LEA — Hordeum vulgare subsp. vulgare

Summary

HORVU.MOREX.R3.6HG0622790, also known as Dhn7 or LEA, encodes a dehydrin protein on barley chromosome 6H. The product belongs to the dehydrin family and 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, seed development and germination, embryogenesis, chlorophyll fluorescence, glucose effect, lipid transport, and homeostasis. It localizes to the vesicle membrane, cytosol, and nucleus. Associations include traits such as cold and heat tolerance, water use efficiency, photosynthetic rate, quantum yield, leaf size, sugar and abscisic acid content, and germination rate. Phenotypic links include drought, salinity, desiccation tolerance, seedling establishment, and ABA response. Studies of related genes in other species connect the family to drought tolerance, salt tolerance, grain yield, winter survival, and seed maturation.
