LEA — Lactuca sativa

Summary

LsLEA (LSAT_V11C200078240) on chromosome 2 of garden lettuce encodes a dehydrin family protein with phosphatidylglycerol, phosphatidylserine, phosphatidate, phosphoinositide, and lipid binding activities. The gene is associated with cellular responses to desiccation, drought, salt, cold, abscisic acid, wounding, and light stimulus, as well as cold acclimation, embryogenesis, ABA signaling, and defence response to fungi. It localises to the vesicle membrane, membrane, cytosol, cytoplasm, and nucleus. Associations with transpiration rate, photosynthetic rate, chlorophyll content, salt tolerance, freezing and cold stress tolerance, seedling establishment, drought response, osmotic stress tolerance, and membrane stability have been reported. Studies of related genes in other species link the family to drought tolerance, salt tolerance, ABA sensitivity, osmotic stress response, and traits including raffinose content, cell membrane stability, leaf water potential, and seed dormancy.
