Alignments of derived amino-acid sequences of PBR1 homologs. Amino-acid sequences of AtPBR1 (At1g71720), GmPBR1 (GenBank accession number: XP_003535559), SlPBR1 (XP_004253265), ZmPBR1 (DAA58739), BdPBR1 (XP_003569284) and OsPBR1 (NP_001043440) were aligned as described in Materials and Methods. Identical amino-acid residues and conservative changes were depicted in black and grey background, respectively. Two S1 domains were labeled.
