Complete chloroplast genome analysis of <i>Hypopterygium flavolimbatum</i> Müll. Hal. (Hypopterygiaceae, Bryophyta)

To address limited genomic resources hindering <i>Hypopterygium</i> phylogenetics/taxonomy, the chloroplast genome of <i>Hypopterygium flavolimbatum</i> Müll. Hal. (Hypopterygiaceae, Bryophyta) was sequenced. The chloroplast genome is 125,283 bp in length, comprising an 86,845 bp large single-copy region, an 18,606 bp small single-copy region, and a pair of 9916 bp inverted repeats. A total of 127 genes were predicted, including 82 protein-coding genes, 36 tRNA genes, and 8 rRNA genes. Phylogenetic analysis indicates that <i>H. flavolimbatum</i> exhibits the closest genetic affinity with a clade containing <i>Myurella julacea</i>, <i>Myuroclada maximowiczii</i>, and <i>Climacium dendroides</i>. This study provides essential sequence data for species identification and phylogenetics.
