Abstract

<abstract abstract-type="main" id="mbo374-abs-0001"> <title>Abstract</title> <p>The complete mitochondrial genome of <italic>Rhodotorula taiwanensis </italic>RS1, an aluminum‐tolerant <italic>Basidiomycota</italic> fungus, was determined and compared with the known mitochondrial genomes of 12 <italic>Basidiomycota</italic> species. The mitochondrial genome of <italic>R. taiwanensis </italic>RS1 is a circular DNA molecule of 40, 392 bp and encodes the typical 15 mitochondrial proteins, 23 tRNAs, and small and large rRNAs 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 <italic>Basidiomycota</italic> species. The average G+C content (41%) of the mitochondrial genome of <italic>R. taiwanensis </italic>RS1 is the highest among the <italic>Basidiomycota</italic> species. Two introns were detected in the sequence of the <italic>atp9</italic> gene of <italic>R. taiwanensis </italic>RS1, but not in that of other <italic>Basidiomycota</italic> species. <italic>Rhodotorula taiwanensis</italic> is the first species of the genus <italic>Rhodotorula</italic> 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.</p> </abstract>
