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 and lipid binding activities, and is associated with phospholipid transfer to membranes, lipid transport, cutin-based 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, and trans-Golgi network. The gene is linked to photosynthetic rate, drought tolerance, cuticle permeability, gravitropism, hypocotyl elongation, shoot development and branching, flower development, pollen tube growth, seed set, and longitudinal cell elongation. Studies of related genes in other species connect the family to cuticle-cell wall interface integrity, pathogen resistance, salt stress tolerance, yield, nitrogen use efficiency, and flowering time.
