LEA — Hordeum vulgare subsp. vulgare

Summary

HORVU.MOREX.R3.6HG0622770, designated HvLEA, encodes a protein with a dehydrin conserved domain. The product exhibits lipid binding activity, specifically binding phosphatidylglycerol, phosphatidylserine, phosphatidate, and phosphoinositides. HvLEA is associated with responses to water, cold, heat, and abscisic acid, as well as cold acclimation, embryogenesis, seed development and germination, and the glucose effect. It is linked to chlorophyll fluorescence, lipid transport, and homeostasis. The protein localises to the vesicle membrane, cytosol, and nucleus. HvLEA has been connected to traits including water use efficiency, photosynthetic rate, quantum yield, leaf size, sugar content, abscisic acid content, heat and cold tolerance, and germination rate. Phenotypic associations include drought, salinity, desiccation tolerance, salt stress tolerance, seedling establishment, and ABA response. Studies of related genes in other species link the family to winter survival, grain yield, salinity tolerance, and seed maturation.
