The Brassicaceae then and now: advancements in the past three decades, a review

Abstract Background and Aims The Brassicaceae and many species of its various genera are currently recognized as models in various fields of biology. The impact of the major advancements in molecular phylogeny, development, genomics and related fields on the systematics of the family led to the recognition of the first phylogenetic tribal classification of the family and recognition of monophyletic genera. The present review is aimed to cover almost all advancements in the family systematics for the first time. Methods The comprehensive literature on the molecular phylogeny, development, cytology, genomics and related fields was assembled relative to its systematics value to Brassicaceae, especially for tribal classification, generic delimitation, origin, hybridization and migration. Key Results Adjustments to the limits of problematic tribes Brassiceae, Coluteocarpeae and Thelypodieae, in addition to various genera (e.g. Atacama, Delpinophyton, Menonvillea, Noccaea and Pseudoarabidopsis) are discussed and likely solutions suggested. A complete list of apomorphic characters in the family is assembled for the first time, and all species or genera in which they occur are listed. Conclusions This comprehensive review is the first historical advancement of the Brassicaceae systematics during the past three decades, and it aims to help current and future students of the family to understand the background of such developments.
