LP1 — Hordeum vulgare subsp. vulgare

Summary

HORVU.MOREX.R3.3HG0227370 (LP1, HvLP1) on barley chromosome 3H encodes a protein with plant nsLTP, bifunctional inhibitor/LTP/seed storage, and bifunctional inhibitor/LTP/seed superfamily domains. The product exhibits lipid carrier, lipid binding, chitin binding, chitosan binding, calcium ion binding, calmodulin binding, protein kinase, and transmembrane receptor protein kinase activities. LP1 is associated with phospholipid transfer to membranes, lipid transport, cutin-based cuticle development, plant epidermal cell differentiation, somatic embryogenesis, detection of peptidoglycan and fungal molecules, cellular responses to chitin and bacterial molecules, and positive regulation of the hypersensitive response. The gene has been linked to abscisic acid and jasmonic acid content, bacterial blight disease resistance, leaf senescence, seed growth and development, flowering time, salt tolerance, and soluble protein content. Related genes in other species connect the family to flowering time, osmotic stress tolerance, and root development.
