The complete mitochondrial genome of an Antarctic moss, Andreaea regularis Müll. Hal. 1890 (Andreaeaceae).

In the present study, we determined the complete mitochondrial genome of Müll. Hal. 1890, a lantern moss of the genus Hedw. (Andreaeaceae). The mitochondrial genome, with a total length of 118,833 bp, consists of 40 protein-coding genes, 3 ribosomal RNA genes, and 24 transfer RNA genes. A phylogenetic tree constructed with 19 complete mitochondrial genomes composed of liverworts, hornworts, and 15 mosses showed that Andreaeales formed the closest sister to Sphagnales before divergence of the remaining moss groups, indicating being one of the earliest mosses. Our findings could be beneficial to investigate the bryophyte evolution.
