PR1 Expression across Arabidopsis Genotypes.

Rank plot showing the relationship of PR1 expression across three host genotypes (x axis) in control and in response to 30 diverse B. cinerea isolates (right). The isolates shown on the plot were chosen to provide an image of the major patterns found in the full collection of 96 isolates. The isolate names are shown in the same order as the lines for the npr1-1 mutant. The three Arabidopsis genotypes are wild-type Col-0 (red dot), JA-insensitive mutant coi1-1 (blue triangle), and SA mutant npr1-1 (brown diamond). The model-corrected means for transcript of PR1 are utilized for this plot. The transcript expression levels of PR1 across three Arabidopsis genotypes in control or induced by the same isolate are represented with colored connecting lines. Blue line indicates the expression levels of PR1 in the control treated samples. Purple lines indicate isolates where the expression levels of PR1 are higher in coi1-1 and npr1-1 than in Col-0. Black lines indicate isolates where the PR1 expression levels are higher in coi1-1 than in Col-0 but lower in npr1-1. Orange lines indicate isolates where the highest PR1 expression levels are in Col-0. The green line indicates an isolate with slightly higher PR1 expression levels in npr1-1 and slightly lower in coi1-1.
