Unravelling the secrets of the rhizosphere of crops. Phosphate is one of the most important limiting nutrients for crop growth and production. Plant acquisition of soil phosphate largely depends on root proliferation to accelerate soil exploration, and on phosphate bioavailability mediated by root exudates and rhizosphere microorganisms. Central to this is the need for a better understanding of the complex biogeochemical interfaces in the rhizosphere. This project explores recently developed non ....Unravelling the secrets of the rhizosphere of crops. Phosphate is one of the most important limiting nutrients for crop growth and production. Plant acquisition of soil phosphate largely depends on root proliferation to accelerate soil exploration, and on phosphate bioavailability mediated by root exudates and rhizosphere microorganisms. Central to this is the need for a better understanding of the complex biogeochemical interfaces in the rhizosphere. This project explores recently developed non-destructive imaging, isotope, and metabolism techniques to generate a systematic research tool in tracking rhizosphere interactions and imaging phosphate dynamics from macroscale to nanoscale levels. This study will provide new opportunities to improve crop nutrient use efficiency and crop production.Read moreRead less

An expected outcome of this project is support development of genetically stable bacterial inoculants for use in agriculture. Inoculation of legumes with nitrogen-fixing symbiotic bacteria is a cheap and environmentally-friendly alternative to chemical fertilisers and contributes $3-4 billion per annum to Australian economy.Read moreRead less
Dissecting novel roles of succinate dehydrogenase in stomatal aperture and root elongation in plants. Succinate dehydrogenase (complex II) is part of the respiration processes in plants and new evidence shows that reactive oxygen species generated by it can influence plant development and stress tolerance. However, there are still many unanswered questions about the composition and function of this enzyme and its dual roles in plants. This project will study this protein complex in the model p ....Dissecting novel roles of succinate dehydrogenase in stomatal aperture and root elongation in plants.

Phosphorus-efficient Australian plants: applications for crop improvement. This project aims to investigate ways to improve the phosphorus (P) efficiency of selected crops (Lupinus) in Australia. The phosphorus impoverished soils in Australia has allowed the evolution of plants that are highly efficient at acquiring and using phosphorus.

This project aims to investigate ways to improve the phosphorus (P) efficiency of selected crops (Lupinus) in Australia. The phosphorus impoverished soils in Australia has allowed the evolution of plants that are highly efficient at acquiring and using phosphorus. Increasing understanding of highly-efficient phosphorus use mechanisms at the physiological, biochemical, anatomical and molecular biological levels will provide knowledge of traits to guide breeding efforts to develop more phosphorus efficient crops that can perform well in P-limited environments; an outstanding strategy to balance the phosphorus demand for increasing global food production with gradually decreasing non-renewable phosphorus reserves. An expected outcome of this project is to develop crops better able to use scarce phosphorus.Read moreRead less

In addition to transformational photocatalytic technology to utilise Australian raw resources, this project expects to generate new knowledge in the areas of photochemistry, materials science and nanotechnology. These should not only expand the applications of 2D nanomaterials to a new domain of photocatalysts, but also may eventually lead to new industry advances in 2D nanomaterials for a ‘hydrogen economy’.

This project aims to delineate a pathway involved in regulating skeletal muscle mass, and examine whether disrupting mitochondrial phospholipid synthesis affects mitochondrial structure and function, causing muscle wasting. Defining a new atrophy pathway will advance understanding of the mechanisms that control muscle mass. This project could have important economic and quality of life benefits, especially for agriculture, where achieving optimal muscle mass ensures international competitiveness, productivity and economic growth, and successful ageing, where maintaining muscle mass is essential.Read moreRead less
Ecosystem response to climate and anthropogenic disturbances: implications for greenhouse gas emissions and nutrient cycling. Humanity is challenged with climate change, greenhouse gas emissions, declining fertiliser reserves and a need to feed the world's growing population. This project will result in greater understanding of how ecosystems can respond to these challenges and provide a framework to help Australia manage its agricultural and natural reserves.
Discovery of signalling molecules that mediate communication in the environment. This project aims to further our understanding of chemical compounds that mediate communication in the environment.

This project seeks to discover new ways to improve crop productivity by investigating a recently identified chemical signalling pathway in plants that affects seed germination, seedling growth, leaf development and water use. The aims are to identify unknown signalling compounds that work through this pathway, to discover the molecular regulators of the pathway, and to examine how it operates in different plant species. The project also plans to exploit this pathway to find inhibitors of premature seed germination that afflict crops such as wheat and barley. The intended outcomes are a better understanding of how plants grow and new strategies for boosting plant performance in the field. Specific potential applications include reducing plant water use, regulating seed germination, and encouraging early seedling establishment. Read moreRead less
Advancing our understanding of plant responses to low phosphorus availability beyond the transcriptome. Phosphorus is essential for plant growth. Plants have evolved mechanisms to cope with the poor availability of phosphorus in many soils. This project will improve Australia's knowledge of how plants alter the expression of genes and proteins to activate their mechanisms for coping with poor phosphorus availability in some soils.
