AIM Capl p, encoded by CAP1 in Candida albicans, is highly homologous to Saccharomyces cerevisiae transcription factor Yapl p. It has been associated with tolerance to oxidative stress and resistance to a variety of toxicants previously. We used homemade microarray to reveal Capl p related genes in a broad spectrum as well as to lucubrate the functions of Capl p. METHODS Microarray analysis was used to identify differentially expressed genes between CAP1 deletion strain CJD21 and its parental strain CAI4. CAP1 over-expression strain was constructed to confirm the relationship between CAP1 and some differentially expressedgenes. Bioinformatics was applied to reveal promoters with Capl p binding site as well as the clusters of differentially expressed genes. RT-PCR and drug efflux analysis were used to lucubrate the functions of Caplp in Candida albicans.
