A centromere has been isolated from Candida glabrata by functional selection based on the lethality of the SUP11 gene at high copy number. Nucleotide sequence analysis revealed a centromeric structure similar to that of Saccharomyces cerevisiae: the two highly conserved elements CDEI (8 bp) and CDEIII (26 bp) are separated by a 79-bp A+T-rich element, CDEII. Three centromere-bearing plasmid vectors with different selection markers have been constructed. These plasmids were highly stable in mitosis (< 1% loss rate per generation) and exist in one or two copies per cell.

In this study, we investigated the interactions between and , , , and in mixed infections. Initially, these interactions were studied qualitatively and quantitatively in dual-species biofilms formed in vitro. The MTT assays, determination of the total CFU/mL, and SEM analysis showed that interacted differentially with the other spp.

Although the mitochondrial genome is an attribute of all eukaryotes, some yeast species (called petite-positive) can replicate without mitochondrial DNA (mtDNA). Strains without mtDNA (known as rho mutants or petite mutants) are respiration-deficient and require fermentable carbon sources (such as glucose) for their metabolism. However, they are compromised in many aspects of fitness and competitiveness.
