Abstract
Complete nucleotide sequence of the 78,447 bp mitochondrial genome of the white-rotting fungus Ganoderma meredithiae Adask. & Gilb. has been determined by next-generation sequencing technology. The circular molecule encodes a set of mitochondrial protein and RNA genes, including 15 conserved proteins, 29 tRNAs, large and small ribosomal RNAs, and 18 homing endonucleases, with a GC content of 26.14%. All structural genes are located on the same strand except trnW-CCA. Compared with previously sequenced mtDNAs of G. lucidum and G. sinense, the gene order of protein and rRNA genes among the three mitogenomes is highly conserved; however, the tRNA composition is slightly different. The mitochondrial genome of G. meredithiae will contribute to understanding the phylogeny and evolution of Ganoderma and Ganodermataceae, the group containing many species with high medicinal values.
