LP2 — Daucus carota subsp. sativus

Summary

DCAR_009007 (LP2, DcLP2) on carrot chromosome 3 encodes a non-specific lipid-transfer protein (nsLTP) with lipid carrier and lipid-binding activity. This gene is associated with phospholipid transfer to membranes, cutin-based cuticle development, plant epidermal cell differentiation, somatic embryogenesis, programmed cell death, and response to thirst. The encoded protein localises to the plant-type cell wall, plasmodesmata, plasma membrane, Golgi, endosome, trans-Golgi network, and extracellular space. LP2 is linked to photosynthetic rate, drought tolerance, hypocotyl elongation, shoot development and branching, gravitropism, cuticle permeability and integrity, flower development, pollen tube growth, seed set, and longitudinal cell elongation. Studies of related genes in other species connect the family to pathogen resistance, cuticle-cell wall interface integrity, yield, nitrogen use efficiency, and salt stress tolerance.
