The origin and evolution of a hybrid species complex in the genus Brassica (cabbage, turnip, mustard, rapeseed oil) has been explored through mutational analysis of the maternally inherited chloroplast genome. A detailed chloroplast DNA phylogeny enables identification of the maternal parent for most of the amphidiploids examined and permits quantitative resolution of the relative time of hybridization as well as the relative divergence of the diploid parents. Contradictory chloroplast and… CONTINUE READING
