ATF1 — Cucumis melo

Summary

MELO3C027980.2, also known as CmATF1, encodes a protein with a thioredoxin domain and leucine-rich repeats, possessing protein-disulfide reductase, peroxidase, and salicylic acid binding activities. 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, and the apoplast. CmATF1 is associated with plant growth, photosynthetic electron transport rate, photosynthesis, antioxidant responses, and altered redox behavior under high light or dark conditions, as well as reduced fresh weight and photosynthetic pigment content. Studies of related genes in other species connect the family to carbon dioxide fixation, photosynthetic efficiency, and herbicide sensitivity or resistance.
