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

Fraxinus chinensis subsp. rhynchophylla 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 F. chinensis subsp. Rhynchophylla, 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 Fraxinus species, such as Fraxinus sieboldiana and Fraxinus hupehensis, with strong support values. These findings provide a valuable resource for further evolutionary studies, molecular identification, and medicinal applications of F. chinensis subsp. rhynchophylla.
