This project aims to explore metabolic diversity of Klebsiella pneumoniae, a bacterium relevant to the agricultural, veterinary, medical and biotechnology industries. It is expected to reveal significant insights into the biology of this diverse organism via an innovative combination of DNA sequence analyses and metabolic modelling. Expected outcomes include 4500 novel metabolic models and a novel population metabolic framework. This should provide major benefits for understanding bacterial ecology and evolution, and for future studies seeking to optimise industrial processes or prevent disease. It will also directly contribute to building Australia’s capacity in computational biology- a key driver of biotechnology innovation.Read moreRead less
Using venoms to map critical and evolutionary conserved vulnerabilities. We have developed and applied new functional genomic approaches to study venom evolution. Using CRISPR screening, we find that unrelated venoms act on cells by exploiting the same vulnerabilities. By functionally mapping these vulnerabilities for all venom classes, we can begin to develop universal venom antidotes. Conversely, much of what we know about venom mechanisms comes from a small percentage of the biodiversity with ....Using venoms to map critical and evolutionary conserved vulnerabilities. We have developed and applied new functional genomic approaches to study venom evolution. Using CRISPR screening, we find that unrelated venoms act on cells by exploiting the same vulnerabilities. By functionally mapping these vulnerabilities for all venom classes, we can begin to develop universal venom antidotes. Conversely, much of what we know about venom mechanisms comes from a small percentage of the biodiversity within a venom, and we have developed genomic tools to study the venom “dark matter”. This work will lead to the full molecular characterisation of venom biodiversity, and new venom components will be useful for research or as novel medicines.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
Haplodiploidy: the great evolutionary innovation of the Hymenoptera. This project aims to identify a key gene that causes thelytokous parthenogenesis. Thelytoky is the ability of a female to clone herself (virgin birth), and is wide spread in the Hymenoptera which include bees, wasps and ants. Hymenopteran thelytoky is important because it facilitates some major transitions in life history, particularly social parasitism. The capacity for virgin birth is central to the invasiveness of many ant s ....Haplodiploidy: the great evolutionary innovation of the Hymenoptera. This project aims to identify a key gene that causes thelytokous parthenogenesis. Thelytoky is the ability of a female to clone herself (virgin birth), and is wide spread in the Hymenoptera which include bees, wasps and ants. Hymenopteran thelytoky is important because it facilitates some major transitions in life history, particularly social parasitism. The capacity for virgin birth is central to the invasiveness of many ant species, and enables social cancers (parasitic workers that kill colonies) in bees. The benefit of this project is that the identification of the gene should help identify potentially invasive ant species and help prevent the social cancers that affect commercial beekeeping in South Africa from spreading world-wide.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.

The molecular evolution of wings in flightless birds. The flightless Australian emu and New Zealand kiwi have small wings, while the extinct moa had none at all. This project will identify the genetic changes that have lead to wing reduction and loss in flightless birds. The results will shed light on the genetic control of forelimb development and how it has evolved.

Summary
Historical pest genomes inform debate about how rapid evolution proceeds. This project plans to compare the genomes of archived and contemporary specimens to discover how two key Australian pest moths have adapted to insecticides, aiding prediction of how they may respond in the future. Agricultural pest species are often capable of rapid adaptation to insecticides, resulting in widespread genetic resistance. Does this resistance build on existing genetic variation, or are fresh mutations used t ....Historical pest genomes inform debate about how rapid evolution proceeds. This project plans to compare the genomes of archived and contemporary specimens to discover how two key Australian pest moths have adapted to insecticides, aiding prediction of how they may respond in the future. Agricultural pest species are often capable of rapid adaptation to insecticides, resulting in widespread genetic resistance. Does this resistance build on existing genetic variation, or are fresh mutations used to produce a fast adaptive response? How do adaptive strategies differ among key Australian pests? This project aims to answer these questions and advance understanding of mechanisms that underpin rapid evolution to improve approaches toward pest management and agricultural protection.Read moreRead less
Genome-wide determination of Puccinia psidii s.l. rust resistance in eucalypts. Recently, guava rust was detected in Australia, posing significant risks to native flora, plantations, and timber exports. Scientists from The University of Melbourne and Victorian Department of Primary Industries together with tree breeders, forest growers and forest managers aim to use tree genomics rust resistance breeding to enable management and operational responses and inform policy development.
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
The evolutionary origin, cellular response and genetic impact of insecticide resistance mutations in agricultural pests. Diamondback moth is a global pest of canola and Brassica vegetables, and populations can rapidly evolve resistance to insecticides. The project will use a combination of genome sequencing, fieldwork and gene expression analysis to identify mutations causing resistance to Bt insecticidal toxins and assess the threat of resistance evolving in Australia.
