ERF1 — Capsicum annuum

Summary

T459_14861 (CaERF2, ERF1) on pepper chromosome 5 encodes an ethylene-responsive transcription factor 1 with an AP2/ERF DNA-binding domain. The gene product localises to the nucleus and has sequence-specific DNA binding and transcription cis-regulatory region binding activities. CaERF2 is associated with regulation of the ethylene-mediated signalling pathway, jasmonic acid anabolism, defence response, fruit ripening, seed germination, and nitric oxide storage. It has been connected to fruit length, fruit weight, flavonoid content, seed viability, plant height, photosynthetic rate, heterosis, and salt response. Related genes in other species link the family to salt tolerance, net photosynthetic rate, transpiration rate, water use efficiency, stomatal resistance, and fruit size.
