Deficiencies in Jasmonate-Mediated Plant Defense Reveal Quantitative Variation in Botrytis cinerea Pathogenesis

Figure 4

Response to B. cinerea infection in jasmonate-insensitive and camalexin-deficient A. thaliana.

Necrotic area and camalexin accumulation induced by B. cinerea isolates BcGrape and Bc83-2 in A. thaliana genotypes WT (wild-type Col-0 produced as seed from heterozygous COI1/coi1), pad3, coi1, and coi1 pad3. Measurements were taken at 72 hours post inoculation. Within each figure, letters above bars indicate statistical significance; bars not sharing letters represent significant mean differences at p<0.05. A) necrotic area (cm2 ± SE) B) camalexin (ng/cm2 leaf area ± SE).
