ERF1 — Capsicum annuum

Summary

CaERF1 (T459_03263) on pepper chromosome 1 encodes an AP2/ERF domain-containing transcription factor with sequence-specific DNA binding activity. It is associated with the regulation of ethylene-mediated signaling, jasmonic acid and lignin anabolism, defense response, nitric oxide storage, fruit ripening, seed germination, and signal transduction, and localizes to the nucleus. The gene has been linked to fruit length and weight, heterosis, flavonoid content, seed viability, salt response, photosynthetic rate, and plant height. Studies of related genes in other species connect the family to root fresh weight, hydrogen peroxide and carotenoid content, fruit color and size, net photosynthetic and transpiration rates, water use efficiency, seed maturation, and stomatal resistance.
