LSP — Hordeum vulgare subsp. vulgare

Summary

HORVU.MOREX.R3.3HG0225870, designated HvLSP, encodes a protein with translation initiation factor activity and RNA m7G cap binding, placing it in the eIF4E family. The gene is associated with responses to viruses, including barley yellow mosaic virus and barley mild mosaic virus resistance, as well as responses to bacteria, fungi, insects, and herbivores. It is linked to jasmonic acid and salicylic acid signaling, lipid oxidation, green leaf volatile biosynthesis, and photoperiodic flowering. Associations with grain yield, straw yield, stem senescence, root hair length, root thickness, and nitrogen use efficiency have been reported. The encoded protein localises to the cytosol, plastids, stress granules, and P bodies. Studies of related genes in other species link the family to potyvirus resistance, salt tolerance, and green leaf volatile production.
