LP2 — Capsicum annuum

Summary

CaLP2 (LP2) on pepper chromosome 9 encodes a plant non-specific lipid-transfer protein (nsLTP) with lipid carrier and lipid-binding activity. The gene is associated with phospholipid transfer to membranes, cutin anabolism and cuticle development, lipid transport, anther and pollen development, pollen germination, fruit ripening, programmed cell death, defense responses, and virus-induced PTGS. It is linked to drought tolerance, cold tolerance, osmotic stress tolerance, photosynthetic rate, cuticle permeability and integrity, hypocotyl elongation, shoot development and branching, flowering time, flower development, root development, gravitropism, seed set, and pollen tube growth. The protein localizes to the plasma membrane, cell wall, plasmodesmata, Golgi, endosome, TGN, cytosol, and extracellular space. Studies of related genes in other species connect the family to pathogen resistance, salt stress tolerance, yield, nitrogen use efficiency, and clubroot disease resistance.
