LSP — Hordeum vulgare subsp. vulgare

Summary

HORVU.MOREX.R3.3HG0327270 (HvLSP) encodes a eukaryotic translation initiation factor 4E (eIF4E) family protein with RNA m7G cap binding, translation initiation factor activity, and linoleate 13S-lipoxygenase activity. The gene is associated with responses to viruses, bacteria, fungi, herbivores, and insects, as well as regulation of defense responses, jasmonic acid and salicylic acid signaling, photoperiodic flowering, and lipid oxidation. It has been linked to barley yellow mosaic virus and barley mild mosaic virus resistance, aphid response, grain yield, straw yield, root hair length, root thickness, stem senescence, leaf senescence, UV-B light sensitivity, and stomatal closure. The protein localizes to the cytosol, plastid, chloroplast thylakoid membrane, stress granules, and P-bodies. Related genes in other species are linked to potyvirus resistance, salt tolerance, and cold acclimation.
