LEA — Triticum turgidum subsp. durum

Summary

TRITD5BV1G211650, designated TtLEA on durum wheat chromosome 5B, encodes a dehydrin-family protein with lipid-binding properties, including phosphatidylglycerol, phosphatidylserine, phosphatidate and phosphoinositide binding. The gene is associated with cold acclimation, salt response, seed development and germination, embryogenesis, response to abscisic acid, and response to thirst. It has been linked to salinity tolerance, germination rate, photosynthetic rate, seedling establishment, drought, desiccation tolerance, and salt stress tolerance. The protein localises to the vesicle membrane, cytosol and nucleus. Studies of related genes in other species connect the family to winter survival, water stress response, cold and heat tolerance, abscisic acid sensitivity, seed maturation, root traits, and cell membrane stability.
