摘要
乙酰乳酸合成酶(ALS)是支链氨基酸生物合成途径中的关键酶之一,是磺酰脲类除草剂的作用靶标。针对目前市场上使用的4种ALS除草剂,对ALS抑制剂类除草剂的抗性杂草问题, ALS氨基酸序列中关键位点替换对ALS酶活性的影响与ALS基因编辑等方面的相关研究进展进行了概述。
Acetolactate synthase(ALS) is a key enzyme in the branched chain amino acid biosynthesis pathway,and it is an important target for sulfonylurea herbicides.This article is a brief overview of study about ALS inhibitor herbicides and resistance weeds problem,including ALS inhibitor herbicides used in commercial,the problem of resistance weeds to ALS herbicides,the effect of ALS enzyme activity resulting from the ALS amino acids subsititution,and ALS gene editing.
