spotted gum tree

• Spotted gum tree / Basket grass
• Phytophthora dieback (fungal)
• Pattern recognition receptors (PRRs): These detect fungal molecules and activate immune pathways to stop infection early.
• • In basket grass, hydrogen peroxide is produced at infection sites, which kills fungal cells and signals for further defence responses.
• • In spotted gum, infected cells and surrounding healthy cells die to prevent the spread of the fungus. This is an effective immune strategy against pathogens that spread between living cells.
