LP2 — Capsicum annuum

Summary

CaLP2 (LP2, T459_05090) on pepper chromosome 2 encodes a non-specific lipid-transfer protein 1 belonging to the plant nsLTP family. The protein has lipid carrier and lipid binding activities and is associated with phospholipid transfer to membranes, lipid transport, cutin anabolism and cuticle development, anther and pollen development, fruit ripening, plant epidermal cell differentiation, programmed cell death, defence responses to fungi, and virus-induced post-transcriptional gene silencing. It localises to the plasma membrane, cell wall, Golgi, endosome, trans-Golgi network, plasmodesmata, cytosol and extracellular space. The gene is associated with photosynthetic rate, drought tolerance, cold tolerance, osmotic stress tolerance, flowering time, shoot and root development, hypocotyl elongation, gravitropism, cuticle permeability, pollen tube growth, seed set, and longitudinal cell elongation. Studies of related genes in other species connect the family to cuticle-cell wall integrity, pathogen resistance, salt stress tolerance, yield and nitrogen use efficiency.
