Antifungal treatment is often ineffectual, partly because of biofilm formation. In this study, by using a combined forward and reverse genetic strategy, we identified that nucleus-localized AfSsn3 and its partner AfSsn8, which constitute a Cdk8-cyclin pair, are required for azole resistance inAspergillus fumigatus . Deletion ofAfssn3 led to increased absorption and utilization of glucose and amino acids. Interestingly, absorption and utilization of glucose accelerated the extracellular polysaccharide formation, while utilization of the amino acids serine, threonine, and glycine increased sphingolipid pathway intermediate accumulation. In addition, the absence ofAfssn3 induced the activity of the efflux pump proteins. These factors indicate the mature biofilm is responsible for the major mechanisms ofA. fumigatus resistance to azoles in the ΔAfssn3 mutant. Collectively, the loss ofAfssn3 led to two “barrier” layers between the intracellular and extracellular spaces, which consequently decreased drug penetration into the cell.
