LEA — Triticum turgidum subsp. durum

Summary

TRITD5AV1G215030, designated TtLEA on durum wheat chromosome 5A, encodes a dehydrin 9 protein. The product exhibits lipid, phosphatidylglycerol, phosphatidylserine, phosphatidate, and phosphoinositide binding activities. TtLEA is associated with cold acclimation, salt response, seed development and germination, embryogenesis, response to abscisic acid, and response to thirst. It localises to the vesicle membrane, cytosol, and nucleus. The gene is linked to salinity tolerance, germination rate, photosynthetic rate, seedling establishment, drought, desiccation tolerance, and salt stress tolerance. Studies of related genes in other species connect the family to winter survival, water stress response, abscisic acid content and sensitivity, cold and heat tolerance, root and leaf traits, seed maturation and size, and cell membrane stability.
