LP1 — Pisum sativum

Summary

PSAT7G228120 (LP1, also known as PsLTP1) encodes a protein belonging to the plant nsLTP family, with lipid carrier and lipid binding activities, as well as calmodulin and calcium ion binding. The gene is associated with phospholipid transfer to membranes, lipid transport, cutin-based cuticle development, plant epidermal cell differentiation, programmed cell death, defence response to fungi, salinity response, and response to abscisic acid. It has been linked to traits including flowering time, seed growth and development, leaf senescence, ethylene sensitivity, jasmonic acid content, stomatal closure, and abscisic acid sensitivity. Phenotypic associations include salt and drought tolerance, freezing tolerance, disease resistance and susceptibility, seedling growth, hypocotyl elongation, pollen tube growth, seed set, and shoot development. The protein localises to the apoplast, plant-type cell wall, plasmodesma, secretory vesicle, and chloroplast thylakoid. Studies of related genes in other species link the family to yield, nitrogen use efficiency, pathogen resistance, and embryo development.
