In fungi, ambient pH sensing involves the activation of the Pal/PacC signalling pathway. In
the dermatophyte Trichophyton rubrum, pH-dependent secretion of keratinases, which are
major virulence determinants, is affected by disruption of the pacC gene. Here, the

Abstract
In fungi, ambient pH sensing involves the activation of the Pal/PacC signalling pathway. In the dermatophyte Trichophyton rubrum, pH-dependent secretion of keratinases, which are major virulence determinants, is affected by disruption of the pacC gene. Here, the transcription profiling of the genes coding for N- and O-linked mannosyltransferases, enzymes involved in protein glycosylation, was evaluated in T. rubrum in response to disruption of the pacC gene and growth in keratin, glucose, and glucose plus glycine. We show that transcription of these mannosyltransferase genes is affected by nutrients at acidic pH and by PacC.
