LP2 — Asparagus officinalis

Summary

AoLP2 (LP2) on asparagus chromosome 2 encodes a non-specific lipid transfer protein (nsLTP) belonging to the Plant_nsLTP and bifunctional inhibitor/LTP/seed storage superfamilies. The product exhibits lipid carrier activity, lipid binding, and IgE binding. It is associated with phospholipid transfer to membranes, lipid transport, cutin anabolism and cuticle development, plant epidermal cell differentiation, programmed cell death, seed trichome elongation, and response to thirst. The protein localises to the extracellular region, plasmalemma, plant-type cell wall, plasmodesma, Golgi, TGN, endosome, and cytosol. The gene has been connected to photosynthetic rate, drought tolerance, cuticle permeability, gravitropism, hypocotyl elongation, shoot development and branching, flower development, pollen tube growth, seed set, and cold and osmotic stress tolerance. Studies of related genes in other species link the LTP family to pathogen resistance, salt stress tolerance, yield, and nitrogen use efficiency.
