A great diversity in mechanisms of resistance - Non-host resistance - formae speciales
8 important questions on A great diversity in mechanisms of resistance - Non-host resistance - formae speciales
What are formae speciales and how do they relate to pathogen strains?
- They are also known as forma specialis in singular form.
What superficially appear to be generalists but may consist of different specialist strains?
- An example is the powdery mildew fungus Blumeria graminis.
How does Blumeria graminis behave with different host species?
- It shows host-specific pathogenicity, affecting wheat but not barley or oats.
- Higher grades + faster learning
