LP2 — Asparagus officinalis

Summary

AoLP2 (LP2) on asparagus chromosome 2 encodes a non-specific lipid-transfer protein (nsLTP) belonging to the bifunctional inhibitor/LTP/seed storage superfamily. The product exhibits lipid carrier activity, lipid binding, and IgE binding, and is associated with phospholipid transfer to membranes, lipid transport, cutin anabolism, cuticle development, plant epidermal cell differentiation, programmed cell death, and response to thirst. It localises to the plant-type cell wall, plasmodesma, plasma membrane, Golgi, endosome, TGN, cytosol, and extracellular space. The gene is linked to photosynthetic rate, drought tolerance, hypocotyl elongation, shoot development, shoot branching, sexual reproduction, drought response, cuticle permeability, gravitropism, hypocotyl length, shoot growth, cold tolerance, flowering time, osmotic stress tolerance, flower development, longitudinal cell elongation, pollen tube growth, seed set, root development, lipid transfer, and cuticle integrity. Studies of related genes in other species connect the family to pathogen resistance, salt stress tolerance, yield, nitrogen use efficiency, and clubroot disease resistance.
