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

ABSTRACT: Campsis radicans (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 C. radicans, 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 C. radicans formed a monophyletic sister clade of Campsis with C. grandiflora. 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 C. radicans, which could be advantageous in pharmaceutical applications.

Project description:BackgroundAlpinia species are widely used as medicinal herbs. To understand the taxonomic classification and plastome evolution of the medicinal Alpinia species and correctly identify medicinal products derived from Alpinia species, we systematically analyzed the plastome sequences from five Alpinia species. Four of the Alpinia species: Alpinia galanga (L.) Willd., Alpinia hainanensis K.Schum., Alpinia officinarum Hance, and Alpinia oxyphylla Miq., are listed in the Chinese pharmacopeia. The other one, Alpinia nigra (Gaertn.) Burtt, is well known for its medicinal values.ResultsThe four Alpinia species: A. galanga, A. nigra, A. officinarum, and A. oxyphylla, were sequenced using the Next-generation sequencing technology. The plastomes were assembled using Novoplasty and annotated using CPGAVAS2. The sizes of the four plastomes range from 160,590 bp for A. galanga to 164,294 bp for A. nigra, and display a conserved quadripartite structure. Each of the plastomes encodes a total of 111 unique genes, including 79 protein-coding, 28 tRNA, and four rRNA genes. In addition, 293-296 SSRs were detected in the four plastomes, of which the majority are mononucleotides Adenine/Thymine and are found in the noncoding regions. The long repeat analysis shows all types of repeats are contained in the plastomes, of which palindromic repeats occur most frequently. The comparative genomic analyses revealed that the pair of the inverted repeats were less divergent than the single-copy region. Analysis of sequence divergence on protein-coding genes showed that two genes (accD and ycf1) had undergone positive selection. Phylogenetic analysis based on coding sequence of 77 shared plastome genes resolves the molecular phylogeny of 20 species from Zingiberaceae. In particular, molecular phylogeny of four sequenced Alpinia species (A. galanga, A. nigra, A. officinarum, and A. oxyphylla) based on the plastome and nuclear sequences showed congruency. Furthermore, a comparison of the four newly sequenced Alpinia plastomes and one previously reported Alpinia plastomes (accession number: NC_048461) reveals 59 highly divergent intergenic spacer regions. We developed and validated two molecular markers Alpp and Alpr, based on two regions: petN-psbM and psaJ-rpl33, respectively. The discrimination success rate was 100 % in validation experiments.ConclusionsThe results from this study will be invaluable for ensuring the effective and safe uses of Alpinia medicinal products and for the exploration of novel Alpinia species to improve human health.
