Determining how the soluble dietary fibre beta-glucan is made in cereals. This Project aims to define the molecular mechanisms that control the processes involved in the biosynthesis and regulation of mixed linkage glucan, a major soluble dietary fibre in the cell walls of cereal grains. Plant cell walls determine the quality of most plant-based products used in modern human societies, yet the regulatory mechanisms responsible for their modulation are not well understood.

Plant cell walls determine the quality of most plant-based products used in modern human societies, yet the regulatory mechanisms responsible for their modulation are not well understood. Key distinguishing features of the Project will be the international, integrative, and multidisciplinary approach towards addressing this major challenge in plant biology and the potential of the fundamental scientific discoveries to benefit end-users in the food, feed and beverage industries.Read moreRead less

Molecular basis of synergy between PIs and defensins against fungi. The plant defensin nicotinamide adenine dinucleotide dehydrogenase subunit 1 (NaD1) has potent antifungal activity against agricultural and human pathogens and has potential in the treatment of serious diseases that affect crop production and human health. NaD1 has been found to permeabilise membranes and allows entry of other molecules into the fungal cytoplasm. While screening for molecules that enhance the activity of defensi ....Molecular basis of synergy between PIs and defensins against fungi. The plant defensin nicotinamide adenine dinucleotide dehydrogenase subunit 1 (NaD1) has potent antifungal activity against agricultural and human pathogens and has potential in the treatment of serious diseases that affect crop production and human health. NaD1 has been found to permeabilise membranes and allows entry of other molecules into the fungal cytoplasm. While screening for molecules that enhance the activity of defensins a number of proteinase inhibitors were identified that act synergistically with NaD1. This project aims to identify the molecular basis of this synergy which is expected to lead to better control of fungal diseases of crops and in humans.Read moreRead less

Summary
Melbourne and Monash integrated proteomics facility. This project will provide two Victorian proteomic core facilities with cutting edge technology that will address a major gap in our mass spectrometry and protein interaction capabilitiy. These core facilities support a vast array of basic/applied research that depends on the characterisation of proteins and small molecules at a molecular level.
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.

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
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
New approaches for screening cereal germplasm for enhanced microbial pathogen resistance and desirable grain texture. The trait of grain hardness (texture) is of significance to the Australian infrastructure, as exports of hard wheat contribute over 5 billion dollars per year on average to the national economy and hard wheats are also important for domestic usage. The genes responsible for grain texture also impart resistance to bacterial and fungal pathogens which can cause extensive damage. ....New approaches for screening cereal germplasm for enhanced microbial pathogen resistance and desirable grain texture. The trait of grain hardness (texture) is of significance to the Australian infrastructure, as exports of hard wheat contribute over 5 billion dollars per year on average to the national economy and hard wheats are also important for domestic usage. The genes responsible for grain texture also impart resistance to bacterial and fungal pathogens which can cause extensive damage. However, the Australian gene pool has very limited genetic diversity in grain textures and thus possibly in pathogen resistance. The project will work out the science behind these two traits and identify lines with new variants of textures and pathogen resistances, thus greatly benefiting the national infrastructure and local primary industries.Read moreRead less

This research hub aims to provide Australian growers and industrial stakeholders with improved plant materials to maximise production, environmental sustainability and profitability. In particular, the research aims to improve the nitrogen delivery capacity of legumes and their resilience to abiotic stress, which will be an important consideration as our climate changes. Grain legumes are often grown in rotation with cereal crops for their high nutritional seed value and their unique ability to develop a self-sufficient nitrogen-fixing symbiosis with soil bacteria. Maintaining legume productivity against the challenges of climate change and the need for increased food production is important to the future of Australian agriculture.Read moreRead less

This project aims to generate bread containing high amounts of biologically available iron through targeted manipulation of plant-derived phytonutrients at several points along the wheat-to-bread supply chain. The project expects to generate new knowledge for developing healthier bread and address consumer demands for value-added food products. Anticipated outcomes are novel plant breeding and food manufacturing techniques that enhance the nutritional composition of wheat grain and bread making products, resulting in higher-value agricultural commodities and breads. The project should benefit bread retailers and crop growers involved in Australia’s $4.7 billion bread market and reduce the environmental impacts of bread production.Read moreRead less
