RD17 — Brassica napus

Summary

BnRD17 (RD17), located on chromosome C05 of oilseed rape (Brassica napus), encodes a dehydrin family protein containing the Dehydrin_CS domain. The gene product is associated with actin binding, transmembrane receptor protein serine/threonine kinase activity, and protein binding. It is linked to responses to abscisic acid, cold, heat, and osmotic stress, as well as to abscisic acid anabolism, hypersensitivity, phloem transport, leaf vascular tissue pattern formation, embryogenesis, regulation of seed germination, heat acclimation, auxin and brassinosteroid signalling, protein phosphorylation, and defence against fungi. The protein localises to the actin cytoskeleton, plasmodesma, membrane, cytosol, plasmalemma, cytoplasm, and nucleus. Associations with leaf vein morphology, salt tolerance, cold acclimation, dehydration tolerance, and drought tolerance have been observed. Studies of related genes in other species link the family to cold acclimation, abscisic acid response, and heat stress response.
