The complete chloroplast genomes of Rhamnus arguta Maxim. and R. parvifolia Bunge (Rhamnaceae)

Abstract

Abstract The genus Rhamnus L. (Rhamnaceae) has high medicinal, ecological, and ornamental value, but its infrageneric classification remains unclear. Here, we sequenced, assembled, and annotated the complete chloroplast genomes of Rhamnus arguta and R. parvifolia using Illumina sequencing. Both plastomes exhibit the typical quadripartite structure, with lengths of 160,566 bp and 161,243 bp, containing 128 and 129 genes, respectively. Phylogenetic analyses support the monophyly of Rhamnus and its close relationship with Frangula. This study provides genomic resources for further phylogenetic and comparative studies within Rhamnaceae.
