ATF1 — Cucumis melo

Summary

MELO3C035601.2, also known as CmATF1, encodes a protein with thioredoxin and zinc-finger domains that exhibits protein-disulfide reductase, peroxidase, enzyme activator, enzyme inhibitor, and salicylic acid binding activities. This melon gene on chromosome 13 is associated with cell redox homeostasis, response to cold, and response to light intensity. It localizes to multiple chloroplast compartments including the thylakoid, stroma, and envelope, as well as the stromule, apoplast, and cytosol. CmATF1 is associated with 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. Related genes in other species are linked to carbon dioxide fixation, photosynthetic efficiency, and herbicide sensitivity.
