Current research interests

  • A major focus of my research at The James Hutton Institute is the discovery and functional characterisation of P. infestans genes required for pathogenicity and avirulence on the host plant potato, through an integrated genomics approach. Genes found to be crucial for the successful infection of potato are clearly potential targets for future late blight, and broader oomycete, control strategies.
  • Active areas of research in the Phytophthora genomics lab include: effector/avirulence gene discovery and characterisation, screening for candidate pathogenicity factors using transient gene silencing (RNA interference), characterisation of RXLR-EER-mediated effector protein translocation into host plant cells, and cell biology of P. infestans/plant interactions using pathogen::fluorescent proteins fusions.

Past research

  • My PhD research characterised the genetics of avirulence in the soybean root rot pathogen Phytophthora sojae, the genome of which has now been sequenced.
  • I joined SCRI as a postdoc in 1999 on a project based around the creation of genomics capabilities for P. infestans at SCRI, including constructing a large insert bacterial chromosome library, physical mapping of selected genomic regions, and targeted gene discovery using cDNA-AFLP and suppression subtractive hybridisation.
  • In 2002 I was awarded the first SEERAD Senior Research Fellowship to work on an integrated genomics strategy for P. infestans, and identify genes involved in the interaction with its host potato.
  • Although much previous research has been heavily biased towards genetic markers, genomics studies, and gene discovery, recent research has been driven by the need to determine the function of novel oomycete genes in the P. infestans / potato interaction.

The James Hutton Research Institute is the result of the merger in April 2011 of MLURI and SCRI. This merger formed a new powerhouse for research into food, land use, and climate change.
