LEA — Solanum tuberosum

Summary

PGSC0003DMG400003530, the potato gene TAS14 (also known as StRAB18, StLEA, LTI30, and XERO2) on chromosome 2, encodes a dehydrin family protein with a dehydrin conserved domain and exhibits phosphatidylglycerol, phosphatidylserine, phosphatidate, phosphoinositide, and general lipid binding activities. In potato, TAS14 is associated with drought stress response, cellular responses to desiccation, salt, light, and the hormone 1-aminocyclopropane-1-carboxylic acid, as well as cold acclimation, immune memory response, wounding, embryogenesis, seed development and germination, cell wall modification, and carbohydrate metabolism. The protein localizes to the vesicle membrane, membrane, cytosol, cytoplasm, and nucleus. It is also linked to photosynthetic rate, freezing and cold stress tolerance, seedling establishment, membrane stability, and responses to abscisic acid, osmotic stress, and dehydration. Studies of related genes in other species connect the family to drought tolerance, salt tolerance, ABA signaling, and low temperature response.
