The complete plastome of <i>Campsis radicans</i> (L.) Bureau 1864 and its phylogenetic analysis

<i>Campsis radicans</i> (L.) Bureau 1864, a species of Bignoniaceae, has a widespread paleotropical distribution and is utilized for horticultural and traditional Chinese medicinal purposes. Despite the plant’s significance, its genetic diversity must be better understood. In this study, we have successfully assembled and characterized the complete plastome of <i>C. radicans</i>, marking a significant advancement toward comprehending its genetic composition. The plastome is 153,630 bp long and harbors 130 genes, including 86 protein-coding genes, 36 tRNA genes, and eight rRNA genes. Our phylogenomic analysis of the representative species of Bignoniaceae indicated that <i>C. radicans</i> formed a monophyletic sister clade of <i>Campsis</i> with <i>C. grandiflora</i>. These findings are crucial for conserving and utilizing this important plant species. They also highlight the potential for future research into the evolution and preservation of <i>C</i>. <i>radicans</i>, which could be advantageous in pharmaceutical applications.
