EP2 — Daucus carota subsp. sativus

Summary

DCAR_015338 (EP2) on carrot chromosome 4 encodes a non-specific lipid-transfer protein (nsLTP) belonging to the Plant_nsLTP family, with lipid carrier activity and lipid binding functions. The gene is associated with phospholipid transfer to membranes, cutin-based cuticle development, somatic embryogenesis, defence responses to fungi, programmed cell death, and sensitization. It localises to the plant-type cell wall, plasmodesma, plasma membrane, endosome, Golgi, and cytosol. EP2 is associated with drought tolerance, cuticle permeability, photosynthetic rate, hypocotyl elongation, shoot development and branching, flower development, pollen tube growth, seed set, gravitropism, and cold tolerance. 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.
