A detailed comparative map of Brassica oleracea and Arabidopsis thaliana has been established based largely on mapping of Arabidopsis ESTs in two Arabidopsis and four Brassica populations. Based on conservative criteria for inferring synteny, "one to one correspondence" between Brassica and Arabidopsis chromosomes accounted for 57% of comparative loci. Based on 186 corresponding loci detected i...

Self-incompatibility (SI) in the Brassicaceae plant family is controlled by the SRK and SCR genes situated at the S locus. A large number of S haplotypes have been identified, mainly in cultivated species of the Brassica and Raphanus genera, but recently also in wild Arabidopsis species. Here, we used DNA sequences from the SRK and SCR genes of the wild Brassica species Brassica cretica, togeth...

BACKGROUND Oilseed Brassica represents an important group of oilseed crops with a long history of evolution and cultivation. To understand the origin and evolution of Brassica amphidiploids, simple sequence repeat (SSR) markers were used to unravel genetic variations in three diploids and three amphidiploid Brassica species of U's triangle along with Eruca sativa as an outlier. RESULTS Of 124...

ObjectiveThis study was initiated to investigate the effect of Portulaca oleraceae on morphine dependence in mice.Materials and MethodsDependence was induced using the subcutaneous injections of morphine for 3 days. On the day 4, morphineinjected 2 h prior to intraperitoneal injection of naloxone. The plant extracts ethanolic or aqueousadministered 0.5 h before the final dose of morphine. The n...

BRASSICA GENOME RESEARCH TOPIC Brassica species include important crops and provide unique materials for the study of genome evolution. These crops include six important vegetables and oilseed crops, which have been classically described by “U’s triangle’. The three diploid species B. rapa (A genome), B. nigra (B genome), and B. oleracea (C genome) have formed the amphidiploid species B. juncea...

OBJECTIVE Brassica vegetable consumption (e.g. broccoli) leads to excretion of isothiocyanates (ITC) in urine. We evaluated the consistency of ITC as a biomarker for dietary Brassica vegetable consumption across the types of vegetables and methods of preparation used in Western societies, and across consumption levels. DESIGN A single-armed behavioural intervention with duplicate baseline ass...

A complete genome sequence provides unlimited information in the sequenced organism as well as in related taxa. According to the guidance of the Multinational Brassica Genome Project (MBGP), the Korea Brassica Genome Project (KBGP) is sequencing chromosome 1 (cytogenetically oriented chromosome #1) of Brassica rapa. We have selected 48 seed BACs on chromosome 1 using EST genetic markers and FIS...
