HAN-domain containing B-GATAs from Arabidopsis and rice. (A) Schematic representation of B-GATAs with an N-terminal HAN-domain. The HAN-domain of Arabidopsis GATA29 is degenerate and apparent orthologs of GATA29 cannot be retrieved in rice. Boxes represent protein regions with sequence similarity (gray) or high sequence conservation (black), lines represent protein regions with restricted sequence conservation. (B) Sequence alignment of the HAN-domain and the GATA-domain of HAN-domain containing B-GATAs from Arabidopsis and rice. The presence of the HAN-domain can already be predicted based on the sequence of the GATA domain. Conserved amino acids that allow distinguishing HAN-domain B-GATAs from other B-GATAs are marked with arrowheads. The asterisks mark residues in the HAN-domain as identified in loss-of-function mutant alleles of HAN family members providing evidence for the functional importance of this protein domain for protein function (Whipple et al., 2010; Kanei et al., 2012).
