Figure Lengend Snippet: A. brasilense AR mutant exhibits elevated levels of intracellular c-di-GMP. Colony morphology of wild-type A. brasilense Sp7 ( A ) and the AR mutant ( B ) expressing a c-di-GMP biosensor (pFY4535). Cultures were grown for five days at 30 °C on Nfb∗ agar supplemented with KNO 3 . The intracellular c-di-GMP concentration is proportional to the expression of TurboRFP (red), resulting in a red colony color. The AR mutant's more intense coloration indicates higher c-di-GMP accumulation than in the WT. Representative fluorescence microscopy of individual WT and AR mutant cells. Images were captured on a Nikon Eclipse TE2000-U microscope using the following excitation/emission wavelengths: 489/519 nm for AmCyan (green) and 553/574 nm for TurboRFP (red). Gray images are intensity surface plots corresponding to the fluorescence emitted by TurboRFP. Images were processed using Nikon NIS Elements software. All images shown are representative of three independent experiments. Scale bars, 10 mm (colonies); 10 μm (individual cells).
