Abstract

Brassicaceae (crucifers or the mustard family) is a large plant family comprising over 330 genera and about 3,700 species, including several important crop plants (e.g. Brassica species), ornamentals as well as model organisms in the plant sciences (e.g. Arabidopsis thaliana). In recent years, the wealth of Arabidopsis and Brassica genomic resources along with newly established tools and techniques fostered the unprecedented progress in phylogenetics and genomics of crucifers. Multigene phylogenetic analyses paved the way for a new infrafamiliar classification based on phylogenetically circumscribed genera and tribes. A new generation of comparative genetic, cytogenetic, and genomic studies as well as whole-genome sequencing projects unveil general principles of karyotype and genome evolution in Brassicaceae.
