LEA — Hordeum vulgare subsp. vulgare

Summary

HORVU.MOREX.R3.6HG0622760, also known as DHN4, LEA, or RAB21, encodes a dehydrin family protein on barley chromosome 6H. The product exhibits lipid, phosphatidylglycerol, phosphatidylserine, phosphatidate, and phosphoinositide binding activities. This gene is associated with responses to water, cold, heat, and abscisic acid, as well as cold acclimation, embryogenesis, seed development and germination, chlorophyll fluorescence, glucose effect, lipid transport, and homeostasis. It is linked to traits including cold and heat tolerance, water use efficiency, photosynthetic rate, quantum yield, leaf size, sugar content, abscisic acid content, and germination rate. The protein localises to the vesicle membrane, cytosol, and nucleus. Studies of related genes in other species connect the family to drought, salt, and desiccation tolerance, as well as grain yield, winter survival, and seed maturation.
