Fig. 2From: A genome-wide scan for genes under balancing selection in the plant pathogen Ralstonia solanacearumAnalysis of genomic region corresponding to the phcBSR operon in strain GMI1000 showing sliding window analyses for two statistics: Tajima’s D (solid line) and Fu & Li’s D* (dotted line). All three genes of the operon comprise about 3.9 Kb of the genome; however, the gene (RSc2734) physically preceding this operon is also shown for comparison purposes. Windows are 200 bp and asterisks indicate the windows with extreme values of respective statistics. Arrows represent gene arrangement in the genome of strain GMI1000Back to article page
