Sequences of nuclear chalcone synthase gene (Chs) were analyzed for species of the Brassicaceae family to reconstruct phylogenetic relationships The phylogeny for 106 species of 60 genera was reconstructed and assigned to 24 tribes using maximum parsimony maximum likelihood and neighbor-joining methods Most of the tribes can be assigned to the major lineages (Lineages I-III) suggested by Beilstein et al (2006) The tribe Camelineae was not monophyletic Conringia planisiliqua together with Orychophragmus violaceus would not be recognized as a new tribe proposed by the previous studies and C planisiliqua should be a member of tribe Isatideae The genera delimitation and monophyly of the expanded Solms laubachia were also confirmed by our data Furthermore one parent of inter-tribal allopolyploid Pachycladon appeared to be most closely associated with Crucihimalaya Transberingia and tribes Boechereae and Halimolobeae another parent was proved to be in tribe Smelowskieae (C) 2010 Elsevier Ltd All rights reserved
