FFC — Pisum sativum

Summary

PSAT3G032320 (symbol FFC, preferred name PsFFC) in garden pea (Pisum sativum) on chromosome 3LG5 encodes a signal-recognition-particle GTPase. The gene is associated with SRP-dependent cotranslational membrane targeting, protein localization to chloroplasts, chloroplast thylakoid membrane protein import, photosynthetic electron transport in photosystem II, thylakoid membrane organization, response to high light intensity, protein folding, and brassinosteroid-mediated signaling. It localizes to the chloroplast thylakoid membrane, chloroplast envelope, and endoplasmic reticulum. Associations include chlorophyll ratio, starch content, nitrate uptake, chloroplast development, leaf composition, seedling growth, and traits such as extreme chlorosis with slower growth, yellow-green bushy plants, reduced chlorophyll levels, altered iron uptake, and increased salt stress sensitivity. Studies of related genes in other species link the family to thylakoid biogenesis, carotenoid content, and photosystem II antenna size.
