Figure 1

Amino acid sequence alignment and phylogenetic analysis. (A) Structure analysis and amino acid multi-alignment of the nucleotide-binding domains (NBD) of ABCG proteins from different plant species. ABCG domains are marked as two green and orange blocks. TMD, transmembrane domain; Walker A, ATP-binding cassette (ABC) signature; Walker B, NBD associated motifs. Blue indicates identical amino acids; pink indicates similar amino acids. (B) Phylogenetic analysis of ABCG proteins from Populus trichocarpa (PtoABCG36, MH660448); Arabidopsis thaliana (AtABCG36, NP_176196); Oryza sativa (OsABCG36, XP_015648358; OsABCG37, XP_015648329; OsABCG43, XP_015646575; OsABCG44, XP_015650488); Glycine Max (GmABCG36, XP_006585572); Ricinus conmunis (RcABCG36, XP_002515970); and Vitis vinifera (VvABCG29, XP_010654625); Gossypium arboretum (GaABCG36, XP_017606959). The numbers beside the branches represent bootstrap values based on 1000 replications.
