英文摘要
Evolution of multiple herbicide resistance is widespread in Lolium rigidum in Australia. This resistance is very often endowed by enhanced rates of herbicide metabolism (metabolic resistance) involving cytochrome P450. This project aims to identify, clone and characterise important herbicide-metabolising P450 and other genes from multiple herbicide-resistant L. rigidum biotypes, and develop transcriptional and biochemical markers for metabolic resistance diagnosis. Herbicide-metabolising gene discovery, characterisation and marker development will greatly extend the currently limited knowledge and understanding of metabolic resistance and help achieve sustainable weed management.
