The mitogenome of , a desiccation-tolerant moss.

Bryophytes are the earliest plant group on Earth. They are a fundamental component of many ecosystems around the World. Some of their main roles are related to soil development, water retention, and biogeochemical cycling. Bryophytes include liverworts, hornworts, and mosses. The sequencing of chloroplast and mitochondria genomes has been useful to elucidate the taxonomy of this heterogeneous plant group. To date, despite their ecological importance only 41 mosses mitogenomes have been deposited in the GenBank. Here, the complete mitochondria genome sequence of , a moss of the Pottiaceae family isolated in Tlaxcala, Mexico, is reported. The mitochondrial genome size of comprises 105,495 bp and contains the groups of genes described for other bryophytes mitogenomes. Our phylogenetic analysis shows that during the evolution of the mosses' mitogenome, , , , and genes were lost independently in several lineages. The complete mitogenome sequence reported here would be a useful tool for our comprehension of the evolutionary and population genetics of this group of plants.
