The first complete chloroplast genome sequence of an early spring flowering plant, <i>Corydalis repens</i>

<i>Corydalis repens</i> Mandl & Muhldorf is an early spring-blooming species within the genus <i>Corydalis</i>. In this study, we present the complete chloroplast genome of <i>C. repens</i> 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 (<i>clpP</i>). Phylogenetic reconstruction indicates that <i>C. repens</i> is nested within section <i>Corydalis</i> and shows the closest affinity to <i>C. maculata</i>. These findings provide an important genetic resource for future studies on the evolutionary history and conservation of the genus <i>Corydalis</i>.
