LEA — Triticum turgidum subsp. durum

Summary

TRITD0UV1G130240, designated TtLEA and also known by synonyms such as DHN1 and RAB16A, encodes a dehydrin-family protein on the unplaced chromosome of durum wheat (Triticum turgidum subsp. durum). 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 thirst response. It localizes to the vesicle membrane, cytosol, and nucleus. The gene has been linked to salinity tolerance, germination rate, photosynthetic rate, seedling establishment, drought, desiccation tolerance, and salt stress tolerance. Related genes in other species connect the family to winter survival, water stress response, abscisic acid content, cold tolerance, and drought tolerance.
