LP2 — Lactuca sativa

Summary

LsLP2 (LP2) on chromosome 1 of garden lettuce encodes a non-specific lipid-transfer protein belonging to the Plant_nsLTP family. The gene product exhibits lipid carrier and lipid binding activities, and is associated with phospholipid transfer to membranes, cutin anabolism and cuticle development, lipid transport, plant epidermal cell differentiation, programmed cell death, and defence response to fungi. It localises to the plant-type cell wall, plasmodesma, extracellular region, and endomembrane compartments. Associations with agronomically relevant traits include photosynthetic rate, drought tolerance, cold tolerance, osmotic stress tolerance, seed set, shoot development and branching, flowering time, root development, and cuticle integrity. Studies of related genes in other species link the family to yield, nitrogen use efficiency, pathogen resistance, and salt stress tolerance.
