LP1 — Pisum sativum

Summary

PsLP1 (LP1) on chromosome 7LG7 encodes a non-specific lipid-transfer protein (nsLTP) with lipid carrier and lipid binding activities, and also binds calmodulin and calcium ions. The gene is associated with phospholipid transfer to membranes, cutin anabolism and cuticle development, lipid transport, plant epidermal cell differentiation, programmed cell death, defence responses to bacteria and fungi, and responses to abscisic acid and salinity. Associations with traits include ethylene sensitivity, jasmonic acid content, stomatal closure, leaf senescence, seed growth and development, flowering time, and abscisic acid sensitivity. Phenotypic links include seedling growth, salt and drought tolerance, cold and freezing tolerance, disease resistance and susceptibility, cuticle permeability, pollen tube growth, seed set, root development, and flower development. The protein localises to the apoplast, cell wall, plasmodesmata, secretory vesicles, Golgi, plastids, and endosomes.
