Expressed in roots and leaves. Leaves exhibit a diurnal pattern of expression with up-regulation in the morning, followed by a midday maximum and a 2.5 fold down-regulation in the evening. Expression in leaves is unaffected by salinity or dehydration stress but is induced by mannitol. Mannitol application, salinity and dehydration stress rapidly induce expression in roots. Phosphorylated in vitro by CK2. Belongs to the plant dehydrin family.
