Evolution of RAD- and DIV-Like Genes in Plants.

ABSTRACT: Developmental genetic studies of Antirrhinum majus demonstrated that two transcription factors from the MYB gene family, RADIALIS (RAD) and DIVIRICATA (DIV), interact through antagonism to regulate floral dorsoventral asymmetry. Interestingly, similar antagonistic interaction found among proteins of FSM1 (RAD-like) and MYBI (DIV-like) in Solanum lycopersicum is involved in fruit development. Here, we report the reconstruction of the phylogeny of I-box-like and R-R-type clades, where RAD- and DIV-like genes belong, respectively. We also examined the homology of these antagonistic MYB proteins using these phylogenies. The results show that there are likely three paralogs of RAD-/I-box-like genes, RAD1, RAD2, and RAD3, which originated in the common a
