ERF1 — Capsicum annuum

Summary

CaERF1 (T459_03261) on pepper chromosome 1 encodes a DNA-binding transcription factor of the AP2/ERF family, localised to the nucleus. It is associated with regulation of ethylene-mediated signalling, jasmonic acid anabolism, lignin anabolism, defense response, fruit ripening, seed germination, floral meristem determinacy, regulation of secondary shoot formation, NO storage, and signal transduction. The gene has been connected to fruit length and weight, plant height, photosynthetic rate, flavonoid content, heterosis, seed viability, and salt response. Studies of related genes in other species link the family to root fresh weight, hydrogen peroxide and carotenoid content, fruit color and size, net photosynthetic and transpiration rates, water use efficiency, stomatal resistance, and seed maturation.
