Question
Chapter 38.4, Problem 1C
Summary Introduction
To determine: Whether the observed necrotic lesions on the plant leaves are more likely due to a hypersensitive response or to systemic acquired resistance (SAR).
Introduction: Instead of an immune system, the plants have some defense mechanisms that are used to defend themselves from the attack of the pathogenic and herbivorous enemies. It consists of an efficient innate immune system and acquired resistance that help it to fight against local infections.

In 1985 a Paterson, N.J., Fire Department ambulance responded to a call reporting two people with severe itching, which they attributed to "voodoo beans" found in their beds. Soon after arriving the ambulance medical technicians developed the same symptoms. All four of the individuals went to the emergency room where they were found to have rashes on various parts of the body in addition to their itch. The admitting nurse, who put her arm around one patient, also developed a rash and itch on her arm. A policeman who went to the apartment the following day and a trash collector at the building also developed itching and received emergency room treatment. In all cases, symptoms disappeared in 1-2 hours. An industrial hygienist went to the site in complete protective gear to look for possible chemical contamination. Visual inspection and screens for ionized organic vapors were negative, but he retrieved a bean pod. The botanical specimen was sent to Rutgers University, where the plant was…
