LEA — Daucus carota subsp. sativus

Summary

DCAR_021479, designated DcLEA on carrot chromosome 6, encodes a dehydrin family protein characterised by a Dehydrin_CS domain and annotated with lipid, phosphoinositide, phosphatidylglycerol, phosphatidylserine and phosphatidate binding activities. In carrot, DcLEA is associated with acquisition of desiccation tolerance, cellular responses to desiccation, salt, drought, light stimulus, wounding and 1-aminocyclopropane-1-carboxylic acid, as well as cold acclimation, somatic embryogenesis, seed development, syngamy, sucrose transport, protein denaturation and NO storage. The protein localises to the vesicle membrane, membrane, cytosol, cytoplasm and nucleus. DcLEA has been linked to freezing and cold stress tolerance, drought and dehydration responses, salt and osmotic stress tolerance, membrane stability, seedling establishment, callus induction, seed maturation, photosynthetic rate, and abscisic acid responses. Studies of related genes in other species connect the family to drought tolerance, salt tolerance, ABA signalling, low temperature response and osmotic stress response.
