LEA — Hordeum vulgare subsp. vulgare

Summary

HORVU.MOREX.R3.5HG0424060, designated HvLEA, encodes a protein containing an LEA_SMP domain. In barley, this gene is associated with response to water, cold, and heat, as well as with cold acclimation, seed development and germination, embryogenesis, lipid transport, chlorophyll fluorescence, and homeostasis. It is linked to traits including water use efficiency, photosynthetic rate, quantum yield, leaf size, sugar content, heat and cold tolerance, and germination rate. Studies of related genes in other species connect the family to drought and salinity tolerance, grain yield, grain weight and size, seed dormancy and maturation, sprouting tolerance, abscisic acid content, chlorophyll content, root length and branching, shoot dry weight, pollen fertility, and concentrations of zinc, iron, proline, and anthocyanins.
