ATH2 — Glycine max

Summary

GLYMA_09G240800V4 (GmATH2, also known as GmTRX2 or GmTRXH2) on soybean chromosome 9 encodes a thioredoxin H-type protein with oxidoreductase activity acting on sulfur-group donors with disulfide as acceptor, protein-disulfide reductase activity, and enzyme inhibitor activity. This gene is associated with diverse biological processes including acquisition of desiccation tolerance, response to water, photoprotection, nitrogen fixation, detoxification, fermentation, hormone metabolism (auxin and salicylic acid), and water transport. It has been linked to agronomically important traits such as harvest index, seed weight, amino acid content, nitrogen content, root length, and drought tolerance, as well as cold tolerance and seed respiration. The protein localizes to mitochondria, cytosol, and cytoplasm. Studies of related genes in other species connect the thioredoxin family to methionine sulfoxide assimilation, sulfate assimilation, and cell cycle regulation.
