Arabidopsis thaliana, a member of the family Brassicaceae, is the most widely studied model system in plants. We completed a comprehensive chloroplast phylogeny for the Brassicaceae that, in combination with candidate genes known from Arabidopsis thaliana, makes the Brassicaceae a unique system for addressing evolutionary questions. In particular, phylogenetic results indicate that epidermal hairs (trichomes), which have been used to delineate taxa in the family, have a complex pattern of evolution. We compared phylogenetic results with SEM of mature trichome form as an initial phase of comparative trichome morphogenesis.
