Copper is an essential element for microbes as it involved in many redox reactions. Numerous resistance systems have been evolved to maintain copper homeostasis under stress conditions. These are responsible the influx and efflux of ions cells. In phytopathogenic bacteria, play roles during disease development plants. Copper-based chemicals extensively used control diseases caused by which lead...
