Identification of Biological pathways regulated by circular RNAs. Circular RNAs (circRNAs) are a, recently discovered molecule. circRNAs are highly abundant and expressed in a tissue and disease specific manner. Yet, currently the understanding of how circRNAs regulate biological processes is very poor. This project aims to use pooled shRNA libraries to screen a large panel of cell lines and systematically identify cellular activities that are regulated by circRNAs.

Circular RNAs (circRNAs) are a, recently discovered molecule. circRNAs are highly abundant and expressed in a tissue and disease specific manner. Yet, currently the understanding of how circRNAs regulate biological processes is very poor. This project aims to use pooled shRNA libraries to screen a large panel of cell lines and systematically identify cellular activities that are regulated by circRNAs. The expected outcome of this study will be a catalogue of functionally active circRNAs. Over the past decades, the wealth of knowledge on the function of linear mRNAs has had a significant impact on medicine and agriculture. Similarly understanding how circRNAs regulate cellular activities may have an analogous impact on humans.Read moreRead less

Molecular biosecurity: Genomic databanks for managing new pest invasions. This project aims to develop a set of genomics-based approaches for analysing new pest invasions. By producing and analysing genomic databanks for four insect pest species, including three that have recently invaded Australia, this project expects to identify invasion origins and to track new pest incursions within Australia. The project should also provide insights into pest ecology, including movement rates and populatio ....Molecular biosecurity: Genomic databanks for managing new pest invasions. This project aims to develop a set of genomics-based approaches for analysing new pest invasions. By producing and analysing genomic databanks for four insect pest species, including three that have recently invaded Australia, this project expects to identify invasion origins and to track new pest incursions within Australia. The project should also provide insights into pest ecology, including movement rates and population change over time. This information can enable more efficient deployment of biosecurity resources and pave the way for genomics to be used pre-emptively to stop new invasions. This can help make genomics a go-to response to new pest invasions and position Australia at the forefront of genomics-based pest biosecurity.Read moreRead less

Redefining virus ecology and evolution. This project aims to employ novel genomic analyses of viruses from Australian fauna to resolve major questions in RNA virus ecology and evolution, and is expected to reveal the basic processes that shape the virosphere, determine how viruses jump species to emerge and cause disease in new hosts, and how viruses evolve new levels of virulence. The research will provide a new understanding of how viruses evolve and contribute to global ecosystems and develop ....Redefining virus ecology and evolution. This project aims to employ novel genomic analyses of viruses from Australian fauna to resolve major questions in RNA virus ecology and evolution, and is expected to reveal the basic processes that shape the virosphere, determine how viruses jump species to emerge and cause disease in new hosts, and how viruses evolve new levels of virulence. The research will provide a new understanding of how viruses evolve and contribute to global ecosystems and develop new bioinformatics tools to identify and analyse highly divergent genome sequences through studying meta-transcriptomic data from diverse animal phyla, from prokaryotes and basal eukaryotes, from iconic native mammalian species and their major invasive pests. The benefits provided will include determining the viromes of native and invasive species and enhancing the efforts to protect iconic Australian species from infectious disease.Read moreRead less
Real-time phylogenetics for food-borne outbreak surveillance. The project aims to introduce, for the first time, real-time evolutionary analysis of agricultural pathogens so that outbreaks affecting crops and the food supply can be managed precisely and rapidly. An expert team will implement a large-scale data analytics framework in user-friendly software that integrates Australian infectious disease genomics data with global data. Underpinning this work are new theory and algorithms that apply ....Real-time phylogenetics for food-borne outbreak surveillance.

An expert team will implement a large-scale data analytics framework in user-friendly software that integrates Australian infectious disease genomics data with global data. Underpinning this work are new theory and algorithms that apply Sequential Monte Carlo to update phylogenetic analyses continuously as new data arrives. Expected outcomes include new knowledge of statistical algorithms for evolutionary analysis, relevant to biological disciplines beyond infectious disease; and enhanced capacity for infectious disease analysis.

Summary
A walk on the wild side: understanding disease resistance across plants. Plants are in constant battle with pests and pathogens. Wild species host genetic diversity, providing sources of disease resistance, while the narrow genetic base of crop varieties leads to an increasing reliance on the unsustainable application of chemical fungicides. Here I will apply the latest genomics approaches to characterise disease resistance gene diversity across the plant kingdom. Comparison of gene diversity wi ....A walk on the wild side: understanding disease resistance across plants. Plants are in constant battle with pests and pathogens. Wild species host genetic diversity, providing sources of disease resistance, while the narrow genetic base of crop varieties leads to an increasing reliance on the unsustainable application of chemical fungicides. Here I will apply the latest genomics approaches to characterise disease resistance gene diversity across the plant kingdom. Comparison of gene diversity within and between plant families will improve our understanding of resistance gene evolution in wild species and the impact of domestication and breeding on resistance gene diversity. Translation of this knowledge will support breeding for crop resilience, leading to durable resistance and more sustainable crop productionRead moreRead less
Investigating a novel genetic strategy for insect resistance in crops. Plants are in a constant battle with insect pests and there is an increasing reliance on chemical inputs for control. However there are incoming bans on some pesticides, and new approaches are required for pest management. The aim of this project is to develop a new strategy which exploits the dependence of herbivorous insects on phytosterols. Here, we will apply the latest genomics technologies in plants to produce non-utili ....Investigating a novel genetic strategy for insect resistance in crops. Plants are in a constant battle with insect pests and there is an increasing reliance on chemical inputs for control. However there are incoming bans on some pesticides, and new approaches are required for pest management. The aim of this project is to develop a new strategy which exploits the dependence of herbivorous insects on phytosterols. Here, we will apply the latest genomics technologies in plants to produce non-utilizable sterols which will not support insect growth and reproduction, but will still allow the plant to function normally. We will demonstrate this in the important crop canola. Translation of this knowledge will support breeding for crop resilience, leading to durable resistance and more sustainable crop production.Read moreRead less
Optimising plant populations for ecological restoration and resilience. When choosing individual plants for restoration populations, there is potentially a trade-off between maximising genetic diversity (‘adaptability’) and selection for desirable properties (‘adaptation’). This project aims to develop pioneering methods to quantify this trade-off, and facilitate the design of optimised populations, with a focus on two Australian rainforest trees that are being impacted by myrtle rust infection: ....Optimising plant populations for ecological restoration and resilience. When choosing individual plants for restoration populations, there is potentially a trade-off between maximising genetic diversity (‘adaptability’) and selection for desirable properties (‘adaptation’). This project aims to develop pioneering methods to quantify this trade-off, and facilitate the design of optimised populations, with a focus on two Australian rainforest trees that are being impacted by myrtle rust infection: Rhodamnia argentea and Rhodamnia rubescens. By studying the genetic variation in each species, and how this relates to myrtle rust resistance and climate, this project aims to design populations that are genetically diverse, maximally resistant to myrtle rust, and adapted to future climate.Read moreRead less
