LP1 — Hordeum vulgare subsp. vulgare

Summary

HORVU.MOREX.R3.2HG0198700 (symbol LP1, also known as HvLP1) on barley chromosome 2H encodes a protein with a Plant_nsLTP domain and a bifunctional inhibitor/lipid-transfer/seed storage domain. The product exhibits lipid carrier, chitin-binding, chitosan-binding, calmodulin-binding, calcium ion-binding, protein kinase, and transmembrane receptor protein kinase activities. This gene is associated with phospholipid transfer to membranes, lipid transport, cutin-based cuticle development, plant epidermal cell differentiation, somatic embryogenesis, and cellular responses to chitin and bacterial molecules. It has been linked to traits including abscisic acid and jasmonic acid content, soluble protein content, bacterial blight disease resistance, leaf senescence, seed growth and development, flowering time, and salt tolerance. Studies of related genes in other species connect the family to cuticle integrity, pathogen resistance, freezing tolerance, seed set, and yield.
