Phylogenetic analysis of PIN auxin transporters of nine representative plant species. (A) Phylogenetic analysis of nine representative species. (B) Number of PIN genes in the nine plant species. (C) Phylogenetic relationships of the PINs. The phylogenetic tree was constructed in MEGA 5.0 software using the neighbor-joining (NJ) method. The seven subfamilies of the PINs are represented by different colors. Numbers on the branches are bootstrap proportions of 1000 replicates.
