LP2 — Lactuca sativa

Summary

LsLP2 (LP2) on lettuce chromosome 1 encodes a non-specific lipid-transfer protein (nsLTP) belonging to the Plant_nsLTP family and possesses lipid carrier activity, lipid binding, and IgE binding molecular functions. The gene is associated with phospholipid transfer to membranes, cutin anabolism and cuticle development, lipid transport, plant epidermal cell differentiation, programmed cell death, defense response, and response to thirst. It localizes to the plant-type cell wall, plasmodesma, plasma membrane, endosome, Golgi, and cytosol. Associations include photosynthetic rate, drought tolerance, cold tolerance, osmotic stress tolerance, flowering time, shoot development and branching, hypocotyl elongation, pollen tube growth, seed set, and cuticle integrity. Studies of related genes in other species link the family to pathogen resistance, cuticle-cell wall interface integrity, yield, nitrogen use efficiency, and salt stress tolerance.
