ERF1 — Capsicum annuum

Summary

CaERF1 (T459_08797) on pepper chromosome 3 encodes an ethylene-responsive transcription factor 1B, a member of the AP2/ERF domain family with sequence-specific DNA binding and transcription factor activity. The gene is associated with regulation of ethylene-mediated signaling, jasmonic acid anabolism, defense responses, nitric oxide storage, fruit ripening, and signal transduction, and its product localizes to the nucleus. CaERF1 has been linked to several agronomically important traits, including fruit length, fruit weight, plant height, seed viability, flavonoid content, and heterosis. Related genes in other species, such as ERF1, ERF2, ERF3, ERF4, PTI5, and PTI6, are linked by sequence similarity.
