The complete mitochondrial genome of the important mycoparasite Clonostachys rosea (Hypocreales, Ascomycota)

AbstractThe complete nucleotide sequence of mitochondrial genome of the important mycoparasitic fungus Clonostachys rosea was determined using the next-generation sequencing technology. The circular molecule is 40,921 bp long with a GC content of 27.90%. Gene prediction revealed 42 genes encoding 15 conserved proteins, 25 tRNAs, the large and small ribosomal RNAs. All genes are located on the same strand. It is found to be similar to the previously sequenced mitochondrial genomes of Acremonium chrysogenum and Nectria cinnabarina. The differences lie in the copy number of trnG-UCC and locations of trnN-GUU and cox2. The phylogenetic analysis confirmed C. rosea as a sister taxon of A. chrysogenumin (Bionectriaceae). The mitochondrial genome of C. rosea will contribute to the understanding of phylogeny and evolution of Hypocreales.
