Activation of cAMP signalling pathway by mrPDE knockout. a Colony morphology of WT and ΔmrPDE strains. The strains were cultivated on GM plates at 30 °C for 10 days. The cAMP concentration (b), relative PKA kinase activity (c), and DCW (d) of WT, ΔmrPDE and CΔmrPDE strains. Experiments were carried out in three replicates
