Cyhalofop‐butyl resistance conferred by a novel Trp‐2027‐Leu mutation of acetyl‐CoA carboxylase and enhanced metabolism in Leptochloa chinensis

This study confirmed the first case of an arable weed species featuring cross-resistance to ACCase-inhibiting herbicides due to a novel Trp-2027-Leu mutation of ACCase. Target gene mutation and cytochrome P450s- and glutathione-S-transferases-involved enhanced metabolism may have simultaneously participated in the resistance of HFFD3 population to cyhalofop-butyl.
