The complete mitochondrial genome of Wiesnerella denudata (Mitt.) Steph. (Wiesnerellaceae, Marchantiophyta): large number of intraspecific variations on mitochondrial genomes of W. denudata.

Wiesnerella denudata (Mitt.) Steph. is a thallose liverwort distributed in Asian subtropical to tropical regions. It is the only one species in genus Wiesnerella and family Wiesnerellaceae. To investigate intraspecific variations on mitochondrial genomes of W. denudata, we completed mitochondrial genome of W. denudata. Its length is 185,640 bp, longer than that of the previously sequenced mitochondrial genome by 71 bp and contains 73 genes (41 protein-coding genes, 3 rRNAs, 28 tRNAs, and 1 pseudogene). A total of 149 single nucleotide polymorphisms (SNPs) and 3,033 insertions and deletions are identified, much higher than those of Marchantia polymorpha subsp. ruderalis and Riccia fluitans. Phylogenetic trees show that W. denudata is clustered with Monosolenium tenerum belonging to Monosoleniaceae.
