Plays a role in abscisic acid (ABA) and salt stress response. May regulate the salt stress response independently of well-characterized pathways (PubMed:24164720). Does not function as cytokinin hydroxylase in yeast heterologous system (Probable). Highly expressed in rosette leaves and siliques, and at lower levels in flowers. By salt stress. No visible phenotype under normal growth conditions, but mutant plants show increased sensitivity to abscisic acid (ABA) treatment or salt stress. Belongs to the cytochrome P450 family.
