Ann-Maree obtained a BSc (Hons), was awarded a University Medal, and then a PhD in Plant Sciences from the ANU. Her PhD research was completed at CSIRO on the interaction between flax and the rust pathogenic fungus Melampsora lini, this work was recognised by receiving the ‘CSIRO Plant Industry Chief’s Award for Individual Excellence in Research’. She then accepted a postdoctoral position at the University of California, Berkeley, where she continued to investigate molecular plant-pathogen interactions. In 2010, she was awarded an Australian Postdoctoral Fellowship from the ARC and returned to the ANU to work on the molecular basis of Fusarium wilt resistance in tomato. She continues to work on fungal-plant interactions using the flax-flax rust pathosystem.


Research interests

My research focuses on trying to understand how phytopathogenic fungi manipulate their host to establish an infection through the use of effector proteins, and how plant resistance proteins function to trigger defence responses to prevent disease. Currently I am investigating these questions using two different fungal-plant interactions, Fusarium oxysporum f. sp. lycopersici which causes wilt disease of tomato and Melampsora lini which causes rust disease of flax.

Some of my specific research goals include:

  • Understand the molecular events required for activation and signalling of the atypical resistance protein I-3 from tomato.
  • Understand how the Avr1 effector from the Fusarium wilt pathogen is able to suppress I‑3 mediated resistance in tomato.
  • Determine the mechanism by which effectors secreted from the flax rust pathogen are able to cross the host plasma membrane during infection.
  • Reveal what roles the identified flax rust effectors play during infection.
