A multitude of attackers lies in wait
13 important questions on A multitude of attackers lies in wait
What might other reactions to plant tissue attacks be called?
What is not always a reliable indicator of the amount of pathogen present in a plant?
- Symptoms may not directly equate to pathogen levels.
How can many pathogens and parasites be identified in a plant?
- Identification is possible through signs and direct visibility.
- Higher grades + faster learning
- Never study anything twice
- 100% sure, 100% understanding
What is the consequence of an infection in plants according to the text?
- Pathogen quantity may not be proportional to symptom severity.
How can the local presence of a leaf blotch fungus be deduced?
- Pathogen quantity is indirect by lesion size and number.
Why do the authors prefer to avoid the term disease for plant infections?
- Infections can affect singular parts or the entire physiology.
How is the term 'pest' defined in the context of plants?
- White fly on tomato is provided as an example of a pest.
How are pathogens classified?
- Diversity includes fungi like powdery mildew, rust, and loose smuts.
What is the role of haustoria in pathogenic fungi?
- They may reprogram the plant's responses.
What are necrotrophs, and how do they interact with plant tissue?
- They kill plant tissue to extract nutrients.
- Often produce toxins and thrive on dead plant tissue.
- Can be grown on artificial media.
What characterizes hemibiotrophs, and what can happen to plant tissue during their infection?
- They can cause plant tissue death soon after infection.
- Some are cultivable on media (e.g., P. infestans), others not (e.g., Bremia lactucae).
What are opportunistic pathogens, and what are some examples?
- Examples include Pythium and Rhizoctonia causing seedling damping-off.
What are vascular wilts, and what are a couple of examples of fungi causing them?
- Fungi like Fusarium oxysporum and Verticillium dahliae cause these wilts.
