Abstract
A novel aroA gene encoding 5-enolpyruvylshikimate-3-phosphate synthase from Bacillus cereus was identified and overexpressed by genomic library construction and complementary screening. The enzyme was then purified to homogeneity. We also transformed the aroA B. cereus gene into Arabidopsis thaliana by a floral dip method, and demonstrated that transgenic A. thaliana plants exhibited significant glyphosate resistance compared with the wild type. These results strongly suggested that the strategy was highly efficient and advantageous for rapidly cloning aroA genes from microorganisms in natural environments.
