LEA — Daucus carota subsp. sativus

Summary

DCAR_024077, designated DcLEA, encodes a dehydrin family protein characterised by a dehydrin conserved sequence (Dehydrin_CS). In carrot, this gene is associated with the acquisition of desiccation tolerance, cold acclimation, response to abscisic acid, somatic embryogenesis, seed development, and defence response to fungi. It has also been linked to protein denaturation, sucrose transport, and syngamy. The protein localises to the membrane, cytosol, cytoplasm, and nucleus. DcLEA is associated with freezing stress tolerance, cold tolerance, drought response, salt stress tolerance, osmotic stress tolerance, and membrane stability. Additional associations include callus induction, seed maturation, photosynthetic rate, and seedling establishment. Studies of related genes in other species link the family to drought tolerance, salt tolerance, ABA sensitivity, osmotic stress response, and traits such as water use efficiency, seed dormancy, and germination rate.
