Summary
Towards understanding the molecular details of canola-infection by Fusarium. This project aims at improving our understanding of how canola plants are infected by the pathogenic fungus Fusarium oxysporum. Canola is the primary oilseed crop, and the overall third most important crop in Australia, accounting for a 3 billion AUS$ industry. Fusarium is a relatively new fungal disease to Australian canola, but projected to become a serious threat in the future.

This project aims at improving our understanding of how canola plants are infected by the pathogenic fungus Fusarium oxysporum. Canola is the primary oilseed crop, and the overall third most important crop in Australia, accounting for a 3 billion AUS$ industry. Fusarium is a relatively new fungal disease to Australian canola, but projected to become a serious threat in the future. The project will provide insights into the earliest stages of plant-infection by the fungus on a cellular level, using molecular biology, genetics and microscopic tools. Expected outcomes of this research include the identification of key components to improve plant defense against Fusarium, and the development of strategies to improve the plant's resilience.Read moreRead less
Discovery of novel circular proteins in bacteria, plants and animals: applications in drug design and crop protection. The overall goal is to use innovative methods in chemistry, biochemistry and molecular biology to determine the structures and functions of several families of circular proteins that have exciting pharmaceutical and agricultural applications. These molecules differ from conventional proteins in that they have no ends: their termini are seamlessly joined, thereby making them exce ....Discovery of novel circular proteins in bacteria, plants and animals: applications in drug design and crop protection. The overall goal is to use innovative methods in chemistry, biochemistry and molecular biology to determine the structures and functions of several families of circular proteins that have exciting pharmaceutical and agricultural applications. These molecules differ from conventional proteins in that they have no ends: their termini are seamlessly joined, thereby making them exceptionally stable and resistant to enzyme digestion. The big question is ?How and why does Nature produce circular proteins?" Increasing our knowledge of why circular proteins have evolved will facilitate their applications in drug design and in the development of novel insecticides.Read moreRead less
Australia's native sorghums: a model for testing plant adaptation theories. This proposal tests an emerging theory that allocation of resources by plants to growth or defence are interrelated, not alternatives as currently assumed. Like many crops, sorghum produces toxic cyanide, especially during droughts but its wild relatives make much less. This project aims to discover why cyanide is so common in domesticated plants and why levels increase with stress. This has important implications for de ....Australia's native sorghums: a model for testing plant adaptation theories. This proposal tests an emerging theory that allocation of resources by plants to growth or defence are interrelated, not alternatives as currently assumed. Like many crops, sorghum produces toxic cyanide, especially during droughts but its wild relatives make much less. This project aims to discover why cyanide is so common in domesticated plants and why levels increase with stress. This has important implications for developing crops that are high yielding and also climate resilient. Expected outcomes include full genome sequences for all of Australia’s unique native sorghums, confirmation of new theories on the interrelationships between defence and growth and identification of new traits vital for developing the crops of the future.

The roles viruses play in the decline of terrestrial orchids in Australia’s hotspot of global biodiversity. Plant viruses play both positive and negative roles in native plant health and population viability. This study will use deep sequencing and plant physiology approaches to elucidate how threatened terrestrial orchids respond to infection by exotic and indigenous viruses, allowing more informed management of critically-important ecosystems.
Species traits, substrates and stormwater grates: improving the health of urban trees by using polluted stormwater as a resource. This project uses plant traits to select existing and novel tree species for glasshouse studies to quantify the uptake of stormwater and polluting nutrients as well as drought tolerance in stormwater street tree systems. In collaboration with water industry and tree nursery industry partners and a syndicate of local councils, the project aims to install passive stormw ....Species traits, substrates and stormwater grates: improving the health of urban trees by using polluted stormwater as a resource. This project uses plant traits to select existing and novel tree species for glasshouse studies to quantify the uptake of stormwater and polluting nutrients as well as drought tolerance in stormwater street tree systems. In collaboration with water industry and tree nursery industry partners and a syndicate of local councils, the project aims to install passive stormwater street tree systems into existing suburbs and new greenfield developments in Melbourne. Models will be used to design and predict the performance of these stormwater street tree systems, and the glasshouse/field research outputs are expected to refine the leading industry and government relevant urban catchment model.Read moreRead less
Tree-mediated methane fluxes: A new frontier in the global carbon cycle. Methane is an extremely potent greenhouse gas. Recent evidence suggests that tree-mediated fluxes may be a significant, but overlooked source of methane to the atmosphere. This project aims to quantify the magnitude and drivers of tree-mediated methane fluxes from Australia’s dominant forest types. Innovatively, we will be using a novel combination of empirical field based measurements, gas tracer experiments, microbial ana ....Tree-mediated methane fluxes: A new frontier in the global carbon cycle. Methane is an extremely potent greenhouse gas. Recent evidence suggests that tree-mediated fluxes may be a significant, but overlooked source of methane to the atmosphere. This project aims to quantify the magnitude and drivers of tree-mediated methane fluxes from Australia’s dominant forest types. Innovatively, we will be using a novel combination of empirical field based measurements, gas tracer experiments, microbial analysis and modelling methods. Expected outcomes are a mechanistic understanding of tree-mediated methane fluxes, helping to constrain regional, national and global methane budgets. The results of this study will help inform publicly funded greenhouse gas abatement strategies, ensuring a maximal return on investment.Read moreRead less
Advanced cryobanking for recalcitrant-seeded Australian rainforest plants. This project aims to develop an interdisciplinary research alliance to enhance the efficiency of ecological restoration for recalcitrant Australian rainforest plant species. The project expects to provide fundamental knowledge to target two major impediments to cryostorage of recalcitrant-seeded native species: desiccation sensitivity with relatively large size, and active metabolism and precocious germination. These attr ....Advanced cryobanking for recalcitrant-seeded Australian rainforest plants. This project aims to develop an interdisciplinary research alliance to enhance the efficiency of ecological restoration for recalcitrant Australian rainforest plant species. The project expects to provide fundamental knowledge to target two major impediments to cryostorage of recalcitrant-seeded native species: desiccation sensitivity with relatively large size, and active metabolism and precocious germination. These attributes severely limit the time available for effective use of collected germplasm for long-term storage. A combination of biochemical, biophysical and molecular simulation approaches will be used to optimise cryopreservation of a wide range of endangered Australian rainforest species. This should provide significant benefits such as enabling conservation agencies to greatly enhance their ability to preserve the unique Australian rainforest flora, particularly given current threats due to habitat loss and global warming.Read moreRead less

Reducing environmental footprint by improving phosphorous use efficiency. While modern agriculture relies heavily on the use of phosphorous fertilizers, most of them are not used by plants and lost in runoff, resulting in a massive environmental damage through contamination of waterways (termed eutrophication). This project takes advantage of an untapped resource - a unique collection of Tibetan wild barley genotypes, to reveal key traits that confer superior phosphorus use efficiency in wild ba ....Reducing environmental footprint by improving phosphorous use efficiency. While modern agriculture relies heavily on the use of phosphorous fertilizers, most of them are not used by plants and lost in runoff, resulting in a massive environmental damage through contamination of waterways (termed eutrophication). This project takes advantage of an untapped resource - a unique collection of Tibetan wild barley genotypes, to reveal key traits that confer superior phosphorus use efficiency in wild barley and identify appropriate candidate genes and their position on chromosomes for further incorporating these traits into commercial barley cultivars. This will reduce the environmental footprint of modern agricultural practices on terrestrial and aquatic ecosystems without compromising food security.Read moreRead less
