Inactivation of the Catalytic Subunit of cAMP-Dependent Protein Kinase A Causes Delayed Appressorium Formation and Reduced Pathogenicity of Colletotrichum gloeosporioides

Figure 5

Progressive phases of C. gloeosporioides mutant Cgpkac1 and wild-type strain during conidial germination and appressorium formation. The image was captured using an Olympus phase contrast microscope (400x magnification) and a Nikon digital camera. Appressorium formation of 4-hour-old germlings on hydrophobic glass slide coated with rubber wax was observed at (a) 0 min; (b) 30 min; (c) 60 min; (d) 90 min; (e) 180 min. (a: appressorium; c: conidium; g: germ tube).
