Plant species vary widely in quantitative functional traits, and in their relations to climate, soils and geography. Global generalizations are emerging. Vegetation Function network will reach from plant function into genomics and crop breeding, into palaeoecology and vegetation history, into landscape management for carbon, water and salinity outcomes, into forecasting future ecosystems under global change, and into phylogeny, ecoinformatics and evolutionary theory. Across this span, working groups will target nine identified opportunities for breakthrough research. Each research target needs input from two or more disciplines. Together, the nine targets link across disciplines, as a network that spans from genomic to planetary scales.Read moreRead less

Summary
High-throughput sample preparation robotics to enable emerging large-scale plant genomics, metabolomics and proteomics research. Discovering and breeding plants that are best suited for new environmental conditions requires the analysis of many samples to discover the underlying genes, metabolites and proteins. The project will build two robotic instruments that will facilitate the rapid grinding and extraction of plant tissues to facilitate these discoveries across Australia.
Turning water into carbon: a synthesis of plant water-use efficiency from leaf to globe. The efficiency with which plants use water to gain carbon is a fundamental aspect of plant growth that has been frequently measured but is poorly understood. Using our new theory to draw together major datasets, the project will make a dramatic advance in our ability to understand and predict this key aspect of ecosystem function.
Answering longstanding plant ecology questions with new technology: the effects of changes in leaf proteins with age. Total leaf nitrogen is important for major processes in ecosystems. It is used as a predictor for carbon fixation because photosynthesis proteins are a large fraction of leaf nitrogen. Yet leaf nitrogen may also be allocated to stress-response and defense-related proteins at the expense of photosynthesis proteins. Our working hypothesis might explain two important ecological patt ....Answering longstanding plant ecology questions with new technology: the effects of changes in leaf proteins with age. Total leaf nitrogen is important for major processes in ecosystems. It is used as a predictor for carbon fixation because photosynthesis proteins are a large fraction of leaf nitrogen. Yet leaf nitrogen may also be allocated to stress-response and defense-related proteins at the expense of photosynthesis proteins. Our working hypothesis might explain two important ecological patterns: the decline of photosynthetic nitrogen use efficiency with leaf age; and, low and variable nitrogen recovery levels from senescent leaves across species and habitats. New quantitative proteomics methods together with protein functional categorisation can answer these questions across dozens of Australian native plant species.Read moreRead less
Invasive plant success and multi-trophic level chemical ecology using Paterson's curse as a model. The role of plant defence compounds discovered recently in Paterson's curse will be studied in the plant's native western Mediterranean and in southern Australia. Findings will support biological control efforts and provide fundamental insights into the ecological mechanisms that allow such plants to become aggressive invaders.
How do plants cope with temporal variability in water and nutrients? Australia's climate and weather are temporally variable, yet we know little of how Australia's flora is affected by temporally variable vs constant supplies of water and nutrients. In addition, climate change will affect our flora by, among other things, increasing temporal variability in water and nutrient availability. This program of research will provide basic data on growth responses to variable vs. constant water and nu ....How do plants cope with temporal variability in water and nutrients? Australia's climate and weather are temporally variable, yet we know little of how Australia's flora is affected by temporally variable vs constant supplies of water and nutrients. In addition, climate change will affect our flora by, among other things, increasing temporal variability in water and nutrient availability. This program of research will provide basic data on growth responses to variable vs. constant water and nutrient availability. Hence, results will be directly applicable to predicting the effects of climate change on growth, species' distribution and community composition. This research will also improve our basic understanding of limitations to photosynthesis, transpiration and nutrient uptake/assimilation.Read moreRead less
