FIGURE 5.

Effects of bacterial strains on sporangia germination. (A) Observed germination phenotypes included regular germination (g), sporangia-like swellings (sl) and tip-swelling (ts). (B) Mean sporangia germ tube length was estimated. Different letters indicate significant differences between strains (Kruskal Wallis’ test, p < 0.05; see section Materials and Methods). (C) PCA of sporangia germination as a function of germ tube phenotype. Germ tube length (l) was added as a supplementary variable (dashed arrow).
