ATF1 — Cucumis melo

Summary

MELO3C029053.2 (CmATF1) on melon chromosome 2 encodes a thioredoxin-like protein with protein-disulfide reductase, peroxidase, and enzyme activator/inhibitor activities, and binds salicylic acid. The gene is associated with cell redox homeostasis, regulation of carbohydrate metabolism, and responses to cold and light intensity. Its product localizes to the chloroplast thylakoid, stroma, envelope, stromule, apoplast, and cytosol. CmATF1 is associated with plant growth, photosynthetic electron transport rate, photosynthesis, antioxidant responses, altered redox behavior under high/low light, and reduced fresh weight and photosynthetic pigment content. Related genes in other species link the thioredoxin f family to carbon dioxide fixation, photosynthetic efficiency, growth, and herbicide sensitivity/resistance.
