Summary Introduction

Introduction:

Pathogens are considered as agents of disease and these are mostly fungi, bacteria, nematodes that live off the plant and damage its tissues. Plants have certain mechanisms that put off or kill attackers. The first line of defense for plants is its impenetrable bark that is composed of bark and waxy cuticle. Both of these barriers protect plants from pathogens.
