Abstract
The recent availability of genome sequence information for the opportunistic pathogen Candida albicans has greatly facilitated the ability to perform genetic manipulations in this organism. Two important molecular tools for studying gene function are regulatable promoters for generating conditional mutants and fluorescent proteins for determining the subcellular localization of fusion gene products. We describe a set of plasmids containing promoter-GFP cassettes (PMET3-GFP, PGALI -GFP, and PPCK1-GFP), linked to a selectable nutritional marker gene (URA3). PCR-mediated gene modification generates gene-specific promoter, or gene-specific promoter-GFP, fusions at the 5′-end of the gene of interest. One set of primers can be used to generate three strains expressing a native protein of interest, or an amino-terminal GFP-tagged version, from three different regulatable promoters. Thus, these promoter cassette plasmids facilitate construction of conditional mutant strains, overexpression alleles and/or inducible amino-terminal GFP fusion proteins.
