From: Genetic barriers more than environmental associations explain Serratia marcescens population structure

Fig. 5

a Stacked bar charts showing the percentage of genes with Horizontal Gene Transfer (HGT) events inferred for each cluster from 1062 core genes. Intra indicates genes with HGT events which happened within strains of the same cluster. Donor indicates genes with HGT events departing from the cluster to other clusters. Recipient indicates genes with HGT events departing from other clusters. b Heatmap showing the χ 2 residuals of S. marcescens clusters pairs on the basis of the total number of HGT events inferred between them. Statistically significant associations are marked with an asterisk (*). c Heatmap showing the χ 2 residuals of S. marcescens clusters pairs on the basis of R-M systems compatibility. Statistically significant associations are marked with an asterisk (*). d Heatmap showing the χ 2 residuals of R-M system type distribution in the S. marcescens. Statistically significant associations are marked with an asterisk (*).
