Figure 5From: The adenylate cyclase gene MaAC is required for virulence and multi-stress tolerance of Metarhizium acridumExogenous addition of 8-Br-cAMP to the AC-RNAi mutant results in increased growth rates. The morphology of the wild type, knockdown control and AC-RNAi mutant colonies grown in the presence of 8-Br-cAMP (5 mM) were inoculated on PDA medium. These cultures were grown for 5 d prior to documentation. Scale bar: 0.5 cm.Back to article page
