LP1 — Pisum sativum

Summary

PSAT7G234520 (LP1, also known as PsCDF3 and PsATLTP1) encodes a non-specific lipid-transfer protein (nsLTP) family member on garden pea chromosome 7LG7. The product possesses lipid carrier and calcium/calmodulin-binding activities. LP1 is associated with phospholipid transfer to membranes, cutin-based cuticle development, plant epidermal cell differentiation, programmed cell death, and responses to abscisic acid, salinity, and bacterial and fungal pathogens. The gene has been linked to ethylene and abscisic acid sensitivity, flowering time, leaf senescence, seed growth and development, stomatal closure, and jasmonic acid content. Associations with salt tolerance, drought response, cold tolerance, disease resistance, cuticle permeability, hypocotyl elongation, shoot development, and seed set have also been observed. Studies of related genes in other species connect the family to yield, nitrogen use efficiency, embryo development, and resistance to bacterial infection and clubroot disease.
