Targeted disruption of FocGCS affects conidiation, conidial germination, and conidial morphology of Fusarium oxysporum f. sp. cubense tropical race 4. a Conidial morphology of the WT, ∆FocGCS, and complemented strains. Blue fluorescence represents the number of fungal septa. Scale bars = 10 μm (upper) and 100 μm (bottom). b Conidial length examined by counting of at least 100 randomly selected conidia per three microscopy fields. The mean values ± SD were calculated from three independent experiments. c Conidia production of the indicated strains incubated for 5 days on PDA plates. d Conidial germination rate of the strains incubated on YEPD broth for 12 h. Germination of 100 conidia was randomly examined. Asterisks indicate significant differences from the WT group (Student’s t-test, ***P < 0.001)
