LEA — Hordeum vulgare subsp. vulgare

Summary

HORVU.MOREX.R3.5HG0507410, also known as Dhn1 or LEA, encodes a dehydrin family protein on barley chromosome 5H. The product exhibits lipid, phosphatidylglycerol, phosphatidylserine, phosphatidate and phosphoinositide binding activities. This gene is associated with responses to water, cold, heat, abscisic acid and thirst, as well as cold acclimation, embryogenesis, seed development and germination, chlorophyll fluorescence, glucose effect, lipid transport and homeostasis. It localises to the vesicle membrane, cytosol and nucleus. Associations include winter survival, cold and heat tolerance, water use efficiency, photosynthetic rate, quantum yield, chlorophyll content, leaf size, sugar and protein content, abscisic acid content, germination rate, seedling establishment, drought, salinity, salt stress tolerance and desiccation tolerance. Studies of related genes in other species link the family to drought tolerance, salt tolerance and abiotic stress responses.
