Genetics of mental health (new research)

We are using the genetic model organism, C. elegans, do investigate the genetic basis of both normal and disordered behaviour. Our current interests are identifying the genes responsible for anxiety and depression as well as the genes for eating disoders and addiction. Using C. elegans as a model organism will also allow us to study gene function as it relates to behaviour.

Molecular mechanisms of phosphine resistance (other research)

Genetic mapping of oxidative stress resistance genes. The fumigant phosphine disrupts oxidative metabolism, resulting in the production of reactive oxygen intermediates. This causes the premature ageing and death of targeted pests. Insect pests of stored grain in Australia now exhibit resistance to phosphine at levels more than 200 times the normal lethal dose.

We have genetically mappedf and identified the genes responsible for phosphine resistance in tall major insect pests of stored grain. We are using a systems biology approach in the model organism C. elegans to understand the molecular basis of phosphine action. Our genetic studies have recently shown that resistance to phosphine is associated with an extension of lifespan

I am an entomologist with a research interest focused on studying host-pathogen interactions and discovering insect-specific viruses. I have investigated gene expression and the role of small non-coding RNAs in various host-pathogen models, particularly in crucial agricultural pests and medically significant vectors like the Aedes aegypti, responsible for transmitting dengue and Zika viruses. My previous project, aimed at exploring the function of Oryctes rhinoceros nudivirus in the biological control of the coconut rhinoceros beetle in the Pacific Islands, has substantially enhanced our comprehension of this invasive pest within the framework of an offshore biosecurity strategy. By establishing industry partnerships and securing funding to improve the Australian sugar industry, one of Australia's largest agricultural sectors, I have been able to focus on entomopathogenic viruses that affect root-feeding pests in sugarcane.

A/Prof Brett Ferguson’s research interest are in molecular genetics, genomics, genetic transformation and genome editing, such as CRISPR, to unravel the molecular mechanisms driving plant development. His primary focus is on legume crops, using biotechnology and bioinformatic approaches to identify key genes and signals controlling traits of interest. This includes the agriculturally- and environmentally-important symbiosis between legume plants and beneficial rhizobia bacteria that fix critical nitrogen for their host plant. In addition, A/Prof Ferguson works with the fascinating legume tree, Pongamia pinatta, which has tremendous potential as a feedstock for the sustainable production of biodiesel and aviation fuel.

A/Prof Brett Ferguson leads the Integrative Legume Research Group (ILRG) in the School of Agriculture and Food Sciences (SAFS) at the University of Queensland (UQ). He is an Affiliate of the Centre for Crop Science in the Queensland Alliance for Agriculture and Food Innovation (QAAFI), and an Affiliate of the ARC Centre of Excellence for Innovations in Peptide and Protein Science (CIPPS). A/Prof Ferguson is also a Chief Investigator in the large, multi-national Hy-Gain for Smallholders Project primarily funded by the Bill & Melinda Gates Foundation.

The work of A/Prof Ferguson has contributed to the discovery of many new genes and signals, such as novel microRNAs and peptide hormones, that have critical roles in controlling plant development. His research group identified the complete family of CLE peptide encoding genes of several legume species using an array of molecular and bioinformatic approaches. Additional discoveries of genes involved in legume nodule formation, nitrogen signalling and the regulation of root development, are also having an impact in the research field. Many of these factors could be useful in supporting translational studies and breeding programs that look to improve crop performance. His work also established a requirement for brassinosteroid hormones in legume nodulation and demonstrated a central role for gibberellins in nodule development. Moreover, he contributed to some of the initial work reporting a role of strigolatones in shoot branching, and demonstrated that plants can transport quantities of auxin far in excess of their endogenous levels.

A/Prof Ferguson has also contributed to the developed of new tools and techniques, such as petiole feeding, precision feeding in growth pouches, stem girdling, pHairyRed for promoter-reporter fusions, new hairy-root transformation techniques, novel integrative vectors to enhance transformation efficiency, synthetic biology approaches to generate mature double stranded miRNA, etc.

My research focuses on the biological control and integrated management of insect pests. Understanding the ecological and biological relationships between insects and their natural enemies (pathogens, parasitoids and predators) and the interactions between these natural enemies is fundamental to effective biological control and is central to my research. Strategies which manipulate natural enemies to enhance their impact on pest populations are under development, examples include

• Integration of biological stressors and fungal entomopathogens for improved control of insect pests
• Reduced insecticide inputs combined with the provision of adult food sources to enhance endemic parasitoid performance
• Utilizing inducible plant defences to manipulate pests and improve the effectiveness of natural enemies.

Externally funded research projects concentrate on the development of sustainable pest management strategies for insect pests in developing countries. In Indonesia the structure and function of the natural enemy complexes attacking the diamondback moth (Plutella xylostella) and the cabbage cluster caterpillar (Crocidolomia pavonana) are being determined. In Samoa the biology and ecology of the egg parasitoid Trichogramma chilonis is being investigated and the possibility of its release as a biological control agent of C. pavonana in Fiji, Tonga and Solomon Islands explored. Research in Fiji is focused on quantifying field resistance of the diamondback moth to commonly used insecticides. An insecticide resistance management strategy has been developed and will be implemented in collaboration with UN-FAO.

I am a plant pathologist specialising in the study of fungal pathogens of all manner of plants from agricultural and natural settings. My research career has spanned various areas of interest from horticultural and agricultural crop diseases, the development of disease forecasting systems, the study of soil mycorrhizal fungi, the use of beneficial microbes in promoting soil health and plant disease management and the scholarship of teaching and learning.

A key area of development has been the investigation of dieback disorders of invasive woody weeds in the Australian landscape. This has resulted in the development of a bioherbicide for the invasive weed Parkinsonia and the establishment of a start-up company - BioHerbicides Australia (BHA). BHA now produces this bioherbicide (which is a registered product) and has developed a range of synthetic herbicide products along with the delivery technology required for field implementation. My research team bioprospects for new control agents for a range of woody weeds (there are many) and also explores the use of synthetic herbicides. My research takes me to many interesting locations in outback Queensland, the Northern Territory, Western Australia and New South Wales. I am interested in many weed species including mimosa bush, chinee apple, celtis, prickly acacia, athel pine, mesquite, leucaena, rubber vine and various cacti.

Science and technology of ecological engineering of ferrous and base metal mine tailings (e.g., magnetite tailings, bauxite residues (or red mud), Cu/Pb-Zn tailings) into functional technosols and hardpan-based soil systems for sustainable tailings rehabilitation: geo-microbial ecology, mineral bioweathering, geo-rhizosphere biology, technosol-plant relations in mined environments. Championing nature-based solutions to global mine wastes challenges.

Longbin Huang is a full professor and a Program leader in The University of Queensland, leading a research program of "Ecological Engineering in Mining" to develop naure-based methdology and technology, for assisting the world's mining industry to meet the global tailings challenge. Driven by the passion to translate leading knowledge into industry solutions, Longbin has pioneered transformative concepts and approach to tackle rehabilitation of mine wastes (e.g., tailings, acidic and metalliferous waste rocks). Recent success includes the "ecological engineering of Fe-ore tailings and bauxite residue" into soil, for overcoming the topsoil deficit challenge facing the mining industry. Scaled up field trials have been going on to deliver the much-needed technology into field operations. Long-term and multi-site based field trials have demonstrated for the first time, the field-feasibility to accelerate nature-based soil formaiton processes for developing tailings into adaptive and sustainable soil (or technosol) capable of sustaining plant community growth and development (https://www.youtube.com/watch?v=6VzfiWL-8UI&t=4s).

The program consists of a group of researchers with leading knowledge and research skills on: soil/geo-microbial ecology, environmental mineralogy, bioweathering of minerals, native plant rhizosphere (micro)biology, soil-plant relations, and environmental materials (such as biochar and environmental geopolymers). It aims to deliver transformative knowledge and practices (i.e., technologies/methdologies) in the rehabilitation of mine wastes (e.g., tailings, mineral residues, spoils, waste rocks) and mined landscapes for non-polluting and ecologically and financially sustainable outcomes.

In partnership with leading mining companies, Longbin and his team have been focusing on developing game-changing knowledge and technologies of tailings valorisation for achieving non-polluting and ecologically sustainable rehabilitation of, for example, coal mine spoils and tailings, Fe-ore tailings, bauxite residues (or red mud), and Cu/Pb-Zn tailings. Leading the global progress in bauxite rehabilitation, Longbin and his team are currently taking on field-scale research projects on bauxite residue rehabilitation technologies at alumina refineries in Queensland (QAL- and Yarwun refineries) and Northern Territory (Gove refinery).

Longbin's industry-partnered research was recognised in 2019 UQ’s Partners in Research Excellence Award (Resilient Environments) (Rio Tinto and QAL).
