Flower power and the mustard bomb: Comparative analysis of gene and genome duplications in glucosinolate biosynthetic pathway evolution in Cleomaceae and Brassicaceae

Abstract

Many GS genes have expanded through polyploidy, gene transposition duplication, and tandem duplication in Cleomaceae. Duplicate retention through these mechanisms is similar to A. thaliana, but based on the expression of GS genes, Cleomaceae-specific diversification of GS genes has taken place.
