摘要

Candida parapsitosis species complex includes three closely related species, namely C. parapsilosis (sensu stricto). C. orthopsitosis. and C. metapsilosis. Unlike most other yeast lineages, members of this species complex possess a linear mitochondrial genome. Yet, its circularized mutant form was identified in strains of C orthopsilosis and C. metapsilosis. To investigate the underlying variability, we performed comparative analyses of the complete mitochondrial DNA sequences in a collection of strains. Our results demonstrate that in contrast to C. parapsitosis and C. metapsilosis, C orthopsilosis exhibits remarkably high nucleotide diversity whose pattern is consistent with intraspecific genetic exchange.
