Phylogenetic analysis of GIGANTEA (GI), CONSTANS-LIKE (COL), FLOWERING LOCUS T (FT), and SUPPRESSOR OF OVEREXPRESSION OF CONSTANS 1 (SOC1) protein sequences in different plants. Phylogenetic analysis was performed using the neighbor-joining method by MEGA5.0. (A) The phylogenetic tree of GI/GI-like protein sequences was divided into three groups.
