LEA — Triticum turgidum subsp. durum

Summary

TRITD5AV1G197500, designated TtLEA on durum wheat chromosome 5A, encodes a dehydrin family protein containing the Dehydrin_CS domain. The product binds phosphatidylglycerol, phosphatidylserine, phosphatidate, phosphoinositides and other lipids. TtLEA is associated with cellular responses to desiccation, salt, drought, mannitol, light stimulus and wounding, as well as cold acclimation, abscisic acid response, embryogenesis, seed development and germination. It localises to the vesicle membrane, cytosol, cytoplasm and nucleus. The gene is linked to salinity tolerance, germination rate, photosynthetic rate, seedling establishment, drought, salt stress tolerance, desiccation tolerance, ABA, seed, and salinity. Studies of related genes in other species connect the family to winter survival, water stress response, abscisic acid content, cell membrane stability, cold and heat tolerance, and seed maturation traits.
