Fig. 6

CgHOS2 is required for normal appressorium formation and penetration. a Microscopy observations of conidia incubated on polyester for 10 and 20 h. The black arrows indicate appressoria (AP) and germ tubes (GT). Bar = 50 μm. b Microscopy observations of conidia incubated on onion epidermis for 6 and 8 h. The red arrows indicate invasive hyphae (IH). c Conidial germination and appressorium formation rates on polyester. d Conidial germination and appressorium formation rates on onion epidermis. e Colony morphology of fungi cultured on cellophane for 3 and 6 days. The cellophane membrane was removed after incubation for 3 days, followed by incubation for another 3 days. f Microscopy observations of conidia incubated on cellophane for 6 h. g Conidial germination rates on cellophane for 6 h. The values are shown as the means ± standard deviations (SD) of three groups of samples. The columns with different letters indicate significant differences (P < 0.05)
