MAR1 — Pisum sativum

Summary

PsMAR1 (MAR1) on chromosome 5LG3 encodes a protein with BamA-like and D15-like domains, annotated with glycolipid binding, chloroplast targeting sequence receptor activity, transmembrane signaling receptor activity, GPCR activity, polygalacturonate 4-alpha-galacturonosyltransferase activity, protein translocase activity, GTPase activity, GTP binding, transglycosidase activity, identical protein binding, and protein binding. It is associated with the Toc complex, chloroplast outer membrane, chloroplast envelope, plastid, and other endomembrane compartments. The gene is linked to etioplast and chloroplast organization, protein import and targeting, regulation of photosynthesis, cellular response to cold, transition to reproductive phase, and homogalacturonan biosynthesis. Traits connected to MAR1 include linolenic and oleic acid content, chlorophyll content, plastid and chloroplast development, pollen fertility restoration, flowering time, root thickness, disease tolerance, and plant growth. Related genes in other species are linked to etioplast development and deetiolation.
