Amino acids are crucial to plants and play an important role in plant's biological process. Plants must synthesize all needed amino acids. Once the amino acid biosynthesis being inhibited, the plants will be difficult to survive, hence the key enzymes concerned with the amino acid biosynthesis remain to be the important targets during the development of new herbicides. Herbicides designated as amino acid biosynthesis inhibitors take up a large proportion among the commercialized herbicides，at the same time, along with the development of plant transgenic techniques, a great deal of transgenic plants tolerant to herbicidal inhibitors of amino acid biosynthesis come out and become the main body of transgenic herbicide-tolerant plants gradually. This article reviewed the currently commercialized herbicidal inhibitors of amino acid biosynthesis，functional mechanism and the advance in transgenic herbicide-tolerant plants.
