LP2 — Daucus carota subsp. sativus

Summary

DCAR_020877 (DcLP2) on carrot chromosome 6 encodes a non-specific lipid-transfer protein (nsLTP) belonging to the bifunctional inhibitor/LTP/seed storage superfamily, with lipid carrier and lipid-binding molecular functions. The gene is associated with phospholipid transfer to membranes, lipid transport, cutin-based cuticle development, plant epidermal cell differentiation, somatic embryogenesis, programmed cell death, defence response to fungi, and response to thirst. It has been linked to photosynthetic rate, drought tolerance, hypocotyl elongation, shoot development, shoot branching, sexual reproduction, drought response, cuticle permeability, gravitropism, hypocotyl length, shoot growth, flower development, longitudinal cell elongation, pollen tube growth, seed set, cuticle integrity, and lipid transfer. The protein localises to the cell wall, plasma membrane, plasmodesmata, Golgi, endosome, trans-Golgi network, and extracellular region. Studies of related genes in other species link the family to cuticle-cell wall interface integrity, pathogen resistance, and salt stress tolerance.
