The complete mitochondrial genome of R hodotorula taiwanensis RS 1, an aluminum‐tolerant B asidiomycota fungus, was determined and compared with the known mitochondrial genomes of 12 B asidiomycota species. The mitochondrial genome of R . taiwanensis RS 1 is a circular DNA molecule of 40,392 bp and encodes the typical 15 mitochondrial proteins, 23 tRNA s, and small and large rRNA s as well as 10 intronic open reading frames. These genes are apparently transcribed in two directions and do not show syntenies in gene order with other investigated B asidiomycota species. The average G+C content (41%) of the mitochondrial genome of R . taiwanensis RS 1 is the highest among the B asidiomycota species. Two introns were detected in the sequence of the atp9 gene of R . taiwanensis RS 1, but not in that of other B asidiomycota species. R hodotorula taiwanensis is the first species of the genus R hodotorula whose full mitochondrial genome has been sequenced; and the data presented here supply valuable information for understanding the evolution of fungal mitochondrial genomes and researching the mechanism of aluminum tolerance in microorganisms.
