ERF3 — Capsicum annuum

Summary

CaERF3 (T459_14985) on pepper chromosome 5 encodes an ethylene-responsive transcription factor 5 with an AP2/ERF DNA-binding domain and exhibits sequence-specific DNA binding, transcription factor activity, protein kinase activity, and phosphatase binding. This gene is associated with responses to oxygen levels, high light intensity, freezing, chitin, and nematodes, as well as regulation of ethylene signaling, jasmonic acid-mediated systemic resistance, stomatal patterning and closure, root meristem size, unidimensional cell growth, and phloem or xylem histogenesis. It is linked to traits including seed size, leaf morphology, photosynthetic rate, salt response, proline content, phosphorus uptake, UV-B light sensitivity, and wheat powdery mildew disease response. Localization evidence connects the product to the nucleus, cytosol, stress granules, and the preprophase band. Related genes in other species link the ERF family to cadmium tolerance, stress priming, and resistance to Botrytis cinerea.
