LP1 — Triticum turgidum subsp. durum

Summary

TRITD2AV1G263760, designated LP1 on durum wheat chromosome 2A, encodes a protein belonging to the plant nsLTP domain and the bifunctional inhibitor/LTP/seed storage superfamily. The product exhibits lipid carrier, chitin-binding, and calcium ion-binding activities, and is associated with lipid transport, cutin-based cuticle development, phospholipid transfer to membranes, and cellular responses to chitin and bacterial molecules. LP1 has been linked to bacterial blight disease resistance, drought tolerance, salt tolerance, leaf senescence, seed development, flowering time, abscisic acid sensitivity, and jasmonic acid content. The protein localises to the apoplast, plant-type cell wall, plasmodesmata, secretory vesicles, and endomembrane compartments. Studies of related LTP family members in other species connect the family to cuticle integrity, pathogen resistance, seed germination, and stress tolerance.
