Exploring the gene regulation networks governing mitochondrial biogenesis in Arabidopsis. Mitochondria, subcellular organelles that perform many functions indispensable to plant growth and productivity, are dynamic compartments whose protein complement changes dramatically during plant development and under stress. Yet, the cellular processes that regulate the production of these organelles are virtually unknown. By combining conventional approaches with an extremely powerful holistic method for ....Exploring the gene regulation networks governing mitochondrial biogenesis in Arabidopsis. Mitochondria, subcellular organelles that perform many functions indispensable to plant growth and productivity, are dynamic compartments whose protein complement changes dramatically during plant development and under stress. Yet, the cellular processes that regulate the production of these organelles are virtually unknown. By combining conventional approaches with an extremely powerful holistic method for simultaneously examining the expression patterns of every gene in the model plant Arabidopsis, this project will identify proteins that regulate mitochondrial biosynthesis and uncover the gene networks that these proteins control. The project outcomes will provide new opportunities for the rational manipulation of plant growth and productivity.Read moreRead less
Protein Complexes and Supercomplexes of Plant Organelles. Ample parts of plant primary metabolism occur in subcellular structures called mitochondria, plastids and peroxisomes. They are vital for plant growth and development and are central to the early success of germinating and growing seedlings. This project intends to analyze the protein complexes and supercomplexes within these organelles using state of the art instrumentation and technologies. Findings from this research have the potential ....Protein Complexes and Supercomplexes of Plant Organelles.

This project intends to analyze the protein complexes and supercomplexes within these organelles using state of the art instrumentation and technologies. Findings from this research have the potential to directly flow into the plant biotechnology industry and could assist the future development of Australian agriculture through genetic improvements. The expertise developed by this work will ensure that Australia is well placed to meet future needs and to generally improve agricultural technology. Read moreRead less

Summary
Oxidative stress bioanalytical facility. The primary national benefit of this application is that it will provide a currently unavailable, state-of-the-art facility for Australian scientists to define precisely how changes in cellular redox state contribute to biological processes relevant to health and diseases. The facility will uniquely complement, and in many cases integrate with existing facilities in this area of research in Australia. It will act as a platform for major national and inter ....Oxidative stress bioanalytical facility. The primary national benefit of this application is that it will provide a currently unavailable, state-of-the-art facility for Australian scientists to define precisely how changes in cellular redox state contribute to biological processes relevant to health and diseases. The facility will uniquely complement, and in many cases integrate with existing facilities in this area of research in Australia. It will act as a platform for major national and international research collaborations, develop cutting-edge technology and unique local skills, and contribute to Australia maintaining a leading position in redox-related research in biology and medicine. In doing so, the facility will increase the likelihood of gaining future, value-adding funding.Read moreRead less
Adaptations of plant mitochondria during cold acclimation in Arabidopsis thaliana: towards an understanding of plant cold acclimation. Frost damage is a major cost to agricultural producers and some crop plant species needlessly adapt to cold, when they are grown in temperate regions or in glasshouses, which leads to decreased production. The principal outcome of this project will be to greatly extend our knowledge about plant mitochondrial responses to environmental cold stress and what role th ....Adaptations of plant mitochondria during cold acclimation in Arabidopsis thaliana: towards an understanding of plant cold acclimation. Frost damage is a major cost to agricultural producers and some crop plant species needlessly adapt to cold, when they are grown in temperate regions or in glasshouses, which leads to decreased production. The principal outcome of this project will be to greatly extend our knowledge about plant mitochondrial responses to environmental cold stress and what role they have in helping plants adapt to environmental change. An understanding of cold acclimation may allow the production of plants with altered cold acclimation phenotypes and greater frost tolerance.Read moreRead less
Sex, Sperm and Society. Insights into the evolutionary potential of sexual conflict in insects: a fundamental question in evolutionary biology. Social insects are biologically and economically important species. Honeybees or stingless bees are used for crop pollination and honey production and invasive ants or termites are severe pest species causing economic damage. Part of the biological success of social insects is based on the capability to produce colonies with many workers although colonie ....Sex, Sperm and Society. Insights into the evolutionary potential of sexual conflict in insects: a fundamental question in evolutionary biology. Social insects are biologically and economically important species. Honeybees or stingless bees are used for crop pollination and honey production and invasive ants or termites are severe pest species causing economic damage. Part of the biological success of social insects is based on the capability to produce colonies with many workers although colonies typically contain only one or very few reproductives. Consequently, colony success is bound to queen fertility and studying social insect reproduction can therefore optimize breeding regimes of species of interest or offer new possibilities to control pest species. Detailed information on sperm form and function will provide pioneering insights into the complexity of sexual reproduction.Read moreRead less
