The Australian aquaculture industry has rapidly grown in the past decade producing premium quality, high value species, e.g. tuna and oyster. In the new millennia it is predicted that the Australia aquaculture industry will be the most profitable area within the Australian seafood industry. An integral component for the long-term sustainability of the Australian aquaculture industry is the availability of top-quality microalgal concentrates, shelf-stable pastes or live feeds, which provide the nutritional requirements of aquatic species in the hatcheries. This project will develop novel microalgal production strategies that would add value to the Australian aquaculture industry.Read moreRead less
The Other Side: Long-distance Feedback and Cross-talk in the Arabidopsis Branching Gene Network. Shoot structure in nearly all plants impacts on water relations, yield and sustainability. Isolation of novel genes and plant hormone pathways that affect shoot structure should allow us to capture IP for Australia and enhance plant improvement and sustainability. One of the pathways we will investigate produces glucosinolates, small plant-specific molecules that have considerable value as anti-cance ....The Other Side: Long-distance Feedback and Cross-talk in the Arabidopsis Branching Gene Network. Shoot structure in nearly all plants impacts on water relations, yield and sustainability. Isolation of novel genes and plant hormone pathways that affect shoot structure should allow us to capture IP for Australia and enhance plant improvement and sustainability. One of the pathways we will investigate produces glucosinolates, small plant-specific molecules that have considerable value as anti-cancer agents in humans. Flavonoids, another pathway regulated in our shoot branching lines, also benefit human health. Graduate students and postdoctoral researchers will gain skills in research management, design, ethics and experimental methods pertinent to the growing biotechnology industry in Australia.Read moreRead less
Why are many fungicide lead compounds active against pathogens in axenic culture but inactive when applied to infected plants? It is much cheaper and easier to screen compounds for fungicidal activity in vivo (that is against the fungus grown in axenic culture) than to test in planta. However, it is commonly observed that compounds active in in vivo screens do not subsequently prove to be active in planta. The aim of this project is to investigate the physiological, biochemical and genetics basi ....Why are many fungicide lead compounds active against pathogens in axenic culture but inactive when applied to infected plants? It is much cheaper and easier to screen compounds for fungicidal activity in vivo (that is against the fungus grown in axenic culture) than to test in planta. However, it is commonly observed that compounds active in in vivo screens do not subsequently prove to be active in planta. The aim of this project is to investigate the physiological, biochemical and genetics basis of this discrepancy and to attempt to provide tools that circumvent the problem. It is expected the project will generate novel information on the environment in the plant experienced by the fungus.Read moreRead less

We seek to establish an Australian first confocal laser scanning microscope with time resolved imaging and fluorescence correlation spectroscopy capabilities. Its advantages include ultrasensitive detection of weak fluorescent emissions against high autofluorescent background by using fluorescence lifetime signatures, with over three orders of magnitude discrimination improvement. The system will also be able to monitor binding of single molecules. These techniques will open new and exciting avenues for interdisciplinary research at the frontier between biological and physical sciences. The microscope will operate within an existing multi-user Optical Characterisation Facility supporting research of an established network of scientists in the Sydney area.Read moreRead less

This project will investigate molecular mechanisms of photosynthesis in Chl d with the view to applying our findings in biotechnology and artificial photosynthesis. We will use a variety of molecular biology, proteomics and physical techniques to probe the bonding of Chl d to binding proteins. Synthetic peptide maquettes will provide a model to develop this understanding. Only two chlorophylls (a and d) have so far been found to take part in the primary reactions of photosynthesis. This research will grow our understanding of this pivotal process and underpin future developments in artificial photosynthesis and in the photonics industry.Read moreRead less

Efficient organelle transformation. Chloroplasts and mitochondria are the powerhouses of plant and animal cells. Ability to express introduced genes in these organelles has enormous biotechnological potential in agriculture and medicine, but practical development has been almost stalled for 15 years by very low transformation efficiency. Plastid transformation is today routine only in tobacco; and mitochondrial transformation has been achieved only in yeasts and algae. We have developed a soluti ....Efficient organelle transformation. Chloroplasts and mitochondria are the powerhouses of plant and animal cells. Ability to express introduced genes in these organelles has enormous biotechnological potential in agriculture and medicine, but practical development has been almost stalled for 15 years by very low transformation efficiency. Plastid transformation is today routine only in tobacco; and mitochondrial transformation has been achieved only in yeasts and algae. We have developed a solution, and achieved the key technical requirements for proof of concept. This collaboration between industry, government and university partners will deliver key Australian-owned IP, for environmentally-friendly plant biofactories, and for treatment of mitochondrial genetic disorders.Read moreRead less
Seafood safety: high throughput diagnostics for ciguatoxin risk assessment. This project aims to develop a novel, high throughput platform for rapidly assessing ciguatoxins. Species of the marine microalgae Gambierdiscus produce ciguatoxins, which accumulate in fish through marine food chains to cause the often debilitating human illness called ciguatera fish poisoning. Ciiguatera fish poisoning is a growing and substantial risk for the $2.2 billion Australian commercial fishing industry.

Species of the marine microalgae Gambierdiscus produce ciguatoxins, which accumulate in fish through marine food chains to cause the often debilitating human illness called ciguatera fish poisoning. Ciiguatera fish poisoning is a growing and substantial risk for the $2.2 billion Australian commercial fishing industry. This serious illness is increasingly impacting more southerly areas of Australia due to environmental changes. The outcomes of this project include new knowledge of the risk of ciguatoxins at Australian 'hot spot' sites, extensively field tested methods for detecting Gambierdiscus and ciguatoxins in situ and key data to inform policy to safeguard the seafood industry and consumers.

Cellulose-based composites as models for primary plant cell walls of cereals and grasses. Cereals and grasses are the lynchpins of the Australian Agri-Food industry. Cell walls provide shape, form and barrier properties to the plant and are the basis for both post-harvest mechanical properties and direct nutritional benefits. There is as yet no validated model for the molecular assembly, architecture and mechanical behaviour of cereal/grass cell walls.

Cereals and grasses are the lynchpins of the Australian Agri-Food industry. Cell walls provide shape, form and barrier properties to the plant and are the basis for both post-harvest mechanical properties and direct nutritional benefits. There is as yet no validated model for the molecular assembly, architecture and mechanical behaviour of cereal/grass cell walls. This project aims to derive such a model, so that predictions can be made concerning the effects of tailoring either plant composition (e.g. at the gene level) or post-harvest treatment in order to achieve desired plant or food properties. The findings will also be relevant to understanding how individual features of cell walls affect digestibility and nutritional properties.Read moreRead less
