摘要:
BACKGOUND: Acetohydroxyacid synthase (AHAS; EC 2.2.1.6) is the first common enzyme in the biosynthetic pathway leading to the branched-chain amino acids in plants and a wide range of microorganisms. With the long-term and wide application of AHAS inhibitors, weed resistance is becoming a global problem, which leads to an urgent demand for novel inhibitors to antagonize both wild-type and resistant AHAS. RESULTS: Pyrimidinyl salicylic acid derivatives, as one of the main classes of commercial AHAS herbicides, show potential anti-resistant bioact...
