Tribenuron-methyl resistance in Capsella bursa-pastoris: the co-existence of ALS target enzyme mutation (Pro-197-Ser) and overexpression of GSTF12 and ADP/ATP carrier protein

Abstract

Capsella bursa-pastoris, a prevalent wheat-field weed in China, demonstrates substantial resistance to tribenuron-methyl, a herbicide-targeting acetolactate synthase (ALS). Understanding weed herbicide-resistance mechanisms is crucial for managing resistant weed populations. However, the genes potentially involved in nontarget-site resistance (NTSR) in herbicide-resistant C. bursa-pastoris remain poorly understood and require further investigation. This research aimed to elucidate the resistance level and underlying mechanisms of a field population (R) from Shandong Province, China, to tribenuron-methyl.
