Slide 1:Harmful organism Recognition by resistance protein Signal to cell nucleus Genetic material Defense Response Defense protein Outside plant cell Inside plant cell Diagram of a plant disease resistance protein in action. A portion of the protein (MAROON) lies outside the cell and specifically recognises the harmful organism. The remaining portion of the protein (RED) resides inside the cell and communicates a signal to the plant’s genetic material, which in turn stimulates a defense response against the invading organism.
