In this work we cloned CdPHR1 and CdPHR2 from the human fungal pathogen Candida dubliniensis. The two genes are homologues to the pH-regulated genes PHR1 and PHR2 from Candida albicans. The pH-dependent pattern of expression of CdPHR1 and CdPHR2 was conserved in C. dubliniensis. CdPHR1 could be shown to be functionally equivalent to PHR1. The pH-regulated mode of expression was maintained when CdPHR1 was integrated in C. albicans. This indicates a fundamentally similar mode of expressional regulation in the two species. CdPHR1 was furthermore capable of reversing the aberrant phenotype of a Saccharomyces cerevisiae GAS1 deletion mutant. In this species, however, expression of CdPHR1 was no longer under control of the external pH. Expression of CdPHR1 was not detected when it was introduced into Aspergillus nidulans. In conclusion, C. dubliniensis and C. albicans respond to changes in the environmental pH with a change in cell shape and differential gene expression.
