A great diversity in mechanisms of resistance - Non-host resistance - Genetics of non-host resistance
5 important questions on A great diversity in mechanisms of resistance - Non-host resistance - Genetics of non-host resistance
What relates to a trait that defines species non-host resistance?
- It is rarely possible to elucidate this trait through classical genetic research.
Which lettuce species can be crossed for genetic analysis?
- L. saligna is considered as far as we know and caused by Bremia lactucae.
What did the study of L. sativa and L. saligna hybrid cross result in?
- At least 15 minor genes were involved.
- Higher grades + faster learning
- Never study anything twice
- 100% sure, 100% understanding
What sort of insights can be gained from genetic studies on host-pathogen combinations?
- Studies include host-pathogen combinations in which susceptibility is extremely rare or low-level.
What application of mutagenesis in genetic research has been indicated?
- EPF genes have been identified that are required for non-host resistance.
The question on the page originate from the summary of the following study material:
- A unique study and practice tool
- Never study anything twice again
- Get the grades you hope for
- 100% sure, 100% understanding
