Abstract Background The genus Sanicula L. is a unique perennial herb that holds important medicinal values. Although the previous studies on provided us with good research basis, its taxonomic system and interspecific relationships have not been satisfactorily resolved, especially for those endemic to China. Moreover, evolutionary history of this also remains inadequately understood. plastid genomes possessing highly conserved structure limited rate proved be an effective tool studying plant phylogeny evolution. Results In current study, we newly sequenced assembled fifteen complete plastomes. Combined two previously reported plastomes, performed comprehensively phylogenomics analyses gain novel insights into genus. comparative results indicated seventeen plastomes exhibited high degree conservation similarity in terms their structure, size, GC content, gene order, IR borders, codon bias patterns SSRs profiles. Such as all them displayed typical quadripartite including large single copy region (LSC: 85,074–86,197 bp), small (SSC: 17,047–17,132 bp) separated by pair inverted repeat regions (IRs: 26,176–26,334 bp).

The genus Hydrocotyle Tourn. ex L. is a key group for further study on the evolution of Apiales, comprising around 170 species globally. Previous studies mainly focused separate sections and provided much information about this genus, but its infrageneric relationships are still confusing. In addition, genetic basis adaptive remains poorly understood. To investigate phylogeny we selected ten representative covering two three diversity distribution centers exhibiting rich morphology diversity. Comparative plastome analysis was conducted to clarify structural character plastomes. Positive selection analyses were implemented assess genus. Phylogenetic inferences with protein-coding sequences (CDS) 17 related also performed. Plastomes within generally conservative in structure, gene order, size.
