The complete chloroplast genome of Pterobryopsis orientalis (Pterobryaceae, Hypnales) and its phylogenetic implications

Abstract

Pterobryopsis orientalis (Müll. Hal.) M. Fleisch. 1917, a subtropical moss from the family Pterobryaceae, is native to the western Himalaya. In this study, the complete chloroplast genome of P. orientalis was sequenced using the Illumina NovaSeq 6000 platform, as a resource for future research on the classification and evolution of the Pterobryaceae. The genome was 124,719 bp in length, consisting of a large single-copy (LSC: 87,401 bp), a small single-copy (SSC: 18,530 bp), and two inverted repeat regions (IRs: 18,788 bp). The genome consisted of 126 unique genes, including 82 protein-coding genes, 36 tRNA genes, and eight rRNA genes. The overall GC content of the whole chloroplast genome was 52.09%. Phylogenetic analysis showed that P. orientalis is closely related to the genus Calyptothecium.
