Phylogenetic analysis of NF-Y proteins in Brassica campestris, rice, Arabidopsis, and chromosomal localization of BcNF-Y. (a) Unrooted neighbor-joining phylogenetic tree of NF-Y in flowering Chinese cabbage, Arabidopsis, and rice. The phylogenetic tree is divided into three subfamilies, and different colors are used to distinguish members of each subfamily. (b) Chromosomal distribution of 49 BcNF-Y genes in flowering Chinese cabbage.
