The identification of Mycosphaerella graminicola effectors that promote pathogenicity on wheat. Fungal diseases are one of the greatest challenges to sustainable wheat production in the 21st century. Septoria tritici blotch is one such disease as it inflicts millions of tonnes in yield losses per annum. This project will identify the molecular basis of Septoria tritici blotch and assess its potential as an Australian biosecurity threat.
Evolving with sexually transmitted infections. This project aims to understand how sexually transmitted infections (STIs) affect the evolution of host mating systems. STIs threaten the health of most sexually-reproducing organisms. In evolutionary terms, their mode of transmission imposes distinct selection patterns on hosts. This project will use an Australian beetle and its sexually transmitted mite to investigate how STIs lead to evolutionary changes in host mating behaviour and explore the g ....Evolving with sexually transmitted infections. This project aims to understand how sexually transmitted infections (STIs) affect the evolution of host mating systems. STIs threaten the health of most sexually-reproducing organisms. In evolutionary terms, their mode of transmission imposes distinct selection patterns on hosts. This project will use an Australian beetle and its sexually transmitted mite to investigate how STIs lead to evolutionary changes in host mating behaviour and explore the genetic basis for STI resistance. This project is expected to affect the evolution of host mating biology and lead to sex-specific optimal levels of disease resistance, which can influence disease dynamics and host-disease coevolution.Read moreRead less
Does coevolution drive speciation? This project aims to connect micro-evolutionary processes with macro-evolutionary patterns to test the extent to which tightly coupled co-evolutionary interactions between species drive evolutionary diversification. The project will use techniques including the most recent phylogenetic modelling methods, field experiments and molecular genetics. Expected outcomes include advancing understanding of the mechanisms that generate biodiversity and developing new tec ....Does coevolution drive speciation? This project aims to connect micro-evolutionary processes with macro-evolutionary patterns to test the extent to which tightly coupled co-evolutionary interactions between species drive evolutionary diversification. The project will use techniques including the most recent phylogenetic modelling methods, field experiments and molecular genetics. Expected outcomes include advancing understanding of the mechanisms that generate biodiversity and developing new techniques for acquisition of DNA from museum specimens. The project is expected to provide significant benefits, such as insights into the processes that promote new species in nature.Read moreRead less
What drives parasite spread through social networks: lessons from lizards. Australia's biodiversity is continually threatened by new epidemics of local and foreign diseases and parasites. This project will enhance our understanding of how these diseases spread, allowing more effective controls to be developed to protect wildlife species, animal populations and, ultimately, Australian ecosystems.
Parasite transmission through social networks in the pygmy bluetongue lizard. Australia's biodiversity is continually threatened by new epidemics of diseases and parasites, some local, others from overseas. This project will provide information on how they spread so that more effective management of these diseases can be developed to protect wildlife species, animal populations and, ultimately, Australian ecosystems.
Linking individual traits, the gut microbiome and parasite load in wildlife. This project aims to apply principles of community ecology to the gut microbiome of an urban exploiter – the common brushtail possum - to reveal how animal traits influence individual variation in the load of gut parasites that cause disease in both humans and wildlife. By combining assays defining the behavioural and physiological states of individuals with sophisticated analyses of their gut microbiome, our project wi ....Linking individual traits, the gut microbiome and parasite load in wildlife. This project aims to apply principles of community ecology to the gut microbiome of an urban exploiter – the common brushtail possum - to reveal how animal traits influence individual variation in the load of gut parasites that cause disease in both humans and wildlife. By combining assays defining the behavioural and physiological states of individuals with sophisticated analyses of their gut microbiome, our project will provide a new, yet crucial, perspective on how and why diseases spread. Our discoveries will help understand and manage the burden of infectious diseases from parasites in and beyond our cities and across the human-wildlife interface; essential for improving human and wildlife health in an increasingly urbanised Australia.Read moreRead less
Factors causing wheat stripe rust epidemics. This project aims to tackle wheat stripe rust, one of the most important fungal diseases of wheat in Australia, causing losses of up to $125 million a year. This project expects to gain insights into the fungal evolution and the molecular mechanism that causes hyper-virulent pathogen isolates. The expected outcome is to identify and characterise multiple genetic factors in the pathogen that contribute to wheat stripe rust epidemics in Australia. This ....Factors causing wheat stripe rust epidemics.

This project expects to gain insights into the fungal evolution and the molecular mechanism that causes hyper-virulent pathogen isolates. The expected outcome is to identify and characterise multiple genetic factors in the pathogen that contribute to wheat stripe rust epidemics in Australia. This project will contribute to improved disease management strategies to contain wheat stripe rust, resulting in higher wheat yields, reduced application of fungicides and increased revenue for Australian wheat farmers.Read moreRead less

Summary
Uncovering how rust fungi cause devastating plant diseases. This project aims to generate a new understanding of how rust fungi infect plant cells using single-cell sequencing technologies and data-driven investigations. This project expects to discover conserved rust infection strategies and the first characterisations of mechanisms that transfer virulence proteins from the fungus to the plant. Innovations and new knowledge from this project will be of high-impact and of benefit to the Australi ....Uncovering how rust fungi cause devastating plant diseases. This project aims to generate a new understanding of how rust fungi infect plant cells using single-cell sequencing technologies and data-driven investigations. This project expects to discover conserved rust infection strategies and the first characterisations of mechanisms that transfer virulence proteins from the fungus to the plant. Innovations and new knowledge from this project will be of high-impact and of benefit to the Australian and international community through knowledge discovery about conserved rust infection mechanisms. This project expects to deliver strategies for effective rust disease management that will in the future lessen the impact of rust diseases on agriculture and natural ecosystems in Australia.Read moreRead less
Cuckoo - host coevolution: a model system for investigating the impact of climate change on interspecific interactions and biodiversity. Climate change is causing alterations to the timing of breeding and migration in Australian birds, resulting in mismatches in timing between closely interacting species. This project will assess the impact of climate change on interactions between parasitic cuckoos, hosts and prey and formulate predictions about the long-term viability of these species.
The role of auxin in root organ specification - from symbiont to parasite. Sustainable agriculture in a changing climate depends on strategies to maximise crop performance and to minimise crop losses due to parasites. This project aims to identify genes and molecular mechanisms that symbiotic and parasitic microbes, which affect major crop plants, use to alter plant growth in a beneficial or detrimental way.
