LEA — Hordeum vulgare subsp. vulgare

Summary

HORVU.MOREX.R3.5HG0424150, designated HvLEA, encodes a late embryogenesis abundant (LEA) protein. In barley, this gene is associated with responses to water, cold, and heat, as well as cold acclimation, seed development and germination, embryogenesis, lipid transport, chlorophyll fluorescence, and homeostasis. It has been linked to traits including water use efficiency, photosynthetic rate, quantum yield, leaf size, sugar content, germination rate, and heat and cold tolerance. Studies of related LEA family members in other species connect the family to drought and salinity tolerance, grain yield, grain size and weight, seed dormancy and maturation, sprouting tolerance, abscisic acid content, root and shoot growth, chlorophyll content, and mineral concentrations.
