The complete chloroplast genome of Mnium marginatum (With.) P. Beauv.

Mnium is the type genus of the family Mniaceae, the species' richest family of order Bryales (Bryophyte). Mnium marginatum is widely distributed worldwide. The complete chloroplast genome of M. marginatum was sequenced by high-throughput sequencing technology. The chloroplast genome is 124,935 bp in length with a quadripartite structure. The two inverted repeat regions are 9,910 bp long and separated by a large single-copy region of 86,572 bp and a small single-copy region of 18,543 bp. Based on the chloroplast genome data of 11 bryophytes downloaded from GenBank and one acquired in this study, phylogenetic trees were constructed.
