Abstract
To date, only aroA variants derived from Agrobacterium tumefaciens CP4 have been used to generate the commercial glyphosate-resistant crops currently available in the market. Therefore, it is of interest to increase aroA gene diversity and seek new glyphosate-tolerant genes for developing glyphosate-tolerant crops. In this study, a novel aroA gene encoding 5-enolpyruvylshikimate-3-phosphate synthase from Paracoccus denitrificans was isolated using the genomic library construction and complementary screening. Furthermore, the transgenic Arabidopsis plants with the aroA gene from P. denitrificans were obtained to confirm the potential of the novel aroA gene in developing glyphosate-resistant crops.
