Sugar transporters in coral symbiosis and origin of parasitism. We aim to identify how symbiotic algae feed sugar to their coral hosts. Corals need this algal sugar to exist, but no one knows how it is transferred, so understanding this crucial mechanism is hugely significant. The first benefit of this research will be a fundamental understanding about how two organisms (algae and coral) cooperate to build habitats like the Great Barrier Reef. We also aim to explore whether coral/algal coopera ....Sugar transporters in coral symbiosis and origin of parasitism. We aim to identify how symbiotic algae feed sugar to their coral hosts. Corals need this algal sugar to exist, but no one knows how it is transferred, so understanding this crucial mechanism is hugely significant. The first benefit of this research will be a fundamental understanding about how two organisms (algae and coral) cooperate to build habitats like the Great Barrier Reef. We also aim to explore whether coral/algal cooperation paved the way for the origin of parasitism. The second key outcome will be to identify the precise molecular mechanism that allowed parasitism to arise. This will benefit us through understanding the origins of important diseases such as human malaria and related infections of livestock and wildlife.

Symbiotic partnership between algae and animals that powers coral reefs. This project aims to unlock the molecular basis of a partnership between a microscopic plant and an animal that powers coral growth. Most corals depend on microscopic algae living inside their bodies to nourish them. Most corals have to recruit new algae each time they reproduce, but only a particular strain of algae is accepted. This project aims to establish how anemones and corals identify and take in the right alga, how ....Symbiotic partnership between algae and animals that powers coral reefs. This project aims to unlock the molecular basis of a partnership between a microscopic plant and an animal that powers coral growth. Most corals depend on microscopic algae living inside their bodies to nourish them. Most corals have to recruit new algae each time they reproduce, but only a particular strain of algae is accepted. This project aims to establish how anemones and corals identify and take in the right alga, how the alga gives them food, and how the animal hosts regulate growth of their algae to optimise food production but avoid being overrun by algae. Understanding the partnership that drives reef growth and survival may better equip us to protect this threatened resource.Read moreRead less
A lipodomic approach to cnidarian-dinoflagellate symbiosis. Fatty Acids are essential for human health and for reef health. This lipodomic study using newly developed techniques, aims to understand the essential and non-essential fatty acid metabolic exchange in the symbiosis that drives coral reef formation and health, and in turn gives reflective insight into our own metabolism.
Sugars in the real world: are cultured cancer cells a good model system for studying protein glycosylation? It is challenging to study errors in metabolism in human beings, so researchers use cells grown in the laboratory to understand disease processes. This project will determine if cultured cells accurately reflect the real changes to cell surface sugars that occur in all cancers, and the effect of these changes on the invasive properties of colon cancer cells.
Future Industries Research - Biotechnology and Nanotechnology: Small talk: Communication networks in microbes. We will use the Australian Proteome Analysis Facility to address the multifaceted mechanisms of microbial interactions and produce new knowledge about the pathogen Pseudomonas aeruginosa, a common cause of death in cystic fibrosis patients. We will characterise the interactions between P. aeruginosa and the emerging fungal pathogen Scedosporium aurantiacum as a proactive step towards be ....Future Industries Research - Biotechnology and Nanotechnology: Small talk: Communication networks in microbes. We will use the Australian Proteome Analysis Facility to address the multifaceted mechanisms of microbial interactions and produce new knowledge about the pathogen Pseudomonas aeruginosa, a common cause of death in cystic fibrosis patients. We will characterise the interactions between P. aeruginosa and the emerging fungal pathogen Scedosporium aurantiacum as a proactive step towards better understanding of pathogen communication. Improved understanding of pathogen interactions should facilitate the development of novel anti-adhesives as therapeutics. Our project will train young scientists in a new integrated approach to biology.Read moreRead less
Glycointeractions. This project aims to characterise two new classes of structural interactions with carbohydrates: carbohydrate-carbohydrate interactions and short alpha helical domains which can bind carbohydrates. Carbohydrate structures are found on the surface of cells in all forms of life. The intended outcome is to understand the molecular basis for these carbohydrate interactions. This information should provide an intellectual framework for understanding and manipulating these carbohydr ....Glycointeractions. This project aims to characterise two new classes of structural interactions with carbohydrates: carbohydrate-carbohydrate interactions and short alpha helical domains which can bind carbohydrates. Carbohydrate structures are found on the surface of cells in all forms of life. The intended outcome is to understand the molecular basis for these carbohydrate interactions. This information should provide an intellectual framework for understanding and manipulating these carbohydrate interactions, which underpin many processes in biological systems. The findings will inform the design of future drugs to block these interactions and will generate new tools for glycoscience.Read moreRead less
Tailoring cellulose properties by manipulating cellulose synthase. Cellulose, a highly abundant polymer produced by plants, has many existing uses in Australian fibre and polymer industries and potential uses as, for example, an abundant feedstuff for biomass conversion into ethanol and other high value products. The optimal properties for different applications vary so that, for example, high crystallinity cellulose gives strong fibres whereas low crystallinity cellulose dissolves in gentler so ....Tailoring cellulose properties by manipulating cellulose synthase. Cellulose, a highly abundant polymer produced by plants, has many existing uses in Australian fibre and polymer industries and potential uses as, for example, an abundant feedstuff for biomass conversion into ethanol and other high value products. The optimal properties for different applications vary so that, for example, high crystallinity cellulose gives strong fibres whereas low crystallinity cellulose dissolves in gentler solvents on the way to producing cellulose-based polymers. By exploring ways to adjust the properties of celluloses for use in different applications, we can deliver potential benefits to primary producers, industries and the environment.

Control of actin assembly by cell-cell adhesion: molecular effectors and higher order function. Functional cooperation between the actin cytoskeleton and cadherin cell-cell adhesion molecules plays critical roles during development and morphogenesis. This proposal builds on my lab's recent discovery that E-cadherin interacts with and regulates the Arp2/3 actin nucleator complex, a central determinant of actin assembly in cells. We will explore key implications of this finding, concentrating on d ....Control of actin assembly by cell-cell adhesion: molecular effectors and higher order function. Functional cooperation between the actin cytoskeleton and cadherin cell-cell adhesion molecules plays critical roles during development and morphogenesis. This proposal builds on my lab's recent discovery that E-cadherin interacts with and regulates the Arp2/3 actin nucleator complex, a central determinant of actin assembly in cells. We will explore key implications of this finding, concentrating on defining the molecular mechanisms that regulate Arp2/3 and actin assembly in cadherin-based adhesion. Our work combines molecular characterization of regulatory mechanisms and proteomic searches for new regulators, with tests of the higher-order function of this novel process in cell adhesion and recognition.Read moreRead less
