Project description:Diutina catenulata is an ascomycetous yeast, that is regularly fluconazole-resistant and increasingly reported as the cause of invasive infection in humans. Here, we describe the de novo genome assembly of the clinical D. catenulata type-strain CBS565 and provide insights into the genome and compared it to an Illumina-sequenced environmental strain.

Genome analysis of the yeast Diutina catenulata, a member of the Debaryomycetaceae/Metschnikowiaceae (CTG-Ser) clade.

Project description:Diutina catenulata (Candida catenulata) is an ascomycetous yeast that has been isolated from humans, animals and environmental sources. The species is a contaminant of dairy products, and has been linked to superficial and invasive infections in both humans and animals. Previous phylogenetic analyses have assigned the species to the Saccharomycetales, but failed to identify its specific clade. Here, we report the genome sequence of an environmental isolate of D. catenulata. Examination of the tRNA repertoire and coding potential of this species shows that it translates the CUG codon as serine and not leucine. In addition, two phylogenetic analyses using 204 ubiquitous gene family alignments and 3,826 single-copy genes both confirm the placement of the species in the Debaryomycetaceae/Metschnikowiaceae, or CTG-Ser clade. The sequenced isolate contains an MTLα idiomorph. However, unlike most MTL loci in related species, poly (A) polymerase (PAP) is not adjacent to MTLα1.
