Life hanging on a thread; disrupting the structure and function of lepidopteran silking behaviour. The production and use of silk by many invertebrates is vital for their survival. We develop a means of visualising and understanding the role of silking behaviour as a survival mechanism for Helicoverpa larvae (a key world-wide pest) with a view to disrupting silking. This novel project allows us to understand not just where larvae go but what they do along the way. The project outcomes will have ....Life hanging on a thread; disrupting the structure and function of lepidopteran silking behaviour.

This novel project allows us to understand not just where larvae go but what they do along the way. The project outcomes will have wide application to the study and control of lepidopteran pests in natural and agricultural ecosystems and is of interest to applied and fundamental projects associated with insect pest control, behaviour and ecology.Read moreRead less
A novel role for phytochrome in dormancy release inhibition. Seed dormancy contributes to the persistence of weeds in agriculture by enabling seeds to remain viable in the soil for many years, and is a major reason why annual ryegrass (Lolium rigidum) has become the most economically damaging weed in Australian agriculture. Recently we discovered a new way to control dormancy release and germination in these seeds. This project to identify the changes occurring within the seeds during dormancy r ....A novel role for phytochrome in dormancy release inhibition. Seed dormancy contributes to the persistence of weeds in agriculture by enabling seeds to remain viable in the soil for many years, and is a major reason why annual ryegrass (Lolium rigidum) has become the most economically damaging weed in Australian agriculture. Recently we discovered a new way to control dormancy release and germination in these seeds. This project to identify the changes occurring within the seeds during dormancy release will underpin our efforts to manipulate emergence timing in order to improve the efficacy of current weed control practices and contribute to sustainable farming systems.Read moreRead less

Summary
The Insect-Plant Chemical Ecology Network (IPCEN). We bring together plant molecular biology, entomology and analytical chemistry to transform three leading fields of Australian research into an advanced science with far reaching capabilities in innovative research and applied outcomes. Expertise studying the biochemical pathways that produce specific plant compounds and expertise in insect recognition and response to these chemicals will be brought together. This will lead to new research outco ....The Insect-Plant Chemical Ecology Network (IPCEN). We bring together plant molecular biology, entomology and analytical chemistry to transform three leading fields of Australian research into an advanced science with far reaching capabilities in innovative research and applied outcomes. Expertise studying the biochemical pathways that produce specific plant compounds and expertise in insect recognition and response to these chemicals will be brought together. This will lead to new research outcomes and solutions to problems in agriculture, horticulture, forestry and protection of Australia's native flora. Researchers are struggling to create these links, constrained by disciplinary boundaries and geographical isolation. Key industries and researchers already support this proposal.Read moreRead less
Building better Brassicas: Understanding disease resistance mechanisms across the Brassicaceae. Brassica species are important crops producing cooking oil, vegetables and biofuel, grown in diverse environments with a high economic and export value. Blackleg disease, caused by the fungus Leptospheria maculans, is the most important disease of brassica crops world-wide. The newly available brassica genome sequence provides the resources to study the co-evolution of this plant and pathogen. This pr ....Building better Brassicas: Understanding disease resistance mechanisms across the Brassicaceae. Brassica species are important crops producing cooking oil, vegetables and biofuel, grown in diverse environments with a high economic and export value. Blackleg disease, caused by the fungus Leptospheria maculans, is the most important disease of brassica crops world-wide. The newly available brassica genome sequence provides the resources to study the co-evolution of this plant and pathogen. This project will characterise the evolution and conservation of resistance genes in wild and cultivated brassicas, using next-generation sequencing technology, to assess their potential for crop improvement. An understanding of the evolution of genes responsible for resistance will lead to improved plant protection strategies for brassica crops.Read moreRead less

Summary
Assessing pollination services of honey bees in native ecosystems and threats posed by parasites. The European honeybee is our most abundant pollinator but we know little about its role in native Australian ecosystems or how its many diseases may affect its ability to pollinate. This project will determine whether honeybees are important pollinators of native plants and how a common parasite affects their pollination ability.
The ecology of parasite transmission in fauna translocations. Parasitic diseases pose a threat to the conservation management of Australia's biodiversity. This project will improve our understanding of the impact and transmission of parasites in fauna translocations, contributing to the conservation management of Australian ecosystems by government and private agencies.
Rhinovirus impairs physiological and immunological lung development and causes exacerbation of allergic airways disease. Rhinovirus (RV) infections account for around 90 per cent of asthma exacerbations, yet the mechanisms behind this are unknown. This project will use mouse models to study the effects of early life RV infection and allergic sensitisation on respiratory and immunological development, with the expectation that early life RV infection disrupts anitgen presenting cell function.
Improving Treatment Strategies For Chronic Alphaviral Arthritic Diseases

Summary
Chikungunya virus and Ross River virus cause epidemics of acute and chronic arthritic disease in humans, which is often poorly managed with current treatments. This grant seeks to understand the mechanisms that give rise to disease in order to identify improved treatment strategies. Both the persistence of viral replication in joint tissues and unnecessary inflammatory responses appear to be important factors driving chronic disease.
Navigating an uncertain antimicrobial future: a sociological study. This project aims to develop a unique understanding of what governs antibiotic use in the health sector and how it can be governed more effectively. The project will critically assess the implementation of governance, and how regulatory and legislative environments may resonate or contrast with the demands of practice. This will support the development of strategies to improve antibiotic use and reduce resistance.
Improving Health Outcomes In The Tropical North: A Multidisciplinary Collaboration

Funding Amount
$5,997,916.00
Summary
Improving Health Outcomes in the Tropical North will strengthen partnerships with research institutions in the NT, Qld, WA, NSW, Vic and SA, by undertaking a research agenda that will help close the gap in Indigenous health disadvantage, protect the north from emerging infectious threats and engage regional neighbours. We will establish a northern Australian network that incorporates Indigenous engagement, mentoring and knowledge translation, and facilitates collaboration with southern partners.
