Figure 5.

Response of latex- and laticifer-defective E. lathyris plants to inoculation with the fungal pathogen B. cinerea.

(A) Disease symptoms in wild-type plants and lack of them in the pil1 mutant at 4 dpi. Scale bars represent 1 cm.

(B) Phenotype of leaves from inoculated wild-type, pil1, pil6, and pil10 plants at 4 dpi. Scale bars represent 1 cm.

(C) Percentage of leaf area affected by necrotic lesions at 4 dpi. Error bars represent mean ± SE (one-way ANOVA, p < 0.0001).

(D) Germinated conidia in wild-type surface leaves and absence of germination in pil1 mutants, as revealed by trypan blue staining at 4 dpi.

(E) Severe cellular lesions in wild-type plants, minor lesions in the pil10 mutant, and absence of lesions in pil1 and pil6 mutants, as revealed by trypan blue staining at 4 dpi.
