LP1 — Triticum turgidum subsp. durum

Summary

TRITD0UV1G112900 (LP1) in durum wheat encodes a non-specific lipid-transfer protein family member with lipid carrier, lipid binding, and chitin binding activities, along with protein kinase and calmodulin binding functions. This gene is associated with lipid transport, phospholipid transfer to membranes, cutin-based cuticle development, and cellular responses to chitin and bacterial molecules. It is linked to plant epidermal cell differentiation, programmed cell death, and salt stress response. LP1 is associated with traits including bacterial blight disease resistance, drought tolerance, abscisic acid sensitivity, flowering time, leaf senescence, seed growth and development, and stomatal closure. The protein localizes to the apoplast, plant-type cell wall, secretory vesicles, plasmodesmata, and plastids. Studies of related genes in other species link the LTP family to yield, seed set, pollen fertility, and pathogen resistance.
