Plant cell metabolism underlies the synthesis of important products in crops, and subtle changes in metabolism can enhance germination rates, early seedling vigour, biomass/yield, and tolerance to harsh environments. Research in CPEB will focus on control of this metabolism. Its expertise will enhance Australia's participation in major international research efforts directly relevant to sustainable agriculture in a country with fragile/degrading ecosystems. The research will provide new approaches for enhancing quality metabolite traits important for human health. It will further strengthen our international leadership in plant energy science, and will strengthen Australia's research training in systems biology to influence plant function.Read moreRead less
Identifying genes controlling the regulatory and metabolic interactions between the energy organelles of the leaf. Plant energy metabolism underlies the synthesis of many important products in crops, and subtle changes in metabolism can enhance key plant traits, such as germination rates, early seedling vigour, biomass/yield, and tolerance to harsh environments.

Plant energy metabolism underlies the synthesis of many important products in crops, and subtle changes in metabolism can enhance key plant traits, such as germination rates, early seedling vigour, biomass/yield, and tolerance to harsh environments. Furthering our understanding on the complex interplay of genes controlling energy metabolism and its impact on leaf function has potential outcomes for smart genetic manipulation either by classical breeding or genetic transformation. There are more than 10,000 genes of unknown function in plant genomes and this represents a tremendous untapped resource for future Australian R&D outcomes and insights from this research proposal will have application to all plant-based agriculture.Read moreRead less
Comparative Biophysical Studies on Photosystem II of Higher Plants and Cyanobacteria. Photosystem II (PS-II) is one of two light trapping protein assemblies involved in the conversion of light into metabolic energy in all plants and algae. The manganese containing active site of PS-II is responsible for oxygen formation from water. The organisation and functioning of this centre and the detailed mechanism of photochemical energy conversion are not understood. This project will employ a combinati ....Comparative Biophysical Studies on Photosystem II of Higher Plants and Cyanobacteria. Photosystem II (PS-II) is one of two light trapping protein assemblies involved in the conversion of light into metabolic energy in all plants and algae. The manganese containing active site of PS-II is responsible for oxygen formation from water. The organisation and functioning of this centre and the detailed mechanism of photochemical energy conversion are not understood. This project will employ a combination of powerful biophysical techniques to probe the structure and mechanism of PS-II as a knowledge base for eventual genetic manipulation of plants and stategies for artificial photosynthesis.Read moreRead less
Unsaturation of vapour pressure inside leaves: fundamental, but unknown. This project aims to determine when and to what extent the air inside leaves becomes unsaturated with water vapour. All current interpretation and modelling of leaf gas exchange assumes saturation under all circumstances. Compelling evidence has been obtained that suggests this is not true under moderate air vapour pressure deficits. A novel technique will be employed to assess the water vapour concentration of the air insi ....Unsaturation of vapour pressure inside leaves: fundamental, but unknown. This project aims to determine when and to what extent the air inside leaves becomes unsaturated with water vapour. All current interpretation and modelling of leaf gas exchange assumes saturation under all circumstances. Compelling evidence has been obtained that suggests this is not true under moderate air vapour pressure deficits. A novel technique will be employed to assess the water vapour concentration of the air inside leaves based on stable isotope analysis of carbon dioxide and water vapour exchanged between leaves and air. The project is expected to provide fundamental knowledge about how stomata regulate photosynthesis and water use, with significant implications for modelling vegetation function and for improving the performance of crop plants.Read moreRead less
Functional genomics of light stress resistance in the model organism Chlamydomonas: combining molecular genetics, transcriptome and proteome analysis. This project aims at combining molecular genetics, transcriptome and proteome analysis to identify genes and pathways underlying high light stress tolerance in previously isolated mutants of the chlorophyte Chlamydomonas reinhardtii.

This project aims at combining molecular genetics, transcriptome and proteome analysis to identify genes and pathways underlying high light stress tolerance in previously isolated mutants of the chlorophyte Chlamydomonas reinhardtii. Comprehensive profiles of transcriptome-proteome linkage will be constructed without the complications of multicellularity for this unicellular photosynthetic model organism. We will establish a public proteome reference database and provide new microarrays and molecular markers beneficial for research in Chlamydomonas. We expect to advance understanding of high light resistance mechanisms so that it will eventually be applicable to improve productivity in crop plants growing under various environmental stress conditions.Read moreRead less
Novel photoprotective mechanisms and functional biodiversity of high light tolerance in the model alga Chlamydomonas. Most plants have limited capacity to avoid high light (HL) stress which commonly accompanies drought and high temperature stress. We will identify novel genes and proteins that underlie diverse mechanisms of photoprotection in unique very high light resistant (VHLR) mutants in the alga Chlamydomonas and develop new tools to screen other plants for these attributes. Depending on p ....Novel photoprotective mechanisms and functional biodiversity of high light tolerance in the model alga Chlamydomonas. Most plants have limited capacity to avoid high light (HL) stress which commonly accompanies drought and high temperature stress. We will identify novel genes and proteins that underlie diverse mechanisms of photoprotection in unique very high light resistant (VHLR) mutants in the alga Chlamydomonas and develop new tools to screen other plants for these attributes. Depending on progress, we expect to express them in the higher plant Arabidopsis as a first step towards utilization of VHLR genes for crop improvement. Understanding the mechanisms conferring HL photoprotection is a research priority in plant sciences and will further strengthen Australia's innovative contributions to the internationally networked Chlamydomonas Genome Project.Read moreRead less

Will stomatal responses to humidity and carbon dioxide constrain tropical forest productivity as atmospheric carbon dioxide rises? This project will investigate two physiological processes that will partly determine growth responses of tropical forest trees to rising atmospheric carbon dioxide. The project will produce equations summarising physiological responses that can be incorporated into process-based models of tropical forest productivity.
Reading the isotopic archive: carbon and oxygen stable isotope ratios as recorders of plant physiological processes. This project will investigate how plant physiological processes are reflected in stable isotope ratios of carbon and oxygen in plant tissues. Results will contribute towards a mechanistic understanding of the processes that cause isotopic modifications, thereby enabling an improved interpretation of naturally occurring stable isotope signals.

The Australian plant science community faces a major challenge in being able to comprehensively characterise the performance or phenotype of plants in a high throughput manner necessary for post-genomic era science with model plant species, smart-breeding of crop plants and to assess plant-environment interactions. Our capacity to accurately 'phenotype' either a new mutant or a new variety has fallen behind out capacity to generate novel genetic material. This facility will significantly boost research outputs across a range of disciplines pivotal to Australia's future agricultural plant productivity and environmental sustainability. Read moreRead less
