Expansion and Functional Divergence of the SHORT VEGETATIVE PHASE (SVP) Genes in Eudicots.

ABSTRACT: SHORT VEGETATIVE PHASE (SVP) genes are members of the well-known MADS-box gene family that regulates vital developmental processes in plants. In Arabidopsis, there are two SVP paralogs, SVP/AGAMOUS-LIKE22 (SVP/AGL22) and AGL24. SVP protein suppresses the flowering process, whereas AGL24 acts as a flowering activator. Phylogenetic analysis of SVP genes representing most of the sequenced eudicot species showed that the SVP gene family could be divided into three major clades in eudicots (SVP1, SVP2, and SVP3), most likely resulting from an ancient whole-genome triplication in core eudicots. Among them, the SVP1 (SVP) and SVP2 (AGL24) clades are retained in nearly all species, whereas the SVP3 clade has been lost in Brassicaceae, Myrtaceae, and some species in other families.
