Caption
Jasmonate activity is included systemically by pathogens. Here plants are infected by bacteria carrying different avirulence genes (avrRpm1 at bottom right, avrRps4 at bottom left, avrRpt2 at top right). A systemic immune response triggered by each Avr gene starts at different times as measured by jasmonate signalling (via JISS1:LUC). The JISS1:LUC activity lights up starting at the infiltrated leaf (*) and then spreading through the plant to adjacent and distant leaves, the earliest of which happens in under 4 hours (Bottom right). A bacteria without an avirulence gene (top left) acts as a control as the plant shows no immune response across the 24 hour period.
