LEA — Brachypodium distachyon

Summary

BRADI_4G22280V3, designated BdLEA (also known as BdDHN1, RAB16A, and other synonyms) on chromosome 4 of Brachypodium distachyon, encodes a dehydrin family protein characterized by a Dehydrin_CS domain. The product exhibits lipid binding, including phosphatidylglycerol, phosphatidylserine, phosphatidate, and phosphoinositide binding. BdLEA is associated with cold acclimation, embryogenesis, response to abscisic acid, and response to thirst. It localizes to the vesicle membrane, cytosol, and nucleus. The gene has been linked to photosynthetic rate, seedling establishment, drought, seed traits, salinity stress, and desiccation tolerance. Studies of related genes in other species connect the family to winter survival, water stress response, salt tolerance, cold tolerance, heat tolerance, seed maturation, and germination rate.
