Comparative chloroplast genome analysis of Ardisia (Myrsinoideae, Primulaceae) in China and implications for phylogenetic relationships and adaptive evolution.

ABSTRACT:

Background

Numerous species of Ardisia are widely used for their medicinal and ornamental values in China. However, accurately identifying Ardisia species at the molecular level remains a challenge due to the morphological similarities among different species, the complexity of interspecific variation, and the limited availability of genetic markers. In this study, we reported 20 chloroplast genomes of Ardisia species from China and combined them with 8 previously published chloroplast genomes to conduct a comprehensive analysis for phylogenetic relationships and adaptive evolution.

Results

For the 28 Ardisia species analyzed in this study, the size of the chloroplast genomes ranged from 155,088 bp to 156,999 bp, and all exhibited a typical tetrad structure with conserved ge
