Additional file 11: of Genomic analysis of the Phalaenopsis pathogen Dickeya sp. PA1, representing the emerging species Dickeya fangzhongdai

Genetic differentiation and gene flow analysis of different D. fangzhongdai subpopulations. The Chinese subpopulation of D. fangzhongdai included PA1 and DSM101947. The European subpopulation included B16, S1 and MK7. The Malaysian subpopulation included ND14b, M005 and M074. Nucleotide diversity (Pi) indicates the average number of nucleotide variations per site. Ks*, Z, and Snn were all calculated for statistical testing of differentiation among different subpopulations. FST was measured to determine the level of gene flow between subpopulations; an absolute value of FST < 0.33 suggests frequent gene flow. (XLSX 11 kb)
