The complete chloroplast genome of an Arctic lycophyte, Huperzia arctica (Tolm.) Sipliv. 1973 (Lycopodiaceae)

Abstract

AbstractHuperzia arctica (Tolm.) Sipliv. 1973 is a lycophyte species belonging to the Lycopodiaceae family, which is widely distributed in the Arctic region of Svalbard, Norway. To determine its taxonomic position, we sequenced the chloroplast genome of H. arctica. The complete chloroplast genome of H. arctica is 153,956 bp in length with 122 annotated genes, including 87 protein-coding genes, 31 tRNA genes, and 4 rRNA genes. To evaluate its evolutionary position, we performed phylogenetic analysis using 36 conserved orthologous protein-coding gene sequences from the chloroplast genomes of H. arctica and publicly available data from other Lycopodiaceae. H. arctica formed a monophyletic group with four other Huperzia species: H. lucidula, H. serrata, H. crispata, and H. javanica. However, it appeared as a separate species with a highly supported bootstrap value.
