Metabolic activities in ΔatfA resting conidia. a Ergosterols were stained by filipin in the resting conidia of A. fumigatus Afs35 (WT), ΔatfA, and the complemented strain (Co-atfA). The test was repeated twice, and more than three sections were observed. The representative photos were shown. b The resazurin assay indicates metabolic activity in the ΔatfA resting conidia, which are without nutrients. c The XTT assay shows metabolic activity in the ΔatfA resting conidia, which are without nutrients
