Pathogen Dynamics

Key Goal: Improve understanding of Austropuccinia psidii reproduction in New Zealand

This research aim focusses on understanding the behaviour of A.psidii in its early invasion stages – a globally unique opportunity.

We will utilise the latest genetic tools to monitor how the pathogen evolves as it spreads across study sites.

This fungus can reproduce and spread both clonally and via sexual reproduction. Understanding sexual reproduction in myrtle rust is important because it could be a way in which the pathogen widens its host range and starts to infect new plant species.

Sexual reproduction may also facilitate adaption to new climates, so a key goal of this project is to improve understanding of myrtle rust sexual reproduction in New Zealand. Infected plant host symptoms will also be monitored.

We will conduct both greenhouse and field studies.
