Flavin Mononucleotide-Based Fluorescent Protein as an Oxygen-Independent Reporter in Candida albicans and Saccharomyces cerevisiae▿ †

摘要

Hypoxia is encountered frequently by pathogenic and apathogenic fungi. A codon-adapted gene encoding flavin mononucleotide-based fluorescent protein (CaFbFP) was expressed in Candida albicans and Saccharomyces cerevisiae. Both species produced CaFbFP and fluoresced even during hypoxia, suggesting that oxygen-independent CaFbFP is a useful, novel tool for monitoring hypoxic gene expression in fungi.
