LP1 — Pisum sativum

Summary

PsLP1 (PSAT7G234440) on garden pea chromosome 7LG7 encodes a non-specific lipid-transfer protein (nsLTP) family member with lipid carrier activity, lipid binding, calmodulin binding, calcium ion binding, and protein binding functions. The gene is associated with phospholipid transfer to membranes, cutin-based cuticle development, lipid transport, plant epidermal cell differentiation, programmed cell death, defence responses to bacteria and fungi, salinity response, and response to abscisic acid. It localises to the apoplast, plant-type cell wall, plasmodesma, secretory vesicle, and chloroplast thylakoid. PsLP1 has been linked to flowering time, seed growth and development, leaf senescence, ethylene sensitivity, jasmonic acid content, stomatal closure, salt tolerance, drought tolerance, cold tolerance, disease resistance, cuticle permeability, and suberin formation. Related genes in other species connect the family to cuticle integrity, yield, nitrogen use efficiency, salt stress tolerance, and pathogen resistance.
