Characterization of the complete chloroplast genome of <i>Aesculus pavia</i>

<i>Aesculus pavia</i> L., a member of the genus <i>Aesculus</i> in the family Sapindaceae, holds significant value as both a medicinal and ornamental plant. In this study, we assembled and annotated the complete chloroplast genome of <i>A. pavia</i> and conducted the phylogenetic analysis among the genus <i>Aesculus</i>. The complete chloroplast genome of <i>A. pavia</i> is 156,394 bp in length, with a GC content of 37.90%. It exhibits a typical quadripartite structure, consisting of a large single-copy (LSC) region (85,927 bp), a small single-copy (SSC) region (18,751 bp), and a pair of inverted repeats (IRs) regions (25,858 bp). A total of 133 genes were annotated, including 88 protein-coding genes (PCG), 37 tRNA genes, and 8 rRNA genes. Phylogenetic analyses revealed that <i>A. pavia</i> is clustered with <i>A. turbinata</i> and <i>A. hippocastanum</i>, suggesting a close relationship between <i>A. pavia</i> and the two species. This study provides a new plastome sequence for evolutionary and phylogenetic studies of the genus <i>Aesculus</i>.
