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 the bifunctional inhibitor/LTP/seed storage superfamily. The protein exhibits lipid carrier activity, lipid binding, and IgE binding, and is associated with phospholipid transfer to membranes, lipid transport, cutin anabolism and cuticle development, plant epidermal cell differentiation, programmed cell death, defense response, and response to thirst. It localizes to the plant-type cell wall, plasmodesma, plasma membrane, Golgi, endosome, TGN, cytosol, and extracellular space. The gene is associated with photosynthetic rate, drought tolerance, cold tolerance, osmotic stress tolerance, flowering time, shoot development and branching, hypocotyl elongation, gravitropism, cuticle permeability, pollen tube growth, seed set, and root development. Studies of related genes in other species connect the family to pathogen resistance, salt stress tolerance, yield, nitrogen use efficiency, and clubroot disease resistance.
