# Phylogenomic insights from the complete chloroplast genome of Berchemiella wilsonii var. pubipetiolata H. Qian (Rhamnaceae) from Zhejiang

## TL;DR

This paper reports the first complete chloroplast genome of a rare plant species from China, offering insights into its evolution and conservation.

## Contribution

The study provides the first assembled chloroplast genome for Berchemiella wilsonii var. pubipetiolata, supporting phylogenomic and conservation research.

## Key findings

- The chloroplast genome is 160,317 bp long with a typical quadripartite structure and 37.20% GC content.
- Phylogenetic analysis confirms its close relationship to B. wilsonii.
- The genome includes 131 genes, such as 84 mRNA, 37 tRNA, and 8 rRNA genes.

## Abstract

Berchemiella wilsonii var. pubipetiolata H. Qian, a member of the Rhamnaceae family, is endemic to mountainous regions in two eastern Chinese provinces. Here, we present the first assembly of its chloroplast (cp) genome, which exhibits a typical quadripartite structure, spans 160,317 bp long and has a 37.20% GC content. Genome annotation identified 131 genes, including 84 messenger RNA (mRNA) genes, 37 transfer RNA (tRNA) genes, and eight ribosomal RNA genes. Phylogenetic analysis confirms its close relation to B. wilsonii, thereby providing valuable genomic resources for conservation efforts and evolutionary studies of East Asian Berchemiella species.
