LP1 — Pisum sativum

Summary

PsLP1 (LP1) on chromosome 7LG7 encodes a protein with a Plant_nsLTP domain and bifunctional inhibitor/lipid-transfer/seed storage domains, and has lipid carrier activity and lipid binding, calmodulin binding, calcium ion binding, and protein binding activities. It is associated with phospholipid transfer to membranes, digestion, cutin anabolism, calcium ion detection, cutin-based cuticle development, mechanical stimulus response, lipid transport, killing of cells of other organisms, secondary metabolism, plant epidermal cell differentiation, programmed cell death, salinity response, response to thirst, defence responses to bacteria and fungi, and response to abscisic acid. The gene is linked to ethylene sensitivity, jasmonic acid content, stomatal complex closure time, leaf senescence, seed growth and development, abscisic acid sensitivity, flowering time, and salt tolerance. Related genes in other species link the family to cuticle integrity, drought tolerance, freezing tolerance, yield, nitrogen use efficiency, and resistance to bacterial infection and clubroot disease.
