Knockdown of pyr4 using P _tcu1 -driven RNAi system was responsive to copper in agar plate. Equal amount of conidia spores from QM9414 and the P _tcu1 –pyr4^KD strain was inoculated on minimal media agar plate containing 2% (w/v) glucose as a sole carbon source. a No copper and uridine was present in the media. Twenty μM copper (b) and 10 mM uridine (c) were added into the minimal media agar plates, respectively
