NTRC — Arabidopsis thaliana

Summary

AT2G41680 (NTRC) in Arabidopsis thaliana encodes a protein with thioredoxin reductase and ferredoxin-NADP reductase domains, classified as EC 1.8.1.9, and exhibits thioredoxin reductase (NADPH), oxidoreductase, peroxidase, and salicylic acid binding activities. The NTRC protein localises to chloroplast stroma, thylakoids, and stromules. It is associated with C4 photosynthesis, photosynthetic electron transport, regulation of chlorophyll and starch biosynthesis, tetrapyrrole and ATP anabolism, plastid gene expression and translation, the pentose-phosphate shunt, and oxidative stress responses. The gene is linked to numerous agronomic traits including photosynthetic rate and efficiency, quantum yield, photochemical and non-photochemical quenching, starch and protein content, leaf growth and size, biomass yield, and tolerance to salt, drought, cold, freezing, and oxidative stress. Studies of related genes in other species connect the family to disease resistance, fruit ripening, and starch accumulation.
