# The complete chloroplast genome of Corydalis wilsonii N. E. Brown 1903 and its phylogenetic analysis

## TL;DR

This study sequenced the complete chloroplast genome of Corydalis wilsonii and used it to clarify its evolutionary relationships with other species in the genus.

## Contribution

The paper provides the first complete chloroplast genome for C. wilsonii and a robust phylogenetic framework for the genus Corydalis.

## Key findings

- The chloroplast genome of C. wilsonii is 191,388 bp with a quadripartite structure and 140 functional genes.
- C. wilsonii is phylogenetically grouped with C. saxicola, C. tomentella, and C. fangshanensis in sect. Thalictrifoliae with 100% bootstrap support.
- The study enhances genomic resources for Corydalis and aids in resolving taxonomic uncertainties.

## Abstract

Species within Corydalis are valued for medicinal and ornamental uses but taxonomic uncertainties persist due to limited genomic data. Here, we present the complete chloroplast genome of C. wilsonii, with a quadripartite structure of 191,388 bp and 140 functional genes. Phylogenetic analysis robustly resolves C. wilsonii within a monophyletic clade alongside C. saxicola, C. tomentella, and C. fangshanensis, all nested within sect. Thalictrifoliae (bootstrap support = 100%). This study expands the chloroplast genomic resources for Corydalis and establishes a taxonomic framework to refine species identification and resolve evolutionary relationships within this ecologically and economically vital genus.
