FRD4 — Pisum sativum
Summary
PsFRD4 (PSAT4G153600) on garden pea chromosome 4LG4 encodes a protein with SRP54-type domains, GTPase activity, and protein translocase activity. The gene is associated with SRP-dependent cotranslational membrane targeting, chloroplast thylakoid membrane protein import, photosynthetic electron transport in photosystem II, and thylakoid membrane organization. It localizes to the chloroplast thylakoid, stroma, and SRP complex. PsFRD4 has been connected to leaf color, leaf chlorophyll content, chloroplast development, root morphology, and iron uptake. It is linked to increased salt stress sensitivity, chlorophyll content, light-harvesting complex composition, photosystem I/II ratio, and thylakoid protein biogenesis. Studies of related genes in other species link the family to thylakoid biogenesis, carotenoid accumulation, and severe chlorosis with reduced growth.
