MAR1 — Pisum sativum

Summary

PsMAR1 (PSAT7G209800) on chromosome 7LG7 encodes a protein with domains including IAP75, POTRA2_Toc75, and BamA-like, and exhibits protein translocase activity, GTP binding, and chloroplast targeting sequence receptor activity. The gene is associated with chloroplast organization, protein import into the chloroplast stroma, etioplast organization, regulation of photosynthesis, and cellular response to cold. It localizes to the Toc complex, chloroplast outer membrane, and chloroplast envelope. Associations include chlorophyll content, linolenic and oleic acid content, plastid and chloroplast development, flowering time, root thickness, disease tolerance, and pollen fertility restoration. Related genes in other species link the family to etioplast development and deetiolation, chloroplast biogenesis, chilling tolerance, and oxidative stress response.
