The Australian Research Data Commons (ARDC) invites you to participate in a short survey about your
interaction with the ARDC and use of our national research infrastructure and services. The survey will take
approximately 5 minutes and is anonymous. It’s open to anyone who uses our digital research infrastructure
services including Reasearch Link Australia.
We will use the information you provide to improve the national research infrastructure and services we
deliver and to report on user satisfaction to the Australian Government’s National Collaborative Research
Infrastructure Strategy (NCRIS) program.
Please take a few minutes to provide your input. The survey closes COB Friday 29 May 2026.

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
Mediator: a new concept for controlled gene expression in plant biotechnology. The Mediator protein complex is a new control point for the activation of all genes in higher organisms and the purpose of this project is to understand how three Mediator subunits regulate disease resistance in plants. The outcomes provide a new concept to direct natural gene expression towards robust crop plants able to cope with climatic variations.

Summary
Spectral climate chamber facilities for phenomic studies of plant light response adaptation. Climates are changing, altering planting regimes in agriculture, and disrupting local adaptation in foundation species. The genetic basis of climate adaptation will be dissected in new plant growth facilities, equipped with real-time imaging and environmental controls that can mimic dynamic seasonal growing conditions and weather stress events.
Tolerance of temperature extremes under drought: linking physiological processes with morphological constraints on leaf function. Freezing temperatures affect over 70% of Australia. Each year frosts cause substantial damage to agriculture and forestry. We will examine how decrease in hydraulic conduit diameter increases freeze tolerance in native woody species and quantify impacts of this tolerance on productivity of leaves. The results have application in managing temperate woody vegetation un ....Tolerance of temperature extremes under drought: linking physiological processes with morphological constraints on leaf function. Freezing temperatures affect over 70% of Australia. Each year frosts cause substantial damage to agriculture and forestry. We will examine how decrease in hydraulic conduit diameter increases freeze tolerance in native woody species and quantify impacts of this tolerance on productivity of leaves. The results have application in managing temperate woody vegetation under current and future climate scenarios. By improving understanding of the behaviour of water in leaves during freezing, we will contribute to improved models of physical stresses and strains in biological tissues during freezing, which find application in cryo-storage of biological materials important in agriculture, medicine, and conservation.Read moreRead less
