Figure 3: Extent of effector sharing by the Legionella species studied.
From: Genomic analysis of 38 Legionella species identifies large and diverse effector repertoires
Circles represent sets of effectors (eff.) shared by a different number of Legionella species (sp.). The number of species in which these effectors were found is indicated at the top of each circle, and the number of effectors contained in the set is indicated on the bottom. The innermost circle represents the set of core effectors shared by all Legionella species studied. The outermost circle depicts the 258 species-specific effectors and is divided on the basis of the number of species-specific effectors found in each Legionella species. Notably, only seven effectors are shared by all Legionella species, and most effectors (78.5%) are shared by ten or fewer species (two outermost circles). Lpne, L. pneumophila; Ldra, L. drancourtii; Llng, L. longbeachae; species abbreviations for newly sequenced species appear in Supplementary Table 1.
