Supplementary Figure 6: Legionella effector gain and loss dynamics.
From: Genomic analysis of 38 Legionella species identifies large and diverse effector repertoires
The number of effector gain events and the number of effector loss events were computed on the basis of phyletic patterns of effector presence/absence using a maximum-likelihood algorithm62. Pie size is proportional to the rate of events (number of events normalized to branch length). Each pie presents the ratio between gain (green) and loss (red) of effectors. The results suggest that the L. pneumophila clade (species marked in dark red) is much more prone to gain and loss of effectors than the L. micdadei clade (marked in dark green). The numbers on the right refer to the cluster of effector repertoires in Figure 4.
