips (Brassica rapa, ssp. campestris), and oil crops, with different crops having very different leaf morphologies. In the triplicated B. rapa genome, many genes have multiple paralogs that may be regulated differentially and contribute to phenot...
Experiments were conducted to evaluate the nutritional value of meal derived from low glucosinolate cultivars of mustard (Brassica juncea) in comparison to samples of canola meal (Brassica napus, Brassica rapa). Samples of Brassica seed (four B. juncea, one B. napus, and one B. rapa) were processed using laboratory procedures to produce oil-extracted meals, which were examined for composition (...
The Brassica genus comprises many economically important worldwide cultivated crops. The well-established model of the Brassica genus, U's triangle, consists of three basic diploid plant species (Brassica rapa, Brassica oleracea, and Brassica nigra) and three amphidiploid species (Brassica napus, Brassica juncea, and Brassica carinata) that arose through interspecific hybridizations. Despite be...
Aliphatic glucosinolates are the predominant sulfur-rich plant secondary metabolites in economically important Brassica crops. Glucosinolates and their hydrolysis products are involved in plant-microbe, plant-insect, plant-animal, and plant-human interactions. It is, therefore, important to manipulate glucosinolate profiles and contents in Brassica species. In this study, aliphatic glucosinolat...
We constructed a high-density Brassica rapa integrated linkage map by combining a reference genetic map of 78 doubled haploid lines derived from Chiifu-401-42 × Kenshin (CKDH) and a new map of 190 F2 lines derived from Chiifu-401-42 × rapid cycling B. rapa (CRF2). The integrated map contains 1017 markers and covers 1262.0 cM of the B. rapa genome, with an average interlocus distance of 1.24 cM....
The mapping and functional analysis of quantitative traits in Brassica rapa can be greatly improved with the availability of physically positioned, gene-based genetic markers and accurate genome annotation. In this study, deep transcriptome RNA sequencing (RNA-Seq) of Brassica rapa was undertaken with two objectives: SNP detection and improved transcriptome annotation. We performed SNP detectio...
Brassica rapa, which is closely related to Arabidopsis thaliana, is an important crop and a model plant for studying genome evolution via polyploidization. We report the current understanding of the genome structure of B. rapa and efforts for the whole-genome sequencing of the species. The tribe Brassicaceae, which comprises ca. 240 species, descended from a common hexaploid ancestor with a bas...
objectives: turnip leaf has been used in folk medicine of iran for the treatment of diabetes. however,so far no scientific study has been done to support its use in traditional medicine. the present study was carried out to evaluate the possible hypoglycemic efficacy of aqueous extract of turnip leaf (aetl) in diabetic rats. materials and methods: alloxan-induced diabetic rats were orally treat...
