Mitogenomics and mitochondrial gene phylogeny decipher the evolution of Saccharomycotina yeasts.

ABSTRACT: Saccharomycotina yeasts belong to diverse clades within the kingdom of fungi and are important to human everyday life. This work investigates the evolutionary relationships among these yeasts from a mitochondrial (mt) genomic perspective. A comparative study of 155 yeast mt genomes representing all major phylogenetic lineages of Saccharomycotina was performed, including genome size and content variability, intron and intergenic regions' diversity, genetic code alterations, and syntenic variation. Findings from this study suggest that mt genome size diversity is the result of a ceaseless random process, mainly based on genetic recombination and intron mobility. Gene order analysis revealed conserved syntenic units and many occurring rearrangements, which can be correlated with major evoluti
