Involved in stress response (By similarity). Does not function as cytokinin hydroxylase in yeast heterologous system (Probable). Highly expressed in siliques and at lower levels in flowers and rosette leaves. By salt stress. No visible phenotype under normal growth conditions. Belongs to the cytochrome P450 family. It is uncertain whether Met-1 or Met-56 is the initiator. Truncated N-terminus. Truncated N-terminus.
