Yeast is a model organism and industrial food, fuel, and chemical producer. This project expects to increase our basic understanding of yeast genomes, and develop new tools for engineering whole genomes. Expected outcomes of this project include the engineering and characterisation of the world's first minimal yeast genome, and the development of novel industrial yeast strains. This will provide significant benefits for both fundamental genetics and biochemistry research, and the industrial use of yeast for bio-manufacturing of sustainable foods, fuels, and chemicals.Read moreRead less

Future applications will include generating mutations in cells and model organisms for basic research and creating genetically enhanced agricultural animals or plants.Read moreRead less
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.

IDENTIFYING CONTROL ELEMENTS IN CHLOROPLAST GENE EXPRESSION. Energy from sunlight is captured by photosynthesis in plants, providing the basis for the terrestrial food chain. 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.

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
Microbial junk food: developing synthetic platforms for plastic degradation. This project aims to establish the genetic basis of polyethelene biodegradation (PED) by microbes from the gut microbiome of plastic-eating caterpillars.

This project aims to establish the genetic basis of polyethelene biodegradation (PED) by microbes from the gut microbiome of plastic-eating caterpillars. It will transform the active microbial PED genes into carefully designed synthetic microbes for efficient, safe and large-scale PED. The project will combine innovative functional microbial genetic tools and synthetic biology techniques with solid biochemistry and bioinformatics to produce translatable synthetic platforms containing key genes optimised for efficient PE waste removal. The outcomes will have the potential to transform the relative ineffective and expensive current methods for PE disposal into flexible, cost-effective and sustainable solutions applicable to multiple sectors.Read moreRead less
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. This project will optimise the development of sy ....Remodelling encapsulin nanocages to help enhance plant carbon fixation.

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
Mastering pyrimidine editing in RNA. Many plants and animals can alter their genetic information via RNA (ribonucleic acid) editing, a process that is often essential for the growth and development of the organism. This ability provides accurate control over gene expression and has great potential as a biotechnological tool in agriculture and medicine. RNA editing could be used to switch genes on or off in biotechnological production systems with an unprecedented degree of precision, or to corre ....Mastering pyrimidine editing in RNA. Many plants and animals can alter their genetic information via RNA (ribonucleic acid) editing, a process that is often essential for the growth and development of the organism. This ability provides accurate control over gene expression and has great potential as a biotechnological tool in agriculture and medicine. RNA editing could be used to switch genes on or off in biotechnological production systems with an unprecedented degree of precision, or to correct genetic diseases. This project aims to understand two RNA editing pathways in plants, one of which is found nowhere else and likely to involve a novel enzymatic mechanism. We will use the understanding gained to develop novel RNA processing tools usable in any living organism.Read moreRead less

Cells depend on proteins linking together to build cellular structure, but how weak interactions build stable structure is a mystery. New evidence suggests proteins come together and then change state, employing liquid-like behaviour that builds vital nanoscale structure, such as nuclear bodies called paraspeckles. This project will unlock the secrets of this mysterious behavior of proteins, using paraspeckles as a model.
