Can we engineer plants to grow on salty soils? This project aims to answer questions about how plants can sustain their growth on salty soils. Plant-derived products constitute a pillar for our society. However, crop yields may be severely penalised due to unfavourable growth conditions, including soil salinity. This is particularly relevant for Australia as a large fraction of its arable land is affected by salt. This project aims to use molecular and cell biology techniques to resolve mechanis ....Can we engineer plants to grow on salty soils? This project aims to answer questions about how plants can sustain their growth on salty soils. Plant-derived products constitute a pillar for our society. However, crop yields may be severely penalised due to unfavourable growth conditions, including soil salinity. This is particularly relevant for Australia as a large fraction of its arable land is affected by salt. This project aims to use molecular and cell biology techniques to resolve mechanisms of how the synthesis of cellulose, which constitutes the bulk of a plant's biomass, is maintained in plants during salt stress. This project has potential for climate change mitigation, enhanced plant biomass production and improved fuel security.Read moreRead less

This project aims to develop single-cell algae optimised for high-efficiency green hydrogen production from cheap, sustainable resources - sunlight and water. The success of this project would be a game changer for industry by dramatically improving light to fuel conversion efficiencies. The expected high-efficiency cells would be a valuable resource for a wide range of other light-driven advanced bio-manufacture applications from high-value biopharmaceuticals (e.g. <10 Hectare scale) through to renewable fuels (e.g. 10-1000 Hectare regional scale). The benefits would include advanced green chemical and biochemical manufacturing, diversified sources for green H2 production, regional development, industry growth, job security and exports.Read moreRead less
Deciphering the Thermal Acclimation of Mitochondrial Respiration. Plants acclimate to the extremes of temperature following a pre-exposure to a sub-lethal increase/decrease in temperature. Recent research has revealed that proteins of oxidative phosphorylation and the tricarboxylic acid (TCA) cycle are dynamic and change their abundance in response to temperature change. Harnessing a cutting edge protein mass spectrometry approach, this project seeks to better understand how mitochondrial respir ....Deciphering the Thermal Acclimation of Mitochondrial Respiration. Plants acclimate to the extremes of temperature following a pre-exposure to a sub-lethal increase/decrease in temperature. Recent research has revealed that proteins of oxidative phosphorylation and the tricarboxylic acid (TCA) cycle are dynamic and change their abundance in response to temperature change. Harnessing a cutting edge protein mass spectrometry approach, this project seeks to better understand how mitochondrial respiration and hence adenosine triphosphate (ATP) production is maintained during temperature change. Uniquely this project will examine this in both the model plant Arabidopsis and wheat and combine both tissue, environment-induced and genotype variation to reveal a new understanding of the thermal acclimation of this major mitochondrial process.Read moreRead less

The quick and the dead: identifying mechanisms for plant drought survival. This project aims to identify genes that control plant responses to low air humidity, which enhance drought survival by restricting water loss. Most plant water loss occurs through pores called stomata. This project expects to identify the genes that close stomata within minutes of decreased humidity by determining the molecular changes that occur over this timeframe and testing candidate genes for a critical role. Divers ....The quick and the dead: identifying mechanisms for plant drought survival. This project aims to identify genes that control plant responses to low air humidity, which enhance drought survival by restricting water loss. Most plant water loss occurs through pores called stomata. This project expects to identify the genes that close stomata within minutes of decreased humidity by determining the molecular changes that occur over this timeframe and testing candidate genes for a critical role. Diverse land plant models will be examined to ensure broad applicability of results. A major expected outcome is new knowledge of genes that minimise plant water loss, which would ultimately benefit plant-based industries through new targets for breeding improved, drought-adapted varieties for food security in a drying climate.Read moreRead less

Summary
Proteomic analysis of thermal response in plants. This project will identify macromolecules that regulate temperature response in plants. Understanding how plants perceive changes in temperature will allow crop improvement in the face of likely increasing temperatures.
Advanced solar powered hydrogen production systems based on green algal cells. This project aims to enhance the efficiency of solar powered hydrogen production from water and will facilitate the co-production of H2 and oil through microalgal biofuel systems. This frontier science project will therefore deliver a process with high solar conversion efficiency and will deliver multiple product streams increasing profitability.
Environmental regulation of root architecture by a gene controlling auxin transport. This project will study the function of a gene that we found to control root branching in response to the availability of nutrients in the environment. This could lead to new strategies for breeding of crop plants with improved ability to withstand environmental change.
Modelling policy interventions to protect Australia's food security in the face of environmental sustainability challenges . This project will use an innovative scenario modelling approach to quantify the potential impacts of population growth and emerging climate and environmental challenges on Australia’s future food security. In collaboration with an advisory committee it will specify and prioritise policy solutions in terms of their social and economic credentials.
