Abstract

Fungal growth and development depend on adaptation to the particular pH of their environment. Ambient pH sensing implies the activation of thepacCsignaling pathway, which then acts as a critical regulator for different physiological conditions. The PacC transcription factor may also be associated with the control of salt stress tolerance. In a pH-dependent manner, salinity stress is surpassed by changes in gene expression and coordinated activation of other signaling pathways, thus permitting survival in the challenging environment. In this study, we assessed the regulatory role ofTrichophyton interdigitalePacC in response to pH variation and salinity stress. By employing gene expression analysis, we evaluated the influence of PacC in the modulation of salt stress-related genes, including the transcription factorscrz1,egr2, and the MAP kinasehog1in the dermatophyteT. interdigitale. In our analysis, we also included the evaluation of a potassium/sodium efflux P-type ATPase aiming to identify the role of PacC on its ion pumping activity.Here we demonstrated that salinity stress and buffered pH conditions might affect thepacCgene modulation in the dermatophyteT. interdigitale.
