LP2 — Capsicum annuum

Summary

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