LEA — Hordeum vulgare subsp. vulgare

Summary

HORVU.MOREX.R3.3HG0305460, designated HvLEA, encodes a dehydrin family protein on barley chromosome 3H. The gene is associated with responses to water, cold, heat, and abscisic acid, as well as with cold acclimation, seed development and germination, embryogenesis, lipid transport, chlorophyll fluorescence, glucose effect, and homeostasis. It is linked to the cytosol and nucleus. Associations include abscisic acid content, water use efficiency, heat and cold tolerance, photosynthetic rate, quantum yield, sugar content, leaf size, and germination rate. The gene has been connected to drought, salinity stress, desiccation tolerance, seedling establishment, and ABA responses. Studies of related genes in other species link the family to drought tolerance, salt tolerance, grain yield, winter survival, and seed maturation.
