PCA relating virulence factors of plant-associated P. aeruginosa strains and their pathogenicity against C. elegans. A PCA biplot showing the position of each strain along with the orthogonal positions of the observed variables. The percentage variance explained by each principal component (Dim1 and Dim2) is given in parentheses in axes. B The percent contribution of each principal component to the cumulative variability in PCA. C The percent contribution of each variable on the axis identified by the principal component analysis. The red dotted line indicates significant loading values (> 0.70). D – death; P – paralysis; E – eggs at 24, 48, and 72 h incubation. ATCC10145, ATCC9027, and PAO1 – clinical strains; PPA01 to PPA18 – plant-associated strains; OP50—E. coli (OP50) standard nematode-feeding strain
