Abstract:
Corydalis repens Mandl & Muhldorf is an early spring-blooming species within the genus Corydalis. In this study, we present the complete chloroplast genome of C. repens for the first time. The assembled genome is 188,101 base pairs (bp) long and is organized into a typical quadripartite structure consisting of a large single-copy (LSC) region of 89,844 bp, a small single-copy (SSC) region of 757 bp, and two inverted repeat (IR) regions totaling 48,750 bp. The overall GC content is 40.2%. The plastome encodes 141 genes, including 94 protein-coding genes, 38 transfer RNA genes, and eight ribosomal RNA genes, along with a single pseudogene (clpP). Phylogenetic reconstruction indicates that C. repens is nested within section Corydalis and shows the closest affinity to C. maculata. These findings provide an important genetic resource for future studies on the evolutionary history and conservation of the genus Corydalis.
