Research interests
Professor Park is particularly interested in the way in which fungal rust pathogens evolve and acquire virulence for resistance genes in their hosts. He has conducted Australia-wide race analyses for the rust pathogens that cause stem rust in wheat, leaf rust in wheat, leaf rust in barley, and crown rust in oats, since 1988. This work has involved analysing more than 10,000 rust samples from farmers’ fields, led to the identification of more than 160 new cereal rust pathotypes, and has clearly demonstrated the increasing frequency of exotic rust incursions into Australia. His research group has developed and applied DNA-based markers to understand how rust pathogen populations have evolved in Australia over the past 100 years, and are now applying whole genome sequencing to delve further.
Robert is also interested in the genetics of resistance to these pathogens in their respective hosts, and his group works very closely with most wheat, barley and oat breeders in Australia to provide support in rust resistance breeding. He has strong linkages with rust researchers throughout Australia via his position as Director of the Australian Cereal Rust Control Program, which is funded by the Grains Research and Development Corporation. He has developed strong research programs on the genetics rust durable rust resistance in barley and oat. His barley genetics work was the first to map minor adult plant resistance to leaf rust in barley, and led to the designation of three important durable and additive minor genes for leaf rust resistance. Robert is also actively involved in international rust research, notably via participation in the global effort to tackle a new race of stem rust, known as Ug99, which emerged in eastern Africa in 1999 and has since spread to Yemen, Iran and South Africa. He is currently leader of an ACIAR funded project that partners with Ethiopia, India, Nepal, and Pakistan to mitigate the effects of stripe rust in wheat production in South Asia and East Africa.
