A key enzyme in the shikimate pathway, 5-enolpyruvylshikimate-3-phosphate synthase (EPSPS) is primary target of broad-spectrum herbicide glyphosate. Identification new aroA genes coding for EPSPS with a high level glyphosate tolerance essential development glyphosate-tolerant crops. In present study, five bacterial was evaluated E. coli aroA-defective strain ER2799 and transgenic tobacco plants. All could complement ER2799, AM79 showed highest tolerance. Although treatment inhibited growth...
