Phylogenetic analysis of PIN auxin transporter of 19 plant species. The putative full-length amino acid sequences of PIN genes were aligned by ClustaXI (2.1) with a partial EST-based PIN sequence of Klebsormidiophyceae (Streptophyte algae). Neighbor-joining tree was constructed by Mega7 with the statistical parameters using poisson model, and pairwise deletions. Accession numbers of the PIN proteins were listed in Additional file: Table S1. The 155 PIN proteins from 19 plant species can be classified into 14 distinct clades and differentiated in color. Different lineages were distinguished by several geometric shapes with hollow or solid. The bootstrap values with 1000 replicates were placed on the nodes.
