LP1 — Pisum sativum

Summary

PsLP1 (PSAT7G234720, LP1) on chromosome 7LG7 encodes a non-specific lipid-transfer protein (nsLTP) with lipid carrier and lipid binding activities, as well as calmodulin and calcium ion binding. It is associated with phospholipid transfer to membranes, lipid transport, cutin-based cuticle development, plant epidermal cell differentiation, programmed cell death, and responses to abscisic acid, salinity, and bacterial and fungal defence. The gene is linked to traits including flowering time, seed growth and development, leaf senescence, ethylene and abscisic acid sensitivity, stomatal closure, and jasmonic acid content. Phenotypic associations include salt and drought tolerance, cold and freezing tolerance, disease resistance and susceptibility, seedling growth, root development, and cuticle integrity. The protein localises to the apoplast, cell wall, plasmodesmata, secretory vesicles, and plastids.
