ATF1 — Cucumis melo

Summary

MELO3C034498.2, also known as CmATF1, encodes a thioredoxin-like protein with protein-disulfide reductase, peroxidase, and enzyme activator and inhibitor activities, and binds salicylic acid. It is associated with cell redox homeostasis, responses to cold and light intensity, and regulation of carbohydrate metabolism. The protein localizes to chloroplast thylakoids, stromules, the chloroplast envelope, apoplast, and cytosol. CmATF1 is linked to plant growth, photosynthetic electron transport rate, photosynthesis, antioxidant response, altered redox behavior under high light/dark conditions, and reduced fresh weight and photosynthetic pigment content. Studies of related genes in other species connect this family to carbon dioxide fixation, photosynthetic efficiency, and herbicide sensitivity and resistance.
