Summary Introduction

To determine:

The reason that human beings and plants have the same components mediating the identical response to the same bacterial protein.

Introduction:

A plant cannot run away from stressful conditions. Therefore, plants have defences against the stressors (imposed by pathogens and non-living environment conditions). For example, wounding of a leaf triggers the production of ABA (abscisic acid), hydrogen peroxide, ethylene, and jasmonic acid. Jasmonic acid increases transcription of genes whose products include several volatile chemicals that are released by the plants. These volatile compounds are known as secondary metabolites.
