Abstract excerpt

Descurainia sophia, an invasive weed in wheat fields of China, has developed notable resistance to the acetolactate synthase (ALS)-inhibiting herbicide tribenuron-methyl. In this study, a suspected resistant population (R) of D. sophia was investigated to assess its resistance level and elucidate the underlying mechanisms. Whole-plant bioassays revealed that the R population exhibited a 35.20-fold higher...
