Recently, the National Key Laboratory of Green Pesticides at CCNU, led by Professor Yang Guangfu, published an online research paper titled "An Artificially Evolved Gene for Herbicide-Resistant Rice Breeding" in PNAS. This study reports the discovery of a newly developed broad-spectrum herbicide resistance gene that confers resistance to HPPD herbicides in rice. This gene is of significant importance for crop breeding and holds promising potential for wide application. As a result, this project carries considerable theoretical and practical value.
Rice serves as the staple food for more than half of the world's population. Herbicides are the most economical and effective method for weed control in rice cultivation. However, prolonged use of herbicides can lead to the development of weed resistance, making the discovery and engineering of new genes for broad-spectrum herbicide resistance a critical challenge in molecular breeding research.
