The vcf file was produced by STACKS software, and various derivative SNP files were used for specific analyses (e.g., PCA, STRUCTURE, and demographic history analysis).
Intra-generic diversity was estimated between closely-related species for Dioscorea and Arecaceae or within species (Digitaria excilis and Pennisetum glaucum). Inter-generic diversity was estimated be
We analyzed genetic variation of nuclear genes in T. distichum by using tergeted amplicon sequencing (TAS). A total of 96 individuals were used for analyses. The sequencing was performed by FLX 454 sy
