Classification of S. tuberosome ARF proteins. (A) Neighbor-joining tree were generated using MEGA 7.0 to determine the phylogenetic relationship between S. tuberosome ARF proteins (left). According to classification proposed by Finet et al. (2013), StARFs were divided into three subgroups: (A–C) Shadow colors were used to distinguish different StARF subgroups. (B) The intron-exon organization of StARF genes was plotted using Gene Structure Display Server (Version 2.0). Blue boxes represent exons, and grey lines represent introns.
