LP1 — Hordeum vulgare subsp. vulgare

Summary

HORVU.MOREX.R3.2HG0198710 (HvLP1) on barley chromosome 2H encodes a non-specific lipid-transfer protein (nsLTP) with lipid carrier, chitin-binding and chitosan-binding activities, as well as protein kinase and calmodulin-binding functions. The gene is associated with lipid transport, cuticle and cutin development, phospholipid transfer to membranes, plant epidermal cell differentiation, somatic embryogenesis, and responses to chitin, mechanical stimuli, and bacterial and fungal molecules. It localises to the apoplast, cell wall, plasmodesmata, secretory vesicles, Golgi, endosomes and plastids. HvLP1 is linked to traits including abscisic acid and jasmonic acid content, bacterial blight disease resistance, leaf senescence, seed growth, flowering time, protein content, salt tolerance, and stomatal closure. Studies of related genes in other species connect the family to drought recovery, cold tolerance, yield, seed set, pathogen resistance, and nitrogen use efficiency.
