Tree-mediated methane fluxes: A new frontier in the global carbon cycle. Methane is an extremely potent greenhouse gas. Recent evidence suggests that tree-mediated fluxes may be a significant, but overlooked source of methane to the atmosphere. This project aims to quantify the magnitude and drivers of tree-mediated methane fluxes from Australia’s dominant forest types. Innovatively, we will be using a novel combination of empirical field based measurements, gas tracer experiments, microbial ana ....Tree-mediated methane fluxes: A new frontier in the global carbon cycle. Methane is an extremely potent greenhouse gas. Recent evidence suggests that tree-mediated fluxes may be a significant, but overlooked source of methane to the atmosphere. This project aims to quantify the magnitude and drivers of tree-mediated methane fluxes from Australia’s dominant forest types. Innovatively, we will be using a novel combination of empirical field based measurements, gas tracer experiments, microbial analysis and modelling methods. Expected outcomes are a mechanistic understanding of tree-mediated methane fluxes, helping to constrain regional, national and global methane budgets. The results of this study will help inform publicly funded greenhouse gas abatement strategies, ensuring a maximal return on investment.Read moreRead less
Protein biosensors for detecting smoke exposure of grapes. Bush fires and controlled burns that take place in the vicinity of vineyards can lead to grape contamination with tasteless phenolic glucosides. Their hydrolysis during wine making leads to “smoke taint” – an unpleasant medicinal taste that can render wine undrinkable. We will apply a combination of organic synthesis, protein engineering and directed evolution to develop protein-based biosensors of phenolic glucosides. These biosensors w ....Protein biosensors for detecting smoke exposure of grapes. Bush fires and controlled burns that take place in the vicinity of vineyards can lead to grape contamination with tasteless phenolic glucosides. Their hydrolysis during wine making leads to “smoke taint” – an unpleasant medicinal taste that can render wine undrinkable. We will apply a combination of organic synthesis, protein engineering and directed evolution to develop protein-based biosensors of phenolic glucosides. These biosensors will be used to devise a simple portable colorimetric test that can be performed in the vineyard or the winery. The ability to rapidly determine the level of grape contamination with phenolic glucosides would give Australian wine growers and wine makers a powerful tool to mitigate the effects of bushfires.Read moreRead less

This project aims to explain the past and protect the present biodiversity of endangered marsupial mammals such as bilbies and koalas. It will generate new knowledge using an interdisciplinary combination of 3D analysis of skull shape, reflecting a mammal’s ability to feed and sense its surrounds, with the fast-moving fields of marsupial conservation and evolutionary genetics. This will help to anticipate if, and how, changing environments and declining numbers reduce these species’ ability to adapt. Benefits include better information to support improved conservation decisions and identification of genes underlying the evolution of marsupial skull diversity.Read moreRead less

Safer gene editing tools for Australian livestock and biotech industries. Editing the genome of an organism in an efficient and safe fashion is critical for the livestock and biotechnology industries. While CRISPR-Cas9 has become the method of choice for genome editing, it is known to introduce unwanted "on-target" and "off-target" mutations, limiting its utility. To address this the CI team created a novel genome editing platform technology termed Crackling-CAST that is almost 100% accurate, w ....Safer gene editing tools for Australian livestock and biotech industries. Editing the genome of an organism in an efficient and safe fashion is critical for the livestock and biotechnology industries. While CRISPR-Cas9 has become the method of choice for genome editing, it is known to introduce unwanted "on-target" and "off-target" mutations, limiting its utility. To address this the CI team created a novel genome editing platform technology termed Crackling-CAST that is almost 100% accurate, while retaining the efficiency of the classical Cas9 system. This project will exemplify the capabilities of the novel gene targeting platform in cell types used by the biotechnology and livestock sectors, ensuring its global uptake by these industries and delivering significant economic benefits for Australia.
