LP2 — Asparagus officinalis

Summary

AoLP2 (LP2) on asparagus chromosome 2 encodes a bifunctional inhibitor/plant lipid transfer protein/seed storage helical domain-containing protein with lipid carrier and lipid binding activities. It is associated with phospholipid transfer to membranes, lipid transport, cutin-based cuticle development, plant epidermal cell differentiation, programmed cell death, and response to thirst. The protein localises to the plant-type cell wall, plasmodesma, plasma membrane, Golgi, endosome, TGN, cytosol, and extracellular space. LP2 has been connected to photosynthetic rate, drought tolerance and response, cuticle permeability and integrity, gravitropism, hypocotyl elongation, flower development, pollen tube growth, seed set, shoot development and branching, sexual reproduction, and cold and osmotic stress tolerance. Studies of related genes in other species link the family to yield, nitrogen use efficiency, pathogen resistance, salt stress tolerance, and clubroot disease resistance.
