LP2 — Daucus carota subsp. sativus

Summary

DCAR_015339 (LP2, DcLP2) on carrot chromosome 4 encodes a protein belonging to the plant nsLTP domain and the bifunctional inhibitor/LTP/seed storage superfamily. The product exhibits lipid carrier, nutrient reservoir, and lipid-binding activities. It is associated with phospholipid transfer to membranes, cutin anabolism and cuticle development, lipid transport, seed development, somatic embryogenesis, programmed cell death, and response to thirst. The protein localises to the plant-type cell wall, plasmodesmata, plasma membrane, endosome, Golgi, and extracellular space. LP2 is linked to photosynthetic rate, drought tolerance, hypocotyl elongation, shoot development and branching, cuticle permeability, gravitropism, cold tolerance, flowering time, pollen tube growth, seed set, and root development. Studies of related genes in other species connect the family to pathogen resistance, cuticle-cell wall integrity, yield, nitrogen use efficiency, and salt stress tolerance.
