Transcription factor CCG-8 as a new regulator in the adaptation to antifungal azole stress.

ABSTRACT: Antifungal azoles are widely used for controlling fungal infections. Fungi are able to change the expression of many genes when they adapt to azole stress, and increased expression of some of these genes can elevate resistance to azoles. However, the regulatory mechanisms behind transcriptional adaption to azoles in filamentous fungi are poorly understood. In this study, we found that deletion of the transcription factor gene ccg-8, which is known to be a clock-controlled gene, made Neurospora crassa hypersensitive to azoles. A comparative genome-wide analysis of the responses to ketoconazole of the wild type and the ccg-8 mutant revealed that the transcriptional responses to ketoconazole of 78 of the 488 transcriptionally ketoconazole-upregulated genes and the 427 transcriptionally ketoco
