Phylogenetic network reconstruction of 71 Ginkgo accessions. a TCS network based on complete plastomes. 17 haplotypes were clustered into eight haplotype group (A-H), different colors represent populations of origin. Six sample names denote the samples used in the gymnosperm-wide dataset. Size of haplotype pie charts is proportional to the number of individual sequences assigned to the respective haplotype. b Geographic distribution of the eight haplotype groups. Map was created with packages ‘maps’ [62], ‘mapdata’ [63] and ‘mapplots’ [64] in R version 3.2.3 [65] using the ‘worldHires’ map. Detailed geographic coordinates are provided with Additional file 1
