LEA — Lactuca sativa

Summary

LsLEA (LSAT_V11C500272000) on lettuce chromosome 5 encodes a dehydrin family protein with a Dehydrin_CS domain and is associated with phosphatidylglycerol, phosphatidylserine, phosphatidate, phosphoinositide, and lipid binding activities, along with metal binding. The gene is associated with responses to abscisic acid, cold, drought, salt, mannitol, 1-aminocyclopropane-1-carboxylic acid, and light stimulus, as well as cold acclimation, embryogenesis, ABA signaling, defence against fungi, and thirst response. It is linked to transpiration rate, photosynthetic rate, chlorophyll content, and salt tolerance traits, and to phenotypes including freezing and cold stress tolerance, seedling establishment, drought and osmotic stress response, membrane stability, and abiotic stress response. The protein localises to the vesicle membrane, membrane, cytosol, cytoplasm, and nucleus. Studies of related genes in other species connect the family to drought tolerance, ABA sensitivity, and low-temperature response.
