LP1 — Pisum sativum

Summary

PSAT7G228160 (LP1) on garden pea chromosome 7 encodes a non-specific lipid-transfer protein (nsLTP) belonging to the bifunctional inhibitor/LTP/seed storage family. The protein exhibits lipid carrier activity, lipid binding, calmodulin binding, calcium ion binding, and protein binding. LP1 is associated with phospholipid transfer to membranes, cutin anabolism, 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, cell wall, plasmodesmata, secretory vesicles, and plastids. The gene has been connected to flowering time, seed growth and development, leaf senescence, ethylene sensitivity, jasmonic acid content, stomatal closure, and abscisic acid sensitivity. Related genes in other species link the family to yield and nitrogen use efficiency.
