ETHYLENE-RESPONSE-FACTOR1 (ERF1) IN PLANTS

摘要

The invention provides an isolated nucleic acid encoding Ethylene Response Factor 1 (ERF1), an early responsive gene, encoding a GCC-box binding protein in the ethylene gas signaling pathway in plants. Also provided and characterized is the peptide ERF1, as well as methods of using ERF1 or its expression product to modulate the response in plants or plant cells to ethylene. Moreover, because ERF1 acts downstream of EIN3 and all previously identified members of the signaling pathway, and because constitutive expression of ERF1 results in the modulation of a variety of ethylene response genes and phenotypes, the invention provides novel and useful methods for regulating the ethylene signaling pathway.
