LP1 — Hordeum vulgare subsp. vulgare

Summary

HORVU.MOREX.R3.3HG0227320 (HvLP1) on barley chromosome 3H encodes a protein with a Plant_nsLTP domain and annotated lipid carrier activity, chitosan and chitin binding, and additional functions including protein kinase and calmodulin-binding activities. The gene is associated with lipid transport, cutin-based cuticle development, phospholipid transfer to membranes, and plant epidermal cell differentiation. It 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 stomatal closure. Localisation evidence connects the product to the apoplast, plant-type cell wall, plasmodesmata, and secretory vesicles. Studies of related genes in other species associate the family with cuticle integrity, pathogen resistance, freezing tolerance, seed set, and yield traits.
