Question
Chapter 37, Problem 8TYK
Summary Introduction
Introduction:
A defense mechanism is presented by plants when they come in contact with a pathogen. This defense mechanism is triggered when the infection-causing pathogen or a substance produced by the pathogen binds with a specific region of the plant. This binding triggers the mechanism that results in actively fighting against the pathogen.
