Characterizing Candida glabrata Pdr1, a Hyperactive Transcription Factor Involved in Azole Resistance

Abstract

This chapter illustrates how to prepare isogenic strains carrying gain-of-function forms of transcription factor Pdr1 in the human pathogen Candida glabrata. Simple steps are described that lead from a characterized plasmid-borne PDR1-GOF allele to its integration into the yeast genome in a markerless manner. Pdr1-GOF strains constructed by this approach are suitable for virulence studies in an animal host.
