Phylogenetic analysis of LAXs (A) and ABCBs (B) auxin transporter protein families from rice, Arabidopsis, sorghum, and maize. The protein sequences of sorghum and maize were retrieved from Phytozome (v10.3) based on recent publications (Shen et al., 2010; Yue et al., 2015). The phylogenetic trees were constructed using Mega5.2 program (Tamura et al., 2011).
