The complete chloroplast genome of an Antarctic moss, Ptychostomum pseudotriquetrum (Hedw.) J.R.Spence & H.P.Ramsay (Bryaceae), and phylogenetic analysis.
Ptychostomum pseudotriquetrum (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 P. pseudotriquetrum belongs to clade Bryaceae. Within this clade, P. pseudotriquetrum diverged from the clade containing Anomobryum gemmigerum and Bryum argenteum. This study contributes to enriching chloroplast genome resources for the family Bryaceae and the genus Ptychostomum. Such advancement could facilitate future genetic investigations aimed at conserving and exploiting Antarctic bryophytes.
