LEA — Daucus carota subsp. sativus

Summary

DCAR_017311, designated DcLEA on carrot chromosome 5, encodes a dehydrin family protein with a conserved dehydrin signature domain. The product binds lipids, including phosphatidylglycerol, phosphatidylserine, phosphatidate, and phosphoinositides, as well as metals. In carrot, DcLEA is associated with desiccation tolerance acquisition, cellular responses to desiccation, salt, drought, and light, cold acclimation, somatic embryogenesis, seed development, wounding, and sucrose transport. It localizes to the vesicle membrane, cytosol, cytoplasm, and nucleus. The gene is linked to callus induction, seed maturation, photosynthetic rate, freezing and cold tolerance, seedling establishment, drought and salt stress tolerance, osmotic stress tolerance, membrane stability, and ABA response. Studies of related genes in other species connect the family to drought tolerance, ABA signaling, hydrogen peroxide accumulation, and low-temperature response.
