All plants have resistance to some pathogens under cutin conditions. Different plants defend themselves against pathogens in different ways. The defense mechanism of plants against pathogens falls into two categories: 1. Morphological or Structural Defense Mechanism 2. Biochemical Defense Mechanism. 1. Morphological or Structural Defense Mechanism: The first line of defense against pathogens is the surface barriers which a pathogen [...]
In this article we will discuss about how do plants protect and defend themselves from pathogens and diseases. Introduction to Pathogens: Once a pathogen has arrived in the vicinity of a potential host plant or, as may happen in the case of soil-borne pathogens, a plant root has arrived in the vicinity of a pathogen, subsequent events depend on the [...]
In this article we will discuss about the structural and biochemical defense mechanisms in plants I. Structural Defense: In plants some structures are already present to defend the attack while in others, the structures to defend the host develops after the infection. In this way, structural defense can be characterised as (A) Preexisting defense structures and (B) Defense structures developed [...]
