Phylogeny, chromosome number and genome size evolution in Physarieae (Brassicaceae).
Original language description
The Physarieae tribe (Brassicaceae or mustard family), predominately with a base chromosome number of x=8, exhibits a remarkable diversity of haploid chromosome number, thereby suggesting a dynamic rate of chromosomal change. The goal of this research was to study, in a molecular phylogenetic context, the evolution of chromosome number and genome size within the tribe. Our molecular phylogenetic studies were generated with three independent loci (chloroplast ndhF, nrDNA ITS, and LUMINIDEPENDENS 5-7 exons and 5, 6 introns). The results suggest that Physarieae is a monophyletic lineage closest related to the Halimolobeae tribe. Within the tribe, three monophyletic clades are recovered: The NDDLS clade including five genera (Nerisyrenia, Dithyrea, Dimorphocarpa, Lyrocarpa, and Synthlipsis), the Paysonia clade, and the Physaria clade. The phylogenetic findings further suggest that there was a 2-fold genome size expansion after the divergence of Physarieae from closely related tribes (2C =
