Comparative Chloroplast Genome and Phylogenetic Analyses of <i>Anna</i> and <i>Lysionotus</i> (Gesneriaceae) Along the Sino-Vietnamese Border.

ABSTRACT: Sympatric species share identical geographical spaces, climatic conditions and survival pressures. Comparative chloroplast genomes among Anna and Lysionotus sympatric species enable exploration of genome-wide evolutionary dynamics of sympatric species. In this study, we assembled and annotated 10 complete chloroplast genomes, representing sympatric species distributed along the Sino-Vietnamese border. We conducted a comparison of chloroplast genomes, characterized their adaptive evolution and used multiple methods to clarify their phylogenetic relationships. Key findings included the following: 1. The number of CDs, rRNA and tRNA varied among different species, whereas they were relatively conserved between the two genera; 2. psaB-psaA, trnL-UAG and ndhD-psaC
