Implication

Randomized trial assesses species relationships in Gentiana flexicaulis complex, indicating taxonomic clarity for conservation efforts.

Key Points

This research aims to clarify the phylogenetic relationships and taxonomic status of the Gentiana flexicaulis complex endemic to the Qinghai-Tibet Plateau.
Utilized a large set of single-copy orthologous genes and complete chloroplast genome sequences combined with morphological data.
Examined geographic distribution to identify sub-lineages and taxonomic positions of related species.
Performed phylogenetic analysis using both nuclear and chloroplast data.
Clarified the delimitation of G. flexicaulis and identified three distinct sub-lineages.
Proposed a new subspecies, G. flexicaulis subsp. brevicorolla, with distinct morphological traits and phylogenetic independence.
Demonstrated that incomplete lineage sorting and hybridization are primarily observed within species rather than among them.
