LEA — Daucus carota subsp. sativus

Summary

DCAR_028967 (DcLEA) on carrot chromosome 9 encodes a dehydrin family protein with a conserved dehydrin signature, annotated for phosphatidylglycerol, phosphatidylserine, phosphatidate, phosphoinositide and lipid binding, as well as metal binding. The gene 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. It is linked to vesicle membrane, membrane, cytosol, cytoplasm and nucleus localisation. Associations include freezing stress tolerance, cold tolerance, drought response, salt and osmotic stress tolerance, seedling establishment, membrane stability, callus induction, seed maturation and photosynthetic rate. Studies of related genes in other species link the family to drought stress resistance, ABA sensitivity and hydrogen peroxide accumulation.
