LP1 — Triticum turgidum subsp. durum

Summary

TRITD3BV1G016440, also known as LP1 or TtLP1 on durum wheat chromosome 3B, encodes a non-specific lipid-transfer protein family member with lipid carrier, lipid binding, chitin and chitosan binding activities, as well as protein kinase and calmodulin-binding functions. The gene is associated with phospholipid transfer to membranes, cutin-based cuticle development, lipid transport, and cellular responses to chitin and bacterial molecules. It has been linked to traits including bacterial blight disease resistance, drought tolerance, salt tolerance, flowering time, leaf senescence, seed growth and development, abscisic acid sensitivity, and stomatal closure. Localisation evidence connects the product to the apoplast, plant-type cell wall, secretory vesicles, plasmodesmata, and Golgi. Related genes in other species link the family to cuticle integrity, pathogen resistance, seed set, and abiotic stress tolerance.
