GenBank files of three Gentiana section Chondrophyllae species

Gentiana section Chondrophyllae sensu lato encompasses more than 180 species and occupies more a half of species in the genus. In this study, we collected samples across the range of three species (Gentiana aristata, G. crassuloides and G. haynaldii) in section Chondrophyllae s.l., and recovered the intra-species variation by comparing with closely related taxon. Using 25 newly sequenced plastid genomes together with previously published data, we compared structural differences, quantified the variations in plastome size, and measured nucleotide diversity in various regions. Our results recovered that species of G. section Chondrophyllae s.l. has high intraspecific plastome variation, and provided insights into the radiation in this speciose lineage.
