Breaking the nexus: more biomass in cereal grain. Grain yield is controlled by complex, regulated genetic networks or quantitative trait loci (QTLs) derived from natural variations in many crop plants. Yield is a product of the three major parameters: panicle number, grain number and grain size, trade-offs are commonly observed between grain number and size. There is evidence to suggest it is possible to improve grain size without altering overall biomass. With the genomic and genetic resource t ....Breaking the nexus: more biomass in cereal grain. Grain yield is controlled by complex, regulated genetic networks or quantitative trait loci (QTLs) derived from natural variations in many crop plants. Yield is a product of the three major parameters: panicle number, grain number and grain size, trade-offs are commonly observed between grain number and size. There is evidence to suggest it is possible to improve grain size without altering overall biomass. With the genomic and genetic resource tools at hand. This project will elucidate the genetic architecture of grain size, and manipulate the key loci to generate more biomass in the grain, minimising or eliminating the adverse impact on seed number. This will maximise harvestable yield without imposing increased demand for water and nutrients.Read moreRead less
A novel DNA motif involved in plant mitochondrial stress responses. The future of Australia's agriculture is threatened by limited water resources, temperature extremes and soil salinity. This project aims to unravel how plants are able to adapt to this continuously changing environment, by focusing on the role of mitochondria - cellular compartments essential for energy metabolism and plant stress responses.

Summary
How plants respond to cell wall signals. This project aims to discover mechanisms of plant cell wall signalling and modify plant cell walls for improved food, textiles, building materials and renewable biofuels without inadvertently activating cell wall signalling. However, attempts to improve cell walls have been ineffective because it is not known how plants use cell wall signalling to sense and compensate for cell wall changes. This project expects to develop both a genetic screen to find mut ....How plants respond to cell wall signals. This project aims to discover mechanisms of plant cell wall signalling and modify plant cell walls for improved food, textiles, building materials and renewable biofuels without inadvertently activating cell wall signalling. However, attempts to improve cell walls have been ineffective because it is not known how plants use cell wall signalling to sense and compensate for cell wall changes. This project expects to develop both a genetic screen to find mutants defective in cell wall signal transduction and a bioinformatic tool to compare genomes across species and discover cell wall signalling components. Potential benefits include addressing Australian research priorities: Food, Environmental Change, and Energy.Read moreRead less
Small molecules with large effect: The dual role of nitrogen-containing metabolites in stress tolerance and nutrient recycling. The main objective of this project is to identify drought and nutrient-deficiency responsive pathways in tolerant wheat and to provide markers to breeding programs that facilitate selection of superior breeding lines. This project builds on a pilot study conducted in rice in which tolerant-specific metabolites were identified which are representative of pathways relevan ....Small molecules with large effect: The dual role of nitrogen-containing metabolites in stress tolerance and nutrient recycling. The main objective of this project is to identify drought and nutrient-deficiency responsive pathways in tolerant wheat and to provide markers to breeding programs that facilitate selection of superior breeding lines. This project builds on a pilot study conducted in rice in which tolerant-specific metabolites were identified which are representative of pathways relevant for the protection of cells from damage through reactive oxygen species (ROS) and for nutrient (nitrogen, phosphorus, sugars) recycling under stress. Available data suggest that these pathways are also relevant in wheat. Quantitative metabolomics, genetics, and molecular tools will be used to deliver either DNA-based or metabolomics markers to breeders.Read moreRead less
Cereal blueprints for a water-limited world. This project aims to demonstrate that key developmental genes in cereals can be manipulated to design plant architecture for specific resource-limited environments. Producing more food with less water is one of the greatest challenges facing humanity today. This project expects to increase understanding of how shoot and root systems can be uncoupled to enhance crop adaptation in water-limited environments using an accelerated genome editing approach. ....Cereal blueprints for a water-limited world. This project aims to demonstrate that key developmental genes in cereals can be manipulated to design plant architecture for specific resource-limited environments. Producing more food with less water is one of the greatest challenges facing humanity today. This project expects to increase understanding of how shoot and root systems can be uncoupled to enhance crop adaptation in water-limited environments using an accelerated genome editing approach. An expected outcome of the project is enhanced drought adaptation for cereals in a dry world. This should provide significant benefits to farmers and consumers in Australia and worldwide.Read moreRead less
Functional analysis of novel mitochondrial outer membrane proteins in Arabidopsis. Mitochondria play central roles in the life and death of cells. This project will characterise the functions of proteins on the mitochondrial surface, which mediate signals that define mitochondrial function, providing novel approaches to modify mitochondrial function and plant growth.
The hunt for Ribonucleic Acid riboswitches and genetic sensors of metabolic flux in plants. Ribonucleic Acid (RNA) contains both structural and sequence information that coordinates feedback of metabolic processes in response to environmental change, thereby promoting cellular adaptation and survival. This project will discover ancient RNA modules and structural switches in plants that sense chemical reactions and regulate pathway flux.

This project aims to establish complementary scanning electron microscope (SEM) facilities at The University of Melbourne and LaTrobe University to advance research into crops, disease, neurosciences and coral reefs. SEMs are rapidly evolving instruments that permit high resolution imaging of visible size samples such as parts of plants and animals. The potential innovations, applications and benefits to society are far reaching, with the facility expected to impact the development of drought and salinity tolerance in crops, production of fibres by plants, resilience of Great Barrier Reef corals to warming, advances in medicinal agriculture, control of important diseases of livestock and humans, and sensory processing and ocular disease.Read moreRead less
Molecular basis of rust infection and host plant resistance. Plant diseases threaten agricultural productivity in Australia, with rust fungi being a major problem for cereal grain production. This project will investigate molecular processes underlying the infection of plants by rust fungi and will provide basic knowledge for development of novel and durable disease resistance strategies.
Extreme expression: building a platform for industrial plant biotechnology. Plants have remarkable potential as bioreactors for the production of usually non-plant compounds such as medical proteins, industrial proteins including enzymes and polymers. However, to realise this potential, there needs to be very significant advances in the amount of target compounds produced in the bioreactor plants and to develop other plant species as bioreactors. The aim of this project is to develop technologie ....Extreme expression: building a platform for industrial plant biotechnology. Plants have remarkable potential as bioreactors for the production of usually non-plant compounds such as medical proteins, industrial proteins including enzymes and polymers. However, to realise this potential, there needs to be very significant advances in the amount of target compounds produced in the bioreactor plants and to develop other plant species as bioreactors. The aim of this project is to develop technologies that provide the platform to produce large quantities of target novel compounds in plants and extend the range of plant species that can be used as bioreactors. These technologies will provide the basis of a dynamic biofarming industry in Australia.Read moreRead less
