Tree-mediated methane fluxes: A new frontier in the global carbon cycle. Methane is an extremely potent greenhouse gas. Recent evidence suggests that tree-mediated fluxes may be a significant, but overlooked source of methane to the atmosphere. This project aims to quantify the magnitude and drivers of tree-mediated methane fluxes from Australia’s dominant forest types. Innovatively, we will be using a novel combination of empirical field based measurements, gas tracer experiments, microbial ana ....Tree-mediated methane fluxes: A new frontier in the global carbon cycle. Methane is an extremely potent greenhouse gas. Recent evidence suggests that tree-mediated fluxes may be a significant, but overlooked source of methane to the atmosphere. This project aims to quantify the magnitude and drivers of tree-mediated methane fluxes from Australia’s dominant forest types. Innovatively, we will be using a novel combination of empirical field based measurements, gas tracer experiments, microbial analysis and modelling methods. Expected outcomes are a mechanistic understanding of tree-mediated methane fluxes, helping to constrain regional, national and global methane budgets. The results of this study will help inform publicly funded greenhouse gas abatement strategies, ensuring a maximal return on investment.Read moreRead less
CENTRE for INTEGRATIVE LEGUME RESEARCH. Legumes are essential for environmental sustainability and are important for maintaining human health. The Centre combines innovative genomic approaches to investigate the causal phenotypic links required for regulation of legume growth. The unique coexistence of multiple pluripotent meristems in shoots, roots, flowers and nodules permits the discovery of new paradigms governing legume architecture, reproductive differentiation and root-nodule developmen ....CENTRE for INTEGRATIVE LEGUME RESEARCH. Legumes are essential for environmental sustainability and are important for maintaining human health. The Centre combines innovative genomic approaches to investigate the causal phenotypic links required for regulation of legume growth. The unique coexistence of multiple pluripotent meristems in shoots, roots, flowers and nodules permits the discovery of new paradigms governing legume architecture, reproductive differentiation and root-nodule development. New knowledge of the plant growth processes through mechanistic analysis of organ induction provides the tools to optimise the legume's productivity, quality, and environment adaptation.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.
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
