ATF1 — Cucumis melo

Summary

MELO3C032626.2, also known as CmATF1, encodes a thioredoxin-domain protein with protein-disulfide reductase, peroxidase, and enzyme activator/inhibitor activities, and binds salicylic acid. In melon, this gene is associated with cell redox homeostasis, responses to cold and light intensity, and regulation of carbohydrate metabolism. Its product localizes to plastids, including the chloroplast thylakoid, stroma, envelope, and stromule, as well as the apoplast and cytosol. CmATF1 is associated with plant growth, photosynthesis, photosynthetic electron transport rate, antioxidant responses, altered redox behavior under high light/dark conditions, and reduced fresh weight and photosynthetic pigment content. Studies of related genes in other species connect the family to carbon dioxide fixation, photosynthetic efficiency, herbicide sensitivity and resistance, and growth and development traits.
