Retention of triplicated phytoene synthase (PSY) genes in Brassica napus L. and its diploid progenitors during the evolution of the Brassiceae.

Abstract excerpt

The extent of genome redundancy exhibited by Brassica species provides a model to study the evolutionary fate of multi-copy genes and the effects of polyploidy in economically important crops. Phytoene synthase (PSY) catalyzes the first committed reaction of the carotenoid biosynthetic pathway, which has been shown to be rate-limiting in Brassica napus seeds. In Arabidopsis thaliana, a single PSY gene (AtPSY)...
