The complete chloroplast genome of an Antarctic moss, (Hedw.) J.R.Spence & H.P.Ramsay (Bryaceae), and phylogenetic analysis.

(Hedw.) J.R.Spence & H.P.Ramsay (Bryaceae) is a bipolar and one of the most widespread species within Antarctica, exhibiting a ubiquitous presence along the Antarctic Peninsula. This study analyzed its chloroplast genome, which is 123,172 bp in length, and consists of 82 protein-coding genes, four ribosomal RNA genes, and 31 transfer RNA genes. A phylogenetic tree, constructed using 58 conserved orthologous protein-coding genes from 19 complete chloroplast genomes of the class Bryopsida, confirmed that belongs to clade Bryaceae. Within this clade, diverged from the clade containing and . This study contributes to enriching chloroplast genome resources for the family Bryaceae and the genus . Such advancement could facilitate future genetic investigations aimed at conserving and exploiting Antarctic bryophytes.
