Expression of acetohydroxyacid synthase isozyme genes ilvBN, ilvGM, ilvIH and their resistance to AHAS-inhibitor herbicides
乙酰羟酸合成酶同工酶基因ilvBN、ilvGM和ilvIH的表达及对除草剂抗性的比较

Acetohydroxyacid synthase (AHAS) catalyses the first reaction in the pathway for synthesis of the branched-chain amino acids. AHAS is the target for sulfonylurea, imidazolinone and other AHAS-inhibitor herbicides. Herbicides-resistant AHAS genes have potential application in plant transgenetic engineering and development of new generation herbicide. The AHAS isozyme genes ilvBN, ilvGM and ilvIH were cloned from metsulfuron-methyl resistant strain Klebsiella sp. HR11 and metsulfuron-methyl sensitive strain K...
