Remodelling encapsulin nanocages to help enhance plant carbon fixation. Nature has evolved mechanisms in microbial systems to improve photosynthetic efficiency by saturating the enzyme Rubisco with carbon dioxide. These carbon concentrating mechanisms are genetically complex, precluding successful introduction into crops. Our simpler approach is to use encapsulins, a new source of robust bacterial pore-containing nanocages made from a single gene.

These carbon concentrating mechanisms are genetically complex, precluding successful introduction into crops. Our simpler approach is to use encapsulins, a new source of robust bacterial pore-containing nanocages made from a single gene. This project will optimise the development of synthetic encapsulin-Rubisco carbon-fixing nanoreactors and transform them into leaf chloroplasts to test their impact on plant photosynthesis and growth. Our genetically simpler solution will aid ongoing global efforts to deliver overdue step change improvements in agricultural productivity.Read moreRead less

This proposal aims to establish an Australian Advanced Metabolic Signal Discovery and Imaging platform. The platform consists of an ultra-high resolution gas chromatography mass spectrometer and an imaging mass spectrometry upgrade for a second existing high resolution mass spectrometer. The facility will break barriers currently limiting discovery and localisation of metabolic changes during plant and animal development under environmental stress; integral chemical signals exchanged in host-microbe interactions; and volatile signatures linked to ecosystem health and developmental anomalies in animals. Results will inform innovative strategies to enhance biological adaptation, climate resilience and plant, animal, and ecosystem health.Read moreRead less
Control of developmental switches by importin 5. Aims: This project will study a key molecular switch called IPO5, a protein that is required for cells and organs to form and function normally, and it will reveal how it works.
Significance: These experiments will provide the first complete description of how this molecular switch controls the behaviour of a cell across its lifespan. IPO5 is highly conserved, so these studies will be relevant to a wide range of animals.
Expected Outcomes: This k ....Control of developmental switches by importin 5. Aims: This project will study a key molecular switch called IPO5, a protein that is required for cells and organs to form and function normally, and it will reveal how it works.
Significance: These experiments will provide the first complete description of how this molecular switch controls the behaviour of a cell across its lifespan. IPO5 is highly conserved, so these studies will be relevant to a wide range of animals.
Expected Outcomes: This knowledge will reveal how IPO5 controls formation of sperm by revealing what other proteins it binds to and how this affects cell signaling and responses to the environment.
Benefits: This will provide information about potential interventions to control fertility or to repair abnormal cells.

Flipping the mattress: infinite polyurethane recycling by synthetic biology. Australia is covered in billions of tonnes of plastic and yet <10% is recycled today. Polyurethane (PU) is ubiquitous in our everyday lives, from lacquer coatings to elastane clothing to durable foam padding in car seats, cushions and mattresses. Currently, there are few avenues for PU recycling and much ends up in landfill e.g., a single mattress produces 15-20kg of PU foam waste. Luckily, biodegradation of PU can occu ....Flipping the mattress: infinite polyurethane recycling by synthetic biology. Australia is covered in billions of tonnes of plastic and yet <10% is recycled today. Polyurethane (PU) is ubiquitous in our everyday lives, from lacquer coatings to elastane clothing to durable foam padding in car seats, cushions and mattresses. Currently, there are few avenues for PU recycling and much ends up in landfill e.g., a single mattress produces 15-20kg of PU foam waste. Luckily, biodegradation of PU can occur naturally via various microbial means and from insects, like Galleria mellonella larvae. The overall aim of this research project is to understand plastic biodegradation and translate nature’s solutions into flexible and efficient synthetic enzyme technologies that can sustainably recycle commonly used PU foams.

Can altered sugar sensing improve crop productivity? This project aims at genetically manipulating sugar sensing pathways in the model C4 grass Setaria viridis, and at replacing sugar sensors in the model C3 crop Oryza sativa (rice) with those from S. viridis. This project expects to elucidate the impact of altered sugar perception on crop photosynthesis and yield. Expected outcomes includes advancing a novel “pull” approach to improve yield in C3 crops by using C4-like sugar sensors to reduce f ....Can altered sugar sensing improve crop productivity? This project aims at genetically manipulating sugar sensing pathways in the model C4 grass Setaria viridis, and at replacing sugar sensors in the model C3 crop Oryza sativa (rice) with those from S. viridis. This project expects to elucidate the impact of altered sugar perception on crop photosynthesis and yield. Expected outcomes includes advancing a novel “pull” approach to improve yield in C3 crops by using C4-like sugar sensors to reduce feedback regulation of photosynthesis which in turn limits productivity. This is in contrast to previous ‘push’ approaches aimed at directly increasing photosynthesis. Hence, this project provides significant benefits by contributing to the next green revolution needed to lift agricultural yields.Read moreRead less
Improving plant reproductive success under heat stress: A sweet approach. This project aims to determine how genetic manipulation of cell wall invertase (CWIN) activity could regulate pollen germination, elongation and fruit set under heat stress using tomato as a model. Plant reproductive processes are highly susceptible to heat stress, which often leads to pollination failure and fruit and seed abortion, hence irreversible yield loss. Research has established that CWIN-mediated sugar metabolis ....Improving plant reproductive success under heat stress: A sweet approach. This project aims to determine how genetic manipulation of cell wall invertase (CWIN) activity could regulate pollen germination, elongation and fruit set under heat stress using tomato as a model. Plant reproductive processes are highly susceptible to heat stress, which often leads to pollination failure and fruit and seed abortion, hence irreversible yield loss. Research has established that CWIN-mediated sugar metabolism and signaling may play crucial roles in pollen growth and fruit set under heat stress. The intended outcome is the generation of critical knowledge that will advance understanding on reproductive development under heat stress, thereby providing significant benefits, such as novel ideas and solutions for improving crop yield.Read moreRead less

The major aim of this project is to determine evolutionary conserved physical principles of mechanotransduction in living cells through structure and function studies of PIEZO mechanoreceptor channels playing a crucial role in senses such as touch and pain in animals and humans.

The major aim of this project is to determine evolutionary conserved physical principles of mechanotransduction in living cells through structure and function studies of PIEZO mechanoreceptor channels playing a crucial role in senses such as touch and pain in animals and humans. Mutations in these channels can cause numerous genetic disorders, including hereditary anaemias and joint contractures. Since they have been shown to respond to mechanical stimuli in the same manner as mechanoreceptor channels of organisms from bacteria to humans the intended outcome of this project is to uncover the unifying principles of mechanotransduction anchored in the laws of physics and chemistry that have guided the force-dependent design of all life forms.Read moreRead less

This project aims to characterise host molecules (in particular lipids) that are crucial for the transition of malaria parasites from one host to another. Malaria parasites encounter different environments upon their transition from human to the mosquito host. This project expects to generate new knowledge on physiological changes that are triggered by particular differences in micronutrient abundance that allow the parasites to survive in the new host. Anticipated outcomes include the identification of new intervention strategies and improved transmission model systems for vector-borne diseases. This gained knowledge could provide benefits to future biomedical applications by informing diagnostics or treatment of lipid associated diseases.Read moreRead less
