Chloroplast Genome Diversity and Molecular Evolution in Hypericaceae: New Insights from Three <i>Hypericum</i> Species.

ABSTRACT: The Hypericaceae family, comprising nine genera and over seven hundred species, includes Hypericum plants traditionally used for medicinal purposes. In this study, we performed high-throughput sequencing on three Hypericum species: Hypericum acmosepalum, Hypericum addingtonii, and Hypericum beanii, and conducted comparative genomic analyses with related species. The chloroplast genome sizes were 152,654 bp, 122,570 bp, and 137,652 bp, respectively, with an average GC content of 37.9%. All genomes showed a quadripartite structure, with significant variations in IR regions (3231-26,846 bp). The total number of genes ranged from 91 to 129. SSRs were predominantly located in the LSC region, with mononucleotide repeats being dominant. Comparative analysis iden
