LTP2 — Cicer arietinum

Summary

PvLTP2 (LTP2) on chickpea chromosome MU967759.1 encodes a non-specific lipid-transfer protein (nsLTP2) with lipid binding, lipid carrier, calmodulin binding, calcium ion binding, protein binding, nutrient reservoir and IgE binding activities. The gene is associated with lipid transport, phospholipid transfer to membranes, cutin anabolism, cutin-based cuticle development, calcium ion detection, mechanical stimulus response, epidermal cell differentiation, programmed cell death, salinity response, response to abscisic acid, defence response to fungi, secondary metabolism, and over 45 additional biological processes. It has been connected to traits including jasmonic acid content, stomatal complex closure time, low temperature stress response, leaf senescence trait, seed growth and development trait, flowering time trait, and abscisic acid sensitivity. Phenotypic associations include seedling growth, hypocotyl length, cuticle permeability, gravitropism, drought response, cuticle integrity, and phenotypic variation. The protein localises to secretory vesicles, chloroplast thylakoid, plant-type cell wall, apoplast, plasmodesma, Golgi complex, plastid, and other compartments. Studies of related genes in other species link it to cuticle-cell wall interface integrity, resistance to bacterial infection, salt stress tolerance, clubroot disease resistance, and thigmomorphogenesis.
