Summary
Controlling chloride in plants. This project aims to discover novel components that control how plants acquire and manage chloride. Chloride is one of the two ions that commonly cause salt stress, which is a major threat to Australia’s agriculture. Regions affected by salinity are increasing worldwide due to changing weather patterns and poor land management. Knowledge of plant chloride management is underdeveloped, despite the reduction in crop yield caused by high chloride accumulation. The an ....Controlling chloride in plants. This project aims to discover novel components that control how plants acquire and manage chloride. Chloride is one of the two ions that commonly cause salt stress, which is a major threat to Australia’s agriculture. Regions affected by salinity are increasing worldwide due to changing weather patterns and poor land management. Knowledge of plant chloride management is underdeveloped, despite the reduction in crop yield caused by high chloride accumulation. The anticipated outcome of this project will inform strategies aimed at selecting for optimised chloride management traits to generate crops with improved yield.Read moreRead less

Summary
How does mitochondrial biogenesis regulate seed germination in plants? This project aims to develop a better understanding of seed germination to enable the generation of cereal seeds with optimised rates of germination for agricultural production. Seed germination is a fundamental phase of the plant life cycle. Every year, alterations in the rate of germination cause significant crop loss in rice and other cereals. Mitochondria are emerging as essential signalling hubs in the regulation of seed ....How does mitochondrial biogenesis regulate seed germination in plants? This project aims to develop a better understanding of seed germination to enable the generation of cereal seeds with optimised rates of germination for agricultural production. Seed germination is a fundamental phase of the plant life cycle. Every year, alterations in the rate of germination cause significant crop loss in rice and other cereals. Mitochondria are emerging as essential signalling hubs in the regulation of seed germination. The project aims to combine the latest technologies and molecular approaches with genetics to understand how mitochondria regulate seed germination and the rate of germination progression in rice. The project also plans to investigate and confirm the interplay between oxygen signalling, phytohormones and mitochondrial biogenesis.Read moreRead less
Control points in nitrogen uptake: enhancing the response of cereals to nitrogen supply and demand. Vast amounts of nitrogen fertiliser are applied to cereal crops to maintain yields. By uncovering what limits nitrogen uptake in cereals, this project will provide the scientific basis for improving nitrogen use efficiency and decreasing fertiliser use, with significant economic and environmental benefits.
Exploring genetic diversity to identify new heat tolerance genes in wheat. This project aims to improve the selection and development of heat-tolerant wheat varieties. Heatwaves seriously reduce wheat yields worldwide, and the situation will worsen with climate variation. This project aims to apply a broad genetic scan to identify the main chromosome regions controlling heat tolerance at the sensitive flowering stage in Australian and European wheat varieties. It is expected that this knowledge ....Exploring genetic diversity to identify new heat tolerance genes in wheat. This project aims to improve the selection and development of heat-tolerant wheat varieties. Heatwaves seriously reduce wheat yields worldwide, and the situation will worsen with climate variation. This project aims to apply a broad genetic scan to identify the main chromosome regions controlling heat tolerance at the sensitive flowering stage in Australian and European wheat varieties. It is expected that this knowledge will deliver crucial breeders’ tools to select heat-tolerant varieties. The project also aims to identify genes most likely to control tolerance at these chromosome locations using gene expression profiling data, trait associations and knowledge of heat-tolerance genes from other species. It is expected that these genes will reveal molecular mechanisms of heat tolerance and create new opportunities to engineer superior levels of tolerance in cereals.Read moreRead less
Mitochondrial Retrograde Signalling in Plants – New Models and Analytical Approaches. Mitochondria are essential organelles involved in energy production and various metabolic and biosynthetic pathways in plant cells. Signals from mitochondria act to regulate nuclear gene expression to coordinate mitochondrial activity with cellular activity, which is called mitochondrial retrograde signalling (MRS). To date our knowledge of the pathways and components involved in MRS is limited to a single mode ....Mitochondrial Retrograde Signalling in Plants – New Models and Analytical Approaches. Mitochondria are essential organelles involved in energy production and various metabolic and biosynthetic pathways in plant cells. Signals from mitochondria act to regulate nuclear gene expression to coordinate mitochondrial activity with cellular activity, which is called mitochondrial retrograde signalling (MRS). To date our knowledge of the pathways and components involved in MRS is limited to a single model system. This proposal seeks to identify additional MRS pathways, characterise components of these pathways and the signals involved. This new knowledge can be used in translational research as a basis to breed plants with altered stress and growth properties.Read moreRead less

Summary
Worth its salt: advancing knowledge of salinity tolerance with mangroves as a model system. This project aims to understand how salinity tolerance is achieved in mangroves, which are highly salt tolerant plants. Using a combination of physiological and gene expression technologies the project will measure the response of mangroves to elevated salinity and atmospheric carbon dioxide, contributing to the development of salt tolerant next generation crops.

Summary
Plant adaptation to extreme environments: a transcriptomic approach for crop improvement. Native Australian plants have evolved to thrive under multiple environmental stresses such as drought, salinity, and severely nutrient impoverished soils that define the Australian biomes. This project will reveal genetic components consistently found in such species, literally opening a new gateway to greener pastures for Australian agriculture.
The role of chlorophyll f in photosynthesis. The knowledge of energetic limits of oxygenic photosynthesis will provide opportunities for improving the efficiency of photosynthesis by using a wider range of the solar spectrum. This project aims to understand the roles of newly discovered chlorophyll f in central photoreactions and its biosynthesis.
