Sequencing and analysis of the complete chloroplast genome of the traditional medicinal plant <i>Fraxinus chinensis</i> subsp. <i>rhynchophylla</i> (Oleaceae)

<i>Fraxinus chinensis</i> subsp.<i> rhynchophylla</i> is a traditional medicinal plant. Its chloroplast genome was sequenced, assembled, and analyzed in this study. The results showed that the complete chloroplast genome of<i> F. chinensis</i> subsp.<i> Rhynchophylla,</i> 155,784 bp in length, contains 133 annotated genes, including 88 protein-coding genes (PCGs), 8 rRNA genes, and 37 tRNA genes. Phylogenetic analysis revealed that this subspecies clusters with 14 other <i>Fraxinus</i> species, such as<i> Fraxinus sieboldiana</i> and<i> Fraxinus hupehensis</i>, with strong support values. These findings provide a valuable resource for further evolutionary studies, molecular identification, and medicinal applications of<i> F. chinensis</i> subsp.<i> rhynchophylla.</i>
