LP1 — Triticum turgidum subsp. durum

Summary

TRITD2AV1G263770, also known as LP1 or TtLP1 on durum wheat chromosome 2A, encodes a protein belonging to the Plant_nsLTP family. The gene 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 growth and development, flowering time, and abscisic acid sensitivity. It localises to the apoplast, plant-type cell wall, plasmodesma, and secretory vesicles. Studies of related genes in other species connect the LTP family to cuticle integrity, pathogen resistance, seed set, and stress tolerance.
