PPI2 — Pisum sativum

Summary

PSAT5G306400 (symbol PPI2, also known as PsTOC159) on garden pea chromosome 5LG3 encodes a protein with chloroplast-targeting sequence receptor activity and protein translocase activity, and contains TOC159_MAD, Apaf_helical and P-loop_NTPase domains. It is associated with the Toc and Tic complexes, chloroplast membranes and thylakoids, and linked to protein-chloroplast targeting, chloroplast stroma protein import, and regulation of photosynthesis and stomatal opening. The gene is associated with photosynthetic rate, water use efficiency, biomass yield, seed yield, seed viability, leaf color, flowering time, reproductive growth time, and responses to cold, carbon dioxide, osmotic stress and low temperature. Related genes in other species are linked to plastid protein import, chloroplast development, photosystem II quantum yield, seed development, ABA responsiveness in stomata, and plant viability.
