This project aims to improve the efficiency of advanced single-celled green algae (microalgae) production systems which can produce a wide range of high-value products including renewable fuels and animal feeds. Such systems are able to expand photosynthetic capacity onto non-arable land using carbon dioxide and saline water. However, production efficiencies and costs are currently limited by the ability to capture and distribute light through these systems effectively. This project aims to optimise methods of light delivery and distribution through photo-bioreactors and high rate ponds. This knowledge is intended to be integrated into advanced modelling tools to enable model-guided design of next-generation high-efficiency systems.Read moreRead less
Solving smoke taint: Overcoming the impacts of vineyard exposure to smoke. Vineyard exposure to bushfire smoke can taint grapes, causing significant revenue losses where smoky, ashy characters render wine unsaleable. Smoke taint therefore remains an ongoing threat to the viability of the wine industry. This project aims to safeguard grape and wine quality by building the wine industry’s capacity to predict, mitigate and respond to risk associated with vineyard smoke exposure. Expected outcomes i ....Solving smoke taint: Overcoming the impacts of vineyard exposure to smoke. Vineyard exposure to bushfire smoke can taint grapes, causing significant revenue losses where smoky, ashy characters render wine unsaleable. Smoke taint therefore remains an ongoing threat to the viability of the wine industry. This project aims to safeguard grape and wine quality by building the wine industry’s capacity to predict, mitigate and respond to risk associated with vineyard smoke exposure. Expected outcomes include establishing the mechanism by which smoke compounds are taken up by grapes and the factors that influence their sensory impact on wine. The development of innovative and interdisciplinary strategies for detecting and alleviating smoke taint will deliver important economic benefit to the Australian wine sector.Read moreRead less
Genomic basis of clonal variation in Cabernet Sauvignon wine grapes. The commercial practice of vegetative propagation results in novel clones through discrete mutations, creating challenges for horticultural and wine industries. This project will use cutting edge molecular profiling to design methods to map the identity of grapevines in whole vineyards, enabling industry to capture this variation for crop improvement.
How to make antibiotics in pig feed redundant, naturally. Antimicrobial resistance has become a major issue in human and veterinary medicine being partially caused by the use of in-feed antimicrobials in farm animals. This project aims to completely eliminate antimicrobials from piglet feeds. The key differential approach is based on helping the physiology of the animal rather than testing interventions against bacteria. The project will consist of developing a novel nutritional strategy of natu ....How to make antibiotics in pig feed redundant, naturally. Antimicrobial resistance has become a major issue in human and veterinary medicine being partially caused by the use of in-feed antimicrobials in farm animals. This project aims to completely eliminate antimicrobials from piglet feeds. The key differential approach is based on helping the physiology of the animal rather than testing interventions against bacteria. The project will consist of developing a novel nutritional strategy of naturally (through maternal conditioning) boosting the natural appetite and the capacity to digest in piglets early in life. The anticipated outcome is that the new peri-natal program will result in minimal bacterial proliferation and diarrhoea thus, negating the need for in-feed antimicrobials in piglets.

Aquaporins in roots: resolving observations linking them to diverse processes in water relations and plant productivity. The knowledge we gain will benefit Australia by allowing better management of plant water use and productivity. This is critical for adaptation to a drier climate where water is a critical resource. Large quantities of water move through aquaporin proteins in plants, therefore our understanding of these and the way they influence other processes in plant growth could enable us ....Aquaporins in roots: resolving observations linking them to diverse processes in water relations and plant productivity. The knowledge we gain will benefit Australia by allowing better management of plant water use and productivity. This is critical for adaptation to a drier climate where water is a critical resource. Large quantities of water move through aquaporin proteins in plants, therefore our understanding of these and the way they influence other processes in plant growth could enable us to manipulate plants to conserve water or to extract it more efficiently from the soil. Molecular aspects of the project could reveal new unexploited links between water and plant productivity. High calibre PhD and Honours students will also be educated to maintain the momentum of international excellence within Australia in the field of plant water relations.Read moreRead less
Understanding, controlling and improving the flavour of almond kernels. Almond kernels may be sweet, semi-bitter or bitter, with the first two categories marketed as fresh nuts, while the latter are used in processed products such as marzipan. Semi-bitter kernels have a more interesting flavour than sweet kernels and we require tools to breed for this character. The bitter flavour is imparted by amygdalin via the cyanogenic pathway. This project will characterise the genetic control of sweet, ....Understanding, controlling and improving the flavour of almond kernels. Almond kernels may be sweet, semi-bitter or bitter, with the first two categories marketed as fresh nuts, while the latter are used in processed products such as marzipan. Semi-bitter kernels have a more interesting flavour than sweet kernels and we require tools to breed for this character. The bitter flavour is imparted by amygdalin via the cyanogenic pathway. This project will characterise the genetic control of sweet, semi-bitter and bitter flavour, amygdalin accumulation in developing kernels, and key enzymes in the cyanogenic pathway. Almond populations segregating for these traits will be used and the data will be integrated into the Australian almond meiotic map.Read moreRead less
Microsatellite marker development for almond breeding. Australian almond growers produce 8,000 tonnes of kernel annually, and the long term aim is to develop strong export markets. The industry funds a breeding program at Adelaide University, comprising hybridisation and selection. Through our current ARC SPIRT grant we augment this with a program in molecular techniques. Research is well-advanced in the development of a genetic map for almond based on both molecular and agronomic characters. ....Microsatellite marker development for almond breeding.

The main objective of this project is to identify drought and nutrient-deficiency responsive pathways in tolerant wheat and to provide markers to breeding programs that facilitate selection of superior breeding lines. This project builds on a pilot study conducted in rice in which tolerant-specific metabolites were identified which are representative of pathways relevant for the protection of cells from damage through reactive oxygen species (ROS) and for nutrient (nitrogen, phosphorus, sugars) recycling under stress. Available data suggest that these pathways are also relevant in wheat. Quantitative metabolomics, genetics, and molecular tools will be used to deliver either DNA-based or metabolomics markers to breeders.Read moreRead less
