Professor Elizabeth Aitken (Liz) obtained her BSc Hons in Agricultural Science (Crop Science) from Edinburgh University where she specialised in Plant Pathology. She then went on to undertake her PhD studies at Aberdeen University in conjunction with the UK Forestry Commission on a study of dieback on Scots pine trees. This was followed with postdoctoral studies at Birmingham University and the Sainsbury Lab, aiming to identify a rust resistance gene by transposon tagging. In 1993 she moved to Australia and joined UQ as an academic staff member.

Much of Liz’s research at UQ has focused on diseases of tropical crops in particular banana, ginger, cotton and sunflower. Research topics have included the genetics of plant-pathogen interactions, molecular aspects of pathogenicity and disease diagnostics. This research has been undertaken with strong collaborations with the Queensland Department of Primary Industries and with CSIRO. Research topics have included the genetics of plant-pathogen interactions, molecular aspects of pathogenicity and disease diagnostics. This work has assisted in the identification of disease incursions in particular in banana and of cryptic plant pathogen species of Pythium in ginger and Phomopsis in sunflower. One current research focus includes identification of resistance to Fusarium wilt in diploid banana lines for potential deployment against TR4 in commercial banana cultivars; this has received funding from BMGF in collaboration with the International Institute of Topical Agriculture in Africa as well as from Hort Innovation Australia. Other studies include analysis of putative pathogenicity genes including Six genes in Fusarium oxysporum affecting banana, strawberry and ginger and in collaboration with colleagues at CSIRO studies on Fusarium spp on wheat particularly with regard to influence of environmental factors related to climate change.

Since commencing at UQ in 1993, Liz has supervised numerous postgraduate and honours students and participated in undergraduate teaching at all levels in plant science and in particular in plant pathology and fungal biology. She has also taken on various roles and committee membership in postgraduate student mentoring, research integrity and biosafety.

My research team in crop protection is studying the biology, epidemiology and ecology of economically significant diseases and insect pests. The overarching objective of the research is to facilitate innovative and sustainable management of crop pests (insects and diseases) using disruptive new tools that can be incorporated with the less harmful existing control options in diverse farming systems.

In my PhD I analysed and modelled biophysical processes (light interception, transpiration and photosynthesis) and their relationships in apple and pear trees during the growing season and at different levels of plant water status. During this time I collaborated in the upgrade of a functional-structural peach model (L-PEACH). Later I focused my research on the effect of carbohydrates on grapevine and berry growth, as well as the effects of light, temperature and VPD on carbon assimilation and transpiration both at leaf and canopy level.

Currently, I am undertaking research on improving management practices in avocado, macadamia and mango. I am focused on studying architecture, vegetative vigour, crop load and light interception using functional-structural plant modelling to understand the interactions between management practices, environmental factors, plant carbon balance and growth.

Dr Botella's research interests are in genetic engineering, molecular biology and signal transduction in plants.

Dr. Jimmy Botella is Professor of Plant Biotechnology at the University of Queensland. He obtained a degree in Quantum Chemistry from the University of Madrid (Spain) and a PhD in Biochemistry from the University of Malaga (Spain). After postdoctoral positions at Michigan State University and Pennsylvania State University he joined the University of Queensland in 1995. At UQ he founded the Plant Genetic Engineering Laboratory (PGEL) specialising in the fields of tropical and subtropical agricultural biotechnology for almost 15 years. J. Botella has eleven international patents in the field of Plant Biotechnology and is a founding member of two biotechnology companies (Coridon Ltd. and Origo Biotech).

Dr Botella is a member of the Plant Molecular Biology and Biotechnology research group.

Some highlights of the Plant Genetic Engineering Laboratory’s research:

• Production and field trial of the world’s first genetically modified pineapples with genetic constructs to control flowering time. These pineapples will allow farmer control over harvesting times.
• Development of a new technology to confer protection against nematode infestation.
• Discovery of a gene that can confer resistance to the devastating fungus Fusarium oxysporum in plants.
• Development of a new technology to confer protection against pathogenic fungi in plants.

Research interests

Dr. Botella’s research has two major foci: basic cell biology and applied biotechnology. In cell biology he is interested in studying the function of the Heterotrimeric G proteins in plants. This family of proteins is extremely important in humans but their role in pant systems is still largely unknown. Dr. Botella’s research has strongly contributed to the current body of knowledge available in plants with critical contributions such as the discovery and characterization of the first plant gamma subunits and the establishment of these subunits as the critical element conferring function specificity to all plant G proteins. Dr. Botella’s team has also discovered the important role that these proteins play in defense against pathogens. New and unpublished data has now revealed that G proteins are important yield enhancing factors in crops such as rice. Another research interest resides in the communication between plants and insects. There is plenty of knowledge of how important smell, volatiles emitted by the plant, is for foraging insects in order to determine their host preferences. Nevertheless, most of the available studies have been performed using synthetic chemicals in artificial experimental settings. Dr. Botella’s team and collaborators have genetically engineered plants to produce different volatile mixes in the flowers in order to perform in vivo behavioral studies in insects.

Biotechnology research at the Plant Genetic Engineering Laboratory mostly arises from discoveries made in basic research. The PGEL focuses in tropical and subtropical crops. These crops have attracted little attention in terms of biotechnology but are essential sources of food and energy for a large part of the world’s population, especially in Asia and the Indian subcontinent. The PGEL has developed a number of platform technologies that can be applied to multiple crops in order to confer resistance to pathogens, modify plant architecture and control flowering time.

Current research projects include:

• Plant heterotrimeric G proteins: New roles in defence, stomatal control and ABA perception.
• Putting smells into context: using in vivo technologies to understand plant-insect odour communication.
• Use of host-derived RNA interference technology to control plant pathogens (especially pathogenic fungi and nematodes).
• Control of Fusarium wilt disease.
• Genetic improvement of grain crops.
• Genetic engineering research projects

Summary of Research:

• My current research at UQ is as Professor in this School (teaching AGRC3040 Crop Physiology) and as an Affiliate Professor of QAAFI. Since 2020, with full-time appointment at UQ, my research portfolio has included multiple projects in applications of machine learning and artificial intelligence into the ag domain. This area is developing rapidly and across UQ, I am engaging with faculty in multiple schools (ITEE, Maths and Physics, Mining and Mech Engineering) as well as in the Research Computing Centre to develop new projects and training opportunities at the interface of field agriculture and these new digital analytics.
• My career research has been around genetic and environment effects on physiology of field crops, particularly where drought dominates. Application of quantitative approaches (crop simulation and statistical methods) and phenotyping (aerial imaging, canopy monitoring) to integrate the understanding of interactions of genetics, growth and development and the bio-physical environment on crop yield. In recent years, this work has expanded more generally into various applications in digital agriculture from work on canopy temperature sensing for irrigation decisions (CSIRO Entrepreneurship Award 2022) through to applications of deep-learning to imagery to assist breeding programs.
• Much of this research was undertaken with CSIRO since 1996. Building on an almost continuous collaboration with UQ over that time, including as an Adjunct Professor to QAAFI, Prof Chapman was jointly appointed (50%) as a Professor in Crop Physiology in the UQ School of Agriculture and Food Sciences from 2017 to 2020, and at 100% with UQ from Sep 2020. He has led numerous research projects that impact local and global public and private breeding programs in wheat, sorghum, sunflower and sugarcane; led a national research program on research in ‘Climate-Ready Cereals’ in the early 2010s; and was one of the first researchers to deploy UAV technologies to monitor plant breeding programs.

I obtained my PhD from The Australian National University in 2001 and have been at UQ since August 2006

My research is primarily aimed at understanding the origins, diversification and distributions of organisms, especially plants and insects in Australia. I mostly take a comparative approach and use molecular phylogenies to test hypotheses about ecological and evolutionary processes. Recent and ongoing topics include: understanding how interactions among plants and insects affect the evolutionary radiation of each; teasing apart the effects of extinction and speciation to understand how past climate and environmental change has shaped our biota; and investigating the relative roles of continental drift and long distance dispersal in explaining the current distribution patterns of organisms in the southern hemisphere. Specific questions relate, but are not limited, to topics such as:

• how the diversification of the unique Australian flora has driven insect speciation

• whether specific insect-plant interactions are the result of long term co-radiation or more recent adaptive radiations of insects

• the relative roles of vicariance (such as that induced by continental drift) and dispersal in explaining the current distribution patterns of southern hemisphere organisms

• evolutionary patterns of host-use by herbivores

• how past climate change has shaped the current distributions of taxa

• assembly of the flora and fauna of current biomes, especially the arid zone, monsoon tropics and southern temperate biomes

• phylogeography of plants and insects, and what this reveals about contemporary and recent gene flow

• consequences of differential dispersal, such as that between male and female scale insects, different developmental stages, or seed and pollen

Dr Peter Crisp is an expert in crop genomics, epigenomics and molecular genetics. He leads a research group in the School of Agriculture and Food Science. His research group seeks to understand the contribution of epigenetics to heritable phenotypic variation in crop plants, focusing on cereals including barley, sorghum, wheat and maize. This includes the development of methods to harness epigenetic variation for crop improvement; understanding the role of epigenetics in stress responses and using innovative epigenomic approaches to distill large genomes down to the relatively small fraction of regions that are functionally important for trait variation. Research in the Crisp Lab spans both wet lab and computational biology providing a powerful platform to integrate genetic, genomic and biotechnological approaches.

Paul Dennis leads an exciting research group that applies cutting-edge technologies to understand the roles of microorganisms and their responses to environmental change.

He is also a passionate educator and public speaker who advocates for the importance of biological diversity and evidence-based environmental awareness. He has talked about his research on ABC Radio and a range of other media outlets.

His teaching covers aspects of ecology, microbiology, plant and soil science, and climatology. He considers these topics to be of fundamental importance for the development of more sustainable societies and takes pride in helping others to obtain the knowledge and skills they need to build a better future.

Paul's research has taken him to Antarctica, the Amazon Rainforest, high mountains and oceans. The approaches used in his lab draw on a wide range of expertise in molecular biology, ecology, statistics, computer science, advanced imaging and soil science. He applies these skills to a wide-range of topics and systems including plant-microbe interactions, Antarctic marine and terrestrial ecology, biogeography, pollution and human health.

Plants, unlike animals, are amazingly plastic, having the ability to drastically change their above and below ground architecture in response to changing conditions. These changes in conditions, which may only be local to a specific plant part, can be communicated throughout the plant via long distance signals, including plant hormones, to elicit a plant-wide coordinated response. My research is concerned with the regulation of the above ground shoot architecture, or branching, and how different signals interact to control when, where and how a tiny bud will grow into a branch. This is an important plant trait, being a major determinant of yield in field, horticulture and forestry crops.

The interplay of multiple factors (including hormonal, developmental and environmental) coordinately act to regulate bud outgrowth. The plant hormones strigolactone and auxin inhibit bud outgrowth, while cytokinin promotes outgrowth. Environmental and developmental factors (i.e. photoperiod/daylength, position of axillary bud along stem) and many flowering genes also influence bud outgrowth, particularly the patterns of outgrowth. For example, photoperiod substantially affects the position of branches along the stem, even in decapitated and strigolactone-deficient plants, and therefore does not require the branching hormone strigolactone. Photoperiod regulation of branching patterns is not solely attributable to the process of flowering, as some mutants that do not flower under any photoperiod still display photoperiod-responsive vegetative traits.

My research, using the model plant garden pea (Pisum sativum), seeks to discover how strigolactones and other known hormones/signals regulate shoot architecture in response to environmental factors (photoperiod) and in coordination with developmental processes (flowering). I am studying the interactions between pathways controlling photoperiod, light response, flowering and branching which will help me to identify factors that determine position of branches along the stem. Understanding such crosstalk is important and will be an important step towards targeted modification of plant architecture, enabling bud outgrowth to be directed to desired regions or stages of plant growth.

Most of my research is quantitative field ecology in the big natural playground of Queensland. I do ecology because I want to help avoid extinction and better manage Australia’s natural resources, and also because discovery is extremely enjoyable. In 2010 I am working with co-workers on editing of Ludwig Leichhardt’s diaries, woody vegetation dynamics, artesian desert springs, grazing dynamics in the arid zone, the role of fire in savannas and establishing a large project to facilitate ecosystem restoration within an emerging carbon economy. I have far more ideas than capacity to fulfil them, so welcome committed post-grads to discuss potential projects.

Research themes:

Artesian springs

Artesian springs are isolated oases in a sea of arid-lands containing weird and wonderful endemic creatures including snails, crustacea, plants and fish. The springs provide a focus for research relating to their hydrological function, conservation, optimum management and biogeographic history.

Woody vegetation dynamics

The processes that drive changes in woody plant abundance, including drought-induced dieback, fire, woody plant expansion, aka woody thickening, invasive scrub, woody plant encroachment have been a focus of attention. The issue has been addressed through systematic survey, field and nursery experiments, physiological studies and with systematic use of the historic record, including aerial photography, old survey charts and explorers notes.

Arid-zone grazing

A review of water-remote grazing effects prompted a program of work that will utilise long–term grazing exclosures, water-remote gradients and the ecology of rare plants to build a deeper understanding of grazing in arid landscapes.

Integrating the carbon economy into conservation

This arena provides a broad scope to examine the dynamics of carbon in terrestrial ecosystems, extend our understanding of biodiversity in Australia, and to understand the trade-offs between managing for carbon and for biodiversity

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.
