Mongolian endemic Potentilla
In this study, we report the complete chloroplast genome sequences of five endemic Potentilla species from Mongolia for the first time. These species are narrowly distributed in western Mongolia and are traditionally used in local medicine. We comprehensively characterize their chloroplast genome features and conduct comparative analyses with closely related species from clade Argentea to clarify the phylogenetic position and local evolutionary patterns of these endemic taxa. Our results identify divergence hotspots in SSC intergenic regions and lineage-specific signals of selection in ycf1 and rpoC1, providing insights into plastome evolution and potential adaptive differentiation among endemic taxa.
