Overview

Plant viruses and horticultural crop improvement

Dr Dietzgen is internationally recognised for his work on plant virus characterisation, detection and engineered resistance. Before joining UQ, Dr Dietzgen was a Science Leader in Agri-Science in the Queensland Department of Employment, Economic Development and Innovation. He previously held research positions at the University of Adelaide, University of California, Cornell University and University of Kentucky. Dr Dietzgen’s research interests are in molecular virus-plant-insect interactions, virus biodiversity and evolution, and disease resistance mechanisms. His focus is on the biology of RNA viruses in the family Rhabdoviridae and the molecular protein interactions of plant-adapted rhabdoviruses and tospoviruses. He has published extensively on plant virus characterisation and genetic variability, RNAi- mediated virus resistance and diagnostic technologies with 20 review articles and book chapters and over 65 peer-reviewed publications.

Research Interests

  • Pest and disease management and control
    Study of molecular plant-virus-insect interactions to identify novel targets for plant disease & pest control. Main focus on negative strand RNA virus (rhabdovirus, tospovirus) characterization, biodiversity, taxonomy and interactions with their hosts and insect vectors. Host-delivered RNA silencing for disease resistance against pests and diseases. Application of next generation sequencing technologies for virus characterization and diagnostics.

Qualifications
