1. Two negative regulatory pathways (orange and cyan) and one positive regulatory pathway (green). Dotted lines indicate minor pathways.
2. The NPR1-dependent negative regulation of SA biosynthesis has been removed from the model (blue).
3. As the signal transduction pathway connecting the avr/R gene interaction with PCD is not established, it has been lumped into one term called "Triggering factor(s)"
