LSP — Hordeum vulgare subsp. vulgare

Summary

HORVU.MOREX.R3.1HG0041260 (HvLSP) on barley chromosome 1H encodes a protein with translation initiation factor activity and RNA m7G cap binding, placing it in the eIF4E family. It is associated with linoleate 13S-lipoxygenase activity, salicylic acid binding, and localises to the cytosol, plastid, stress granules and P-bodies. The gene is linked to responses to viruses, fungi, bacteria, insects, herbivores, wounding, jasmonic acid, and photoperiodic flowering, as well as to lipid oxidation, green leaf volatile biosynthesis, and jasmonic acid anabolism. Associations with barley yellow mosaic virus resistance, barley mild mosaic virus resistance, insect resistance, grain yield, straw yield, stem senescence, root hair length, and salt tolerance have been reported. Studies of related genes in other species connect the family to jasmonate biosynthesis, green leaf volatile production, and defense against herbivores and fungal pathogens.
