Cellular and molecular components of plant defence against pathogens

This project investigated how plants respond to invading pathogens using microscopic, biochemical and genetic approaches. The development of transgenic plants containing the green fluorescent protein cloned from jellyfish enabled a new approach to studying plant defence genes. In particular, the role and involvement of the plant gene PAL1 was analysed.

Defence mechanisms of a resistant monocot model to phytophthora cinnamomi

The plant pathogen Phytophthora cinnamomi causes devastating disease in natural and agricultural systems worldwide. While some plants can survive, little is known about the underlying mechanisms of resistance. This research used histochemical and genome-wide analysis to identify key cellular and molecular defence mechanisms within the resistant plant Zea mays.

Profiling secondary metabolites of plant roots inoculated with Phytophthora cinnamomi

The soil-borne pathogen, Phytophthora cinnamomi, continues to cause severe dieback in Australian native forest species and is of great international significance due to its global distribution. This research established a protocol to successfully identify phyto-chemicals associated with the defense response of plants challenged by the disease caused by Phytophthora cinnamomi.
