Abstract excerpt
Domestication imposed radical selection pressures on plants, transforming them into crops that support global populations today. In this study, we investigate the loss of seed dispersal via pod shattering during common bean (Phaseolus vulgaris L.) domestication. We identified PvMYB26 mutations in all three main gene pools of common bean, including an 8 kb deletion in Middle American lines eliminating the gene's...
