LEA — Triticum turgidum subsp. durum

Summary

TRITD6AV1G013380, also known as TtLEA, encodes a dehydrin family protein on durum wheat chromosome 6A. The product binds phosphatidylglycerol, phosphatidylserine, phosphatidate, phosphoinositides and other lipids. In durum wheat, this gene is associated with cold acclimation, salt response, abscisic acid response, seed development and germination, embryogenesis, and response to thirst. It is linked to vesicle membrane, cytosol and nuclear localisation. Associations with salinity tolerance, germination rate, photosynthetic rate, seedling establishment, drought, seed traits, desiccation tolerance and salt stress tolerance have been recorded. Studies of related genes in other species link the family to winter survival, water stress response, abscisic acid content and sensitivity, cold and heat tolerance, cell membrane stability, water use efficiency, seed maturation and size, root traits, and spikelet sterility.
