Phylogenetic relationships, conserved motifs, and amino acid sequence alignment of subclass III SnRK2s in maize, rice and Arabidopsis. (A) Phylogenetic tree and conserved motifs analysis of subclass III SnRK2s family in maize, rice and Arabidopsis. (B) Amino acid sequence alignment of the subclass III SnRK2 proteins in maize, rice and Arabidopsis. Domain III is responsible for osmotic stress response, and domain IV functions in ABA stress response
