ERF1 — Capsicum annuum

Summary

T459_03264 (ERF1, also known as CaERF13 or ERF13) on pepper chromosome 1 encodes an ethylene-responsive transcription factor 1 with an AP2/ERF domain, conferring sequence-specific DNA binding and transcription cis-regulatory region binding activities. It is associated with regulation of ethylene-mediated signaling, jasmonic acid biosynthesis, defense responses, fruit ripening, floral meristem determinacy, secondary shoot formation, and nitric oxide storage. The gene has been connected to fruit length and weight, plant height, photosynthetic rate, heterosis, flavonoid content, seed viability, and chilling tolerance. Studies of related genes in other species link the ERF1 family to net photosynthetic rate, transpiration rate, water use efficiency, stomatal resistance, salt response, and fruit size.
