LEA — Hordeum vulgare subsp. vulgare

Summary

HORVU.MOREX.R3.5HG0516830 (HvLEA, also known as Dhn9) on barley chromosome 5H encodes a dehydrin protein belonging to the Dehydrin_CS family and is annotated with 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 abscisic acid content, quantum yield, sugar content, leaf size, water use efficiency, heat and cold tolerance, germination rate, photosynthetic rate, seedling establishment, drought, salinity, desiccation tolerance and salt stress tolerance. Studies of related genes in other species link the family to drought tolerance, salt tolerance, grain yield, seed size and winter survival.
