i use eucalyptus calophylla and the pathogen is sm phyto cinnamonWhat r you guys 's example for this dot point: Investigate the response of a named Australian plant to a named pathogen through practical and/or secondary-sourced investigation, for example: fungal pathogens, viral pathogens.
For the fungal pathogen I am doing Wollemi pine but I can't find a lot of information on it, this is all I have for now:
Example: Wollemi pine
Disease: Phytophthora dieback
Causative pathogen: Phytophthora cinnamomi
Symptoms:
The root lesions prevent uptake of water and nutrients from the soil which can cause the plant’s leaves to discolour and wilt. The plant attempts to respond to the pathogen by dropping its leaves to conserve energy to fight the fungus.
- Rot of fine feeder roots
- Root cankers leading to dieback
- Decline in yield
- Collar rot
- Root lesions
- Leaves wilting and discolouration
Is anyone else doing this plant and if you do can you please give some more info on this????
plant response:
- increased lignin production = protect cell wall from pathogenic damage = physical barrier (catalysed by PAL and phenolics and stuff to maintain healthy and thick plant roots)
