Abstract

To understand the differences in the organization of mitochondrial genomes of the very closely related Aspergillus niger and Aspergillus tubingensis species, we determined the complete genome sequence of the 1a mtDNA type of A. niger and 2b mtDNA type of A. tubingensis and now we provide a comparative analysis of the two mtDNAs. We found that (1) the organization (gene content and order) of the two genomes is almost identical and (2) the size difference between them is principally attributed to the different intron content of their cox1, atp9 and ndh4L genes.
