FIGURE 1.

Sequence analysis and the expression patterns of ZmSIZ1a and ZmSIZ1b. (a) Phylogenetic tree of ZmSIZ1 and its Arabidopsis and rice homologues. ZmSIZ1a and ZmSIZ1b are marked with a red dashed rectangle. Five conserved domains in SIZ1 proteins are indicated as boxes and shown on the right. SAP, scaffold attachment factor A/B/acinus/PIAS domain; PHD, plant homeodomain; PINIT, proline‐isoleucine‐asparagine‐isoleucine‐threonine; SP‐RING, SIZ/PIASRING; SXS, serine‐X‐serine. (b) Relative expression levels of ZmSIZ1a and ZmSIZ1b in different tissues
