A student tests two plant varieties for disease after fungal exposure. Variety A shows very rapid callose deposition around plasmodesmata but no systemic acquired resistance; variety B shows strong SAR. Which would you expect?
How does leaf abscission (dropping an infected leaf) help the plant?
Which practice is an agricultural measure that helps reduce spread of plant pathogens between fields?
Which signalling molecule is commonly associated with systemic acquired resistance (SAR) in plants after local infection?
Some plants recruit ants by providing nectar to protect them from herbivores. This is an example of:
What is the primary advantage of induced (triggered) defenses over constitutive (always-present) defenses?
Which of the following is a physical barrier plants use to reduce pathogen entry?
A farmer adopts integrated pest management (IPM). Which element of IPM is directly linked to enhancing plant biological defences?
What is the main role of stomatal closure during pathogen attack or drought?
A leaf infected by a bacterium produces PR (pathogenesis-related) proteins that degrade bacterial cell walls. This is an example of which defence type?
How can farmers use knowledge of plant innate defences to reduce pesticide use?
