LTP — Cicer arietinum

Summary

LP1 (LTP) on chickpea chromosome 6 encodes a bifunctional inhibitor/plant lipid transfer protein/seed storage helical domain-containing protein with lipid carrier, lipid binding, calmodulin binding, calcium ion binding, protein binding, nutrient reservoir and IgE binding activities. The gene is associated with phospholipid transfer to membranes, lipid transport, cutin anabolism, cuticle development, calcium ion detection, mechanical stimulus response, epidermal cell differentiation, programmed cell death, salinity response, abscisic acid response, defence responses to fungi and Gram-positive bacteria, secondary metabolism, and digestion. LP1 is linked to traits including jasmonic acid content, stomatal closure time, leaf senescence, seed development, abscisic acid sensitivity, flowering time, and salt tolerance. Phenotypic associations include seedling growth, hypocotyl length, cuticle permeability, gravitropism, pollen tube growth, seed set, salt and drought tolerance, cold and freezing tolerance, disease resistance and susceptibility, and shoot branching. The protein localises to secretory vesicles, chloroplast thylakoid, Golgi, endosome, apoplast, cell wall, plasmodesma and plastid.
