## Contribution

The study presents the first complete chloroplast genome sequence of Blechnopsis orientalis and its phylogenetic analysis.

## Key findings

- The chloroplast genome is 155,211 bp long with specific regions and a GC content of 41.3%.
- A total of 131 genes were annotated, including 88 protein-coding genes.
- Phylogenetic analysis shows B. orientalis is closely related to Oceaniopteris gibba.

## Abstract

Blechnopsis orientalis (Linnaeus) C. Presl (1753) is a fern used both as food and medicine. It is found primarily in southern China and Southeast Asia, thriving in warm, humid shrublands or sparse forest. The total length of the chloroplast genome is 155,211 bp, including a large single-copy region (LSC, 81,877 bp), a small single-copy region (SSC, 21,500 bp), and two inverted repeat regions (IRs, 25,917 bp). The GC content is 41.3%. A total of 131 genes were annotated, including 88 protein-coding genes, eight rRNA genes, and 35 tRNA genes. The phylogenetic analysis using the maximum-likelihood method showed that B. orientalis and Oceaniopteris gibba were closely related. This study provides genomic resources for phylogenetic genetics and resource exploitation of B. orientalis.
