Abstract

We present the nucleotide sequence of a 5207-bp-long region of the mitochondrial genome of the dermat-ophyte Trichophyton rubrum. This represents about 1/5th of the total genome and extends a previous study. From the 5′ end of the present sequence, the order of genes is as follows: the end of the ND4 gene, the gene coding for subunit 6 of ATPase, the gene coding for the small ribosomal RNA (SSU rRNA), the tyrosyl tRNA gene, the ND6 gene, the COXIII gene, the ATPase 8 subunit gene and a cluster of tRNAs genes corresponding respectively to the lysine, glutamine, asparagine, isoleucine and tryptophan isoacceptors. The interesting features of this region are its compact organisation, the presence of subunit 8 of the ATPase gene and the secondary structure of SSU rRNA which is close to that of Aspergillus nidulans. On the basis of the order of the genes, which is essentially similar to that of A. nidulans, we can also assume that the LSU rRNA subunit gene should be just upstream of this sequenced region.
