ARC Centre of Excellence in Plant Energy Biology. We propose a novel approach to improve sustainable yield by optimising the overall efficiency of energy capture, conversion and use by plants. Efficiency gains in metabolism, transport, and development will be more effective than optimising single nutrient inputs or product outputs. Improving multiple parameters simultaneously is a necessary solution to the increasing demand for more crop yield from finite land, water, and nutrient resources.

We propose a novel approach to improve sustainable yield by optimising the overall efficiency of energy capture, conversion and use by plants. Efficiency gains in metabolism, transport, and development will be more effective than optimising single nutrient inputs or product outputs. Improving multiple parameters simultaneously is a necessary solution to the increasing demand for more crop yield from finite land, water, and nutrient resources. Unpredictable environmental challenges adversely affect plant growth and further perturb plant energy balance, limiting yield. The epigenetic controls, gene variants and signals discovered will provide a new basis for sustainable productivity of crops and will future-proof plants in changing climates.Read moreRead less
In touch with the environment: dissecting early tactile responses in plants. This project aims to identify the regulatory mechanisms that control touch-responses in plants. Although plants cannot relocate in the face of danger, they are able to sense mechanical manipulations from the environment. These could be caused by pathogens, herbivores, rain or even wind. This touch-responsiveness of plants is essential for pathogen resistance and for triggering architectural changes to overcome obstacles ....In touch with the environment: dissecting early tactile responses in plants. This project aims to identify the regulatory mechanisms that control touch-responses in plants. Although plants cannot relocate in the face of danger, they are able to sense mechanical manipulations from the environment. These could be caused by pathogens, herbivores, rain or even wind. This touch-responsiveness of plants is essential for pathogen resistance and for triggering architectural changes to overcome obstacles and prevent mechanical damage. Using a comprehensive tool set of genetics, genomics and proteomics, this project aims to identify the upstream regulators that control touch responses. Furthermore, it is expected to expand our understanding of the physiological impacts of touch-responses on growth and stress tolerance.Read moreRead less
Understanding the biological functions of the karrikin-responsive signaling system of plants in growth, development and responses to the environment. A new signalling system in plants, related to that of strigolactone hormones but evolutionarily more ancient and functionally distinct, has been discovered. It is defined by the Karrkin-Insensitive-2 (KAI2) protein discovered by its ability to confer responsiveness to karrikins from bushfires. The KAI2 system influences seed germination, and develo ....Understanding the biological functions of the karrikin-responsive signaling system of plants in growth, development and responses to the environment. A new signalling system in plants, related to that of strigolactone hormones but evolutionarily more ancient and functionally distinct, has been discovered. It is defined by the Karrkin-Insensitive-2 (KAI2) protein discovered by its ability to confer responsiveness to karrikins from bushfires. The KAI2 system influences seed germination, and development of seedlings, leaves and potentially roots. This project will use KAI2 mutants and transgenic plants to define the biological functions of KAI2 signalling, and its interactions with other signalling systems. New genes central to KAI2 signalling and responses will be identified for functional analysis. The research will reveal the significance of this new signalling system in plant biology.

Deciphering the Thermal Acclimation of Mitochondrial Respiration. Plants acclimate to the extremes of temperature following a pre-exposure to a sub-lethal increase/decrease in temperature. Recent research has revealed that proteins of oxidative phosphorylation and the tricarboxylic acid (TCA) cycle are dynamic and change their abundance in response to temperature change. Harnessing a cutting edge protein mass spectrometry approach, this project seeks to better understand how mitochondrial respir ....Deciphering the Thermal Acclimation of Mitochondrial Respiration. Plants acclimate to the extremes of temperature following a pre-exposure to a sub-lethal increase/decrease in temperature. Recent research has revealed that proteins of oxidative phosphorylation and the tricarboxylic acid (TCA) cycle are dynamic and change their abundance in response to temperature change. Harnessing a cutting edge protein mass spectrometry approach, this project seeks to better understand how mitochondrial respiration and hence adenosine triphosphate (ATP) production is maintained during temperature change. Uniquely this project will examine this in both the model plant Arabidopsis and wheat and combine both tissue, environment-induced and genotype variation to reveal a new understanding of the thermal acclimation of this major mitochondrial process.Read moreRead less
Genome editing to improve the dietary quality of potato. The project aims to develop non-genetically modified (non-GM) potato varieties with lower glycaemic index (GI) but good agronomic and culinary traits. Potato is the world's fourth-most important food. It is integral to the western diet and consumption is rising rapidly in Asia. However, the starch in cooked potato is readily digestible causing a rapid elevation of blood sugar levels on eating (i.e. it has a high GI). Long-term consumption ....Genome editing to improve the dietary quality of potato. The project aims to develop non-genetically modified (non-GM) potato varieties with lower glycaemic index (GI) but good agronomic and culinary traits. Potato is the world's fourth-most important food. It is integral to the western diet and consumption is rising rapidly in Asia. However, the starch in cooked potato is readily digestible causing a rapid elevation of blood sugar levels on eating (i.e. it has a high GI). Long-term consumption of meals with high GI is associated with increased risk of obesity, type-2 diabetes and cardiovascular disease. This project aims to use new genome editing methods to silence key genes that influence starch composition and thus develop non-GM potato varieties with lower GI to reduce these risks.Read moreRead less

This research hub aims to provide Australian growers and industrial stakeholders with improved plant materials to maximise production, environmental sustainability and profitability. In particular, the research aims to improve the nitrogen delivery capacity of legumes and their resilience to abiotic stress, which will be an important consideration as our climate changes. Grain legumes are often grown in rotation with cereal crops for their high nutritional seed value and their unique ability to develop a self-sufficient nitrogen-fixing symbiosis with soil bacteria. Maintaining legume productivity against the challenges of climate change and the need for increased food production is important to the future of Australian agriculture.Read moreRead less

This process takes place in chloroplasts, subcellular structures that derived from photosynthetic bacteria a billion years ago. Chloroplasts have their own DNA, containing genes encoding the most important photosynthetic proteins. This project aims to provide the world’s best resources for the study of chloroplast genes. In the process, we will discover how these important genes are regulated to provide photosynthetic proteins in the right amounts, in the right cells, at the right time. The knowledge and resources gained will facilitate improvement of photosynthetic function in future agricultural crops.Read moreRead less

This project plans to measure the rate at which proteins degrade inside plants by using stable isotopes of nitrogen and mass spectrometry analysis of isolated protein samples from different plant mutant lines. This will allow new insights into the in vivo role of specific proteases which are involved in regulating energy generating pathways in plant organelles and that are needed for light tolerance, adaptation to day length, growth and normal leaf development. The new information will aid us to develop approaches to alter quality control of the plant proteome as a tool for engineering energy processes in plants.Read moreRead less
How do sunflowers make protein drugs in their seeds? We recently discovered in sunflower the origin of a small protein ring that chemists have used for a decade to base designed drugs upon. This project aims to know how sunflowers make it so we may manipulate other plants to manufacture ring-based drugs.
