Phylogeography of Chrysanthemum indicum L. (Compositae) in China based on trnL-F sequences

► In this study, we used the trnL-F noncoding sequences of cpDNA to examine the phylogeographical pattern of 27 populations of C. indicum across the southwest to northwest areas in China. ► The main research highlights of this study are: Demonstrated that contiguous range expansion and restricted gene flow/dispersal but with some long distance dispersal seemed to have shaped the present-day distribution of the haplotypes of C. indicum in China.
