The complete chloroplast genome and phylogenetic status of <i>carpesium nepalense</i> less. 1831 (asteraceae)

The complete chloroplast genome of <i>Carpesium nepalense</i> (Asteraceae), an important medicinal herb, was characterized. It exhibits a typical quadripartite structure with inverted repeats (24,947 bp), a large single-copy region (82,870 bp), and a small single-copy region (18,473 bp), with 37.7% GC content. The genome contains 133 genes, including 88 protein-coding, 37 tRNA, and 8 rRNA genes. Phylogenetic analysis confirms <i>Carpesium</i> as monophyletic, with <i>C. nepalense</i> genetically closest to <i>C. cernuum, C. faberi, C. lipskyi</i>, and <i>C. longifolium</i>. This work enriches the molecular database of <i>Carpesium</i> and provides new genomic resources for the development and utilization of medicinal herbs..
