The complete mitochondrial genome of the important phytopathogen Nectria cinnabarina (Hypocreales, Ascomycota)

Abstract

The complete nucleotide sequence of the mitochondrial genome of the important phytopathogic fungus Nectria cinnabarina was determined using the next-generation sequencing technology. The circular molecule is 69 895 bp long with a GC content of 28.71%. 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. Compared with previously sequenced mitochondrial genomes of the other members of Nectriaceae, the composition and order of the protein and rRNA genes are highly conserved; however, the quantity and order of tRNA genes are different. The phylogenetic analysis confirmed N. cinnabarina as a basal lineage in Nectriaceae. The mitochondrial genome of N. cinnabarina will contribute to the understanding of phylogeny and evolution of Nectriaceae and Hypocreales.
