| Abstract: | 1 - aminocyclopropane - 1 - carboxylate (ACC) deaminase was one of vital enzymes in certain plant growth promoting rhizohacteria (PGPR), which regulated ethylene production by metabolizing ACC (an immediate precursor of ethylene biosynthesis in higher plants) into α- ketohutyrate and ammonia.Decreased ethylene levels allowed the plant to be more resistant to a wide variety of environmental stresses.The mechanisms of ACC deaminase, the factors affecting their enzymatic activity, and information regarding the affect of this enzyme on different plants were reviewed in the paper.Future perspectives in ACC deaminase research were also discussed, which included a wide sources of the enzyme to get and study, the quantification of colonization ability of the PGPR containing ACC deaminase,the application of the enzyme in phytoremediation, and the establishment of the enzyme transgenic plants models. |
