Summary
Pushing the limits of fluorescence microscopy with adaptive optics. This project aims to establish an adaptive optics, super-resolution optical microscopy facility to image cellular events with the highest possible spatial resolution, in a whole cell or tissue context. Sophisticated computer-controlled deformable mirrors will be used to correct the way light is distorted as it passes through specimens, thereby overcoming aberrations found in thick and complex samples. This adaptive optics system ....Pushing the limits of fluorescence microscopy with adaptive optics. This project aims to establish an adaptive optics, super-resolution optical microscopy facility to image cellular events with the highest possible spatial resolution, in a whole cell or tissue context. Sophisticated computer-controlled deformable mirrors will be used to correct the way light is distorted as it passes through specimens, thereby overcoming aberrations found in thick and complex samples. This adaptive optics system will enable researchers to study complex behaviour of biological specimens, at the optical resolution limit in plant and animal tissues, leading to basic biology and biotechnology outcomes in biofuels, biomaterials and biomedicines.Read moreRead less
Identifying novel salinity tolerance mechanisms by spatial and temporal analysis of lipids in barley. Agrifood production faces the dual challenges of an increasing world population and the threats of abiotic stresses arising from climate change and the erosion of arable land. Cereals, the major food crops, are poorly adapted to tolerate most abiotic stresses, including salinity. This project applies new technologies investigating spatial and temporal biochemical mechanisms a model cereal, Horde ....Identifying novel salinity tolerance mechanisms by spatial and temporal analysis of lipids in barley. Agrifood production faces the dual challenges of an increasing world population and the threats of abiotic stresses arising from climate change and the erosion of arable land. Cereals, the major food crops, are poorly adapted to tolerate most abiotic stresses, including salinity. This project applies new technologies investigating spatial and temporal biochemical mechanisms a model cereal, Hordeum vulgare (barley), utilises to adapt and tolerate salinity. The aims are to investigate the role of specifically plasma membrane lipids modulating either signalling pathways or membrane fluidity that impacts on adaptation during salinity. The results will provide new leads for the development of cereal germplasm with increased salt tolerance.Read moreRead less

Summary
Understanding how water-transporting vessels in plants are made. This project aims to understand how cytoskeleton-associated proteins underpin the formation of water-conducting vessels. Uncovering molecular mechanisms that lead to efficient water transport in plants opens up new avenues to address food and crop safety, particularly in times of environmental change.
ARC Centre of Excellence in Plant Cell Wall Biology. The ARC Centre for Plant Cell Wall Biology will define the regulatory mechanisms that control molecular, enzymic and cellular processes involved in the synthesis, deposition, re-modelling and depolymerisation of cell wall polysaccharides of cereals and grasses. Plant cell walls represent the world's largest renewable carbon resource, but the regulatory mechanisms responsible for their synthesis and assembly are not understood.

The ARC Centre for Plant Cell Wall Biology will define the regulatory mechanisms that control molecular, enzymic and cellular processes involved in the synthesis, deposition, re-modelling and depolymerisation of cell wall polysaccharides of cereals and grasses. Plant cell walls represent the world's largest renewable carbon resource, but the regulatory mechanisms responsible for their synthesis and assembly are not understood. Key distinguishing features of the Centre will be the international, integrative, and multidisciplinary approach towards addressing major questions in plant biology, its strategy to leverage ARC funding, and its linkages with potential national and international end-users of the fundamental scientific discoveries.Read moreRead less
Molecular and cellular mechanisms of action of novel plant guanylyl cyclase enzymes - a new class of overlapping dual-domain molecules. A group of highly unusual catalytic molecules in plants has been identified. The mechanisms of action of these molecules will be studied in this project to learn their role in regulating plant growth in changing climates. The results will reveal how these molecules function and also provide new insights for the development of multi-functional artificial molecule ....Molecular and cellular mechanisms of action of novel plant guanylyl cyclase enzymes - a new class of overlapping dual-domain molecules.

ARC Centre of Excellence in Plant Energy Biology. We propose a novel approach to improve sustainable yield by optimising the overall efficiency of energy capture, conversion and use by plants. Efficiency gains in metabolism, transport, and development will be more effective than optimising single nutrient inputs or product outputs. Improving multiple parameters simultaneously is a necessary solution to the increasing demand for more crop yield from finite land, water, and nutrient resources.

We propose a novel approach to improve sustainable yield by optimising the overall efficiency of energy capture, conversion and use by plants. Efficiency gains in metabolism, transport, and development will be more effective than optimising single nutrient inputs or product outputs. Improving multiple parameters simultaneously is a necessary solution to the increasing demand for more crop yield from finite land, water, and nutrient resources. Unpredictable environmental challenges adversely affect plant growth and further perturb plant energy balance, limiting yield. The epigenetic controls, gene variants and signals discovered will provide a new basis for sustainable productivity of crops and will future-proof plants in changing climates.Read moreRead less
Characterisation of Bioadhesives from Marine diatoms. Biofouling occurs at great expense to governments and industry, adding up to 60% annually to the cost of propulsive fuel consumption in shipping. Diatoms include the most common algal biofoulers of natural and artificial surfaces (e.g. ship hulls). The structure of diatom adhesives will be elucidated in order to determine the molecular basis of their adhesive properties. As diatoms are capable of reversible adhesion, an understanding of th ....Characterisation of Bioadhesives from Marine diatoms. Biofouling occurs at great expense to governments and industry, adding up to 60% annually to the cost of propulsive fuel consumption in shipping. Diatoms include the most common algal biofoulers of natural and artificial surfaces (e.g. ship hulls). The structure of diatom adhesives will be elucidated in order to determine the molecular basis of their adhesive properties. As diatoms are capable of reversible adhesion, an understanding of this mechanism may enable development of strategies to counter adhesion in antifouling products (e.g. paints). This knowledge will contribute to development of new adhesives or strategies to modify and/or prevent adhesion.Read moreRead less
The role of the ammonium transport bHLHm1/AMF1 regulatory loci in plants. This project aims to investigate the role of a regulatory locus in the regulation of ammonium transport in plants and the interacting genetic and biochemical signalling promoting the interaction. Ammonium is an important nutrient source for plant growth and development.

This project aims to investigate the role of a regulatory locus in the regulation of ammonium transport in plants and the interacting genetic and biochemical signalling promoting the interaction. Ammonium is an important nutrient source for plant growth and development. It has been recently identified that a new transport mechanism (AMF1 ) mediates ammonium transport across legume root nodule cellular membranes. AMF1 was identified through a transcriptional interaction with a membrane localised bHLHm1 transcription factor. Both bHLHm1 and AMF1 belong to a unique chromosomal regulatory locus common across sequenced dicot plant species.Read moreRead less
Novel methods for the production of micronutrient-enriched rice. The increasingly productive Australian rice industry generated AUD$1 billion revenue in 2012. By targeting a rice gene that we recently identified as a key regulator of iron uptake and transport, this project will produce high value, micronutrient-enriched rice grain to improve the nutritional health of people in Australia and throughout the world.
Can we engineer plants to grow on salty soils? This project aims to answer questions about how plants can sustain their growth on salty soils. Plant-derived products constitute a pillar for our society. However, crop yields may be severely penalised due to unfavourable growth conditions, including soil salinity. This is particularly relevant for Australia as a large fraction of its arable land is affected by salt. This project aims to use molecular and cell biology techniques to resolve mechanis ....Can we engineer plants to grow on salty soils? This project aims to answer questions about how plants can sustain their growth on salty soils. Plant-derived products constitute a pillar for our society. However, crop yields may be severely penalised due to unfavourable growth conditions, including soil salinity. This is particularly relevant for Australia as a large fraction of its arable land is affected by salt. This project aims to use molecular and cell biology techniques to resolve mechanisms of how the synthesis of cellulose, which constitutes the bulk of a plant's biomass, is maintained in plants during salt stress. This project has potential for climate change mitigation, enhanced plant biomass production and improved fuel security.Read moreRead less
