Lorena is a plant pathologist in the epidemiology group within the Cell and Molecular Sciences department. Her research focuses on the foliar microbiome of agricultural crops or their wild progenitors and how phytopathogenesis impacts community structure. In particular, she is interested in investigating the potential to exploit the foliar and endophytic microbiome for tailored disease control of plant pathogenic bacteria and fungi.

Current Research Interests and Impact

Native microbial strains are better adapted to offering plants protection from local biotic stresses, and profiling these communities offers an approach for biocontrol research in any crop pathosystem. Using a crop agnostic approach, cataloguing the native plant microbiome has the potential to provide low-risk biological control alternatives and a foundation for commercial application.

Foliar Microbiome Research

    • Phyllosphere (epiphyte & endophtye) characterisation of healthy/diseased signatures
    • Assessing function of hub taxa for crop protection
    • Biocontrol of plant pathogenic bacteria and fungi
    • Work with industry towards creation of safe biologicals 

 

 

 

 

 

 

 

Secondary Metabolite Research

  • Discovery of SM involvement in phytopathogenesis
  • Identification of cross-kingdom SM communication
  • Validating function of SM gene clusters
  • Improve crop protection through plant resistance inducers
