LEA — Lactuca sativa

Summary

LsLEA on chromosome 3 of garden lettuce (Lactuca sativa) encodes a dehydrin family protein containing the Dehydrin_CS domain and is annotated with lipid, phosphoinositide, phosphatidylglycerol, phosphatidylserine, phosphatidate and metal binding activities. The gene is associated with responses to abscisic acid, desiccation, drought, salt, cold, wounding, light stimulus, mannitol, 1-aminocyclopropane-1-carboxylic acid, and defence against fungi, as well as cold acclimation, embryogenesis, and ABA signalling. It localises to the vesicle membrane, membrane, cytosol, cytoplasm and nucleus. Associations with agronomic traits include transpiration rate, photosynthetic rate, chlorophyll content, salt tolerance, freezing and cold stress tolerance, seedling establishment, drought response, osmotic stress tolerance, membrane stability, and abiotic stress response. Studies of related genes in other species link the family to drought tolerance, salt tolerance, ABA sensitivity, and traits such as seed size, germination rate, water use efficiency, and root architecture.
