ERF1 — Capsicum annuum

Summary

CaERF1 (T459_03260) on pepper chromosome 1 encodes an ethylene-responsive transcription factor 2 with an AP2/ERF domain, a sequence-specific DNA-binding protein that localises to the nucleus. The gene is associated with regulation of ethylene-mediated signalling, jasmonic acid anabolism, defense response, fruit ripening, and NO storage. It has been linked to fruit length and weight, plant height, photosynthetic rate, flavonoid content, heterosis, and seed viability. Studies of related genes in other species connect the family to root fresh weight, fruit color and size, carotenoid content, net photosynthetic rate, transpiration rate, water use efficiency, stomatal resistance, salt response, hydrogen peroxide content, and seed maturation.
