Amino acid sequence alignment of the SIZ/PIAS proteins. The deduced amino acid sequence of DnSIZ1 was aligned with the amino acid sequences of SIZ/PIAS homologs from other species. The sequences were obtained from the NCBI protein database using the BLAST network service. Amino acid sequences of SIZ/PIAS proteins from Dendrobium (Dn), Arabidopsis thaliana (At), Oryza sativa (Os), Medicago truncatula (Mt), Glycine max (Gm), Vitis vinifera (Vv), Brachypodium distachyon (Bd), Homo sapiens (Hs), Mus musculus (Mm), Saccharomyces cerevisiae (Sc) and Schizosaccharomyces pombe (Sp). The domains include: the SAP (Scaffold attachment factor A/B/acinus/PIAS); the PHD (Plant homeodomain); the PINIT (Pro-Ile-Asn-Ile-Thr); the SP-RING (SIZ/PIAS-RING); and the SXS (Ser-X-Ser) domain. Black and gray shaded backgrounds indicated amino acids that were identical residues or conservative substitutions, respectively. Hyphens indicated gaps introduced to optimize alignments. Numbers above the alignment indicated the number of the amino acids from the first amino acid
