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.

What is the function of gamma-aminobutyric acid-gated anion channels in plants? The project will identify the molecular basis of gamma-aminobutyric acid (GABA) signalling in plants. This is significant because GABA regulates proteins that release molecules involved in root-soil interactions, growth, and fertilisation. The project's discoveries will allow improvement of these agronomic traits that ultimately determine crop yield.
Functional network analysis of plant metabolism in response to salinity and temperature through targeted proteomics. This project will measure changes in plant metabolism and provide methods and a pipeline for quantification and modelling. It will assess nitrogen linked metabolism under environmental stress experienced in Australian wheat cropping systems and build fundamental knowledge of changes in networks of nitrogen metabolism in model plants.

Summary
New facilities for multiplex gas-exchange (MGX) measurements of plant performance during climate-controlled growth. Precise study of oxygen and carbon dioxide gas exchange can quantify the underlying factors responsible for plant growth. This dedicated facility will increase the scope and accuracy of Australian research into plant productivity thereby allowing improved understanding of factors affecting plants' adaptability to environmental change and plant competition or pathogen effects.

Dynamic Proteins for Nutritious Future Crops. This project aims to understand the processes and genes that regulate synthesis and degradation of proteins in wheat and barley plants. This project will develop methodologies and a new field of research for optimising protein stability in crops. Its significance lies in defining new ways to control protein abundance to increase crop performance and quality and increase the value of recombinant proteins for biotech industries. Expected outcomes will ....Dynamic Proteins for Nutritious Future Crops. This project aims to understand the processes and genes that regulate synthesis and degradation of proteins in wheat and barley plants. This project will develop methodologies and a new field of research for optimising protein stability in crops. Its significance lies in defining new ways to control protein abundance to increase crop performance and quality and increase the value of recombinant proteins for biotech industries. Expected outcomes will enable the protein abundance in plant cells to be designed and control selective protein degradation in plants for the first time. Benefits will include building biotechnology capacity in WA, brokering new collaborations and providing an ideal training environment for students and postdocs.Read moreRead less
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. Unp ....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. 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
A novel role for phytochrome in dormancy release inhibition. Seed dormancy contributes to the persistence of weeds in agriculture by enabling seeds to remain viable in the soil for many years, and is a major reason why annual ryegrass (Lolium rigidum) has become the most economically damaging weed in Australian agriculture. Recently we discovered a new way to control dormancy release and germination in these seeds. This project to identify the changes occurring within the seeds during dormancy r ....A novel role for phytochrome in dormancy release inhibition.

Recently we discovered a new way to control dormancy release and germination in these seeds. This project to identify the changes occurring within the seeds during dormancy release will underpin our efforts to manipulate emergence timing in order to improve the efficacy of current weed control practices and contribute to sustainable farming systems.Read moreRead less
Molecular mechanisms governing the role of calcium in aluminium toxicity and tolerance in plants. Aluminium is the most important yield-limiting factor in acid soils throughout the world. The problem of aluminium toxicity is aggravated by continuous acidification of arable land. Mechanisms of aluminium toxicity in plant cells are poorly understood. The present project seeks to elucidate the molecular basis of the interaction between intracellular calcium homeostasis and plasma membrane potential ....Molecular mechanisms governing the role of calcium in aluminium toxicity and tolerance in plants. Aluminium is the most important yield-limiting factor in acid soils throughout the world. The problem of aluminium toxicity is aggravated by continuous acidification of arable land. Mechanisms of aluminium toxicity in plant cells are poorly understood. The present project seeks to elucidate the molecular basis of the interaction between intracellular calcium homeostasis and plasma membrane potential in aluminium toxicity to plants. Knowledge of primary triggers of aluminium toxicity will pay off in a breeding programme aimed at selecting crop genotypes with increased resistance to aluminium toxicity.Read moreRead less

Summary
Terabase sequencing for mutant, developmental, environmental and population genomics. This facility will make it possible to completely sequence the genome (and epi-genome and transcriptome) of a large number of samples in a cost effective manner. This will provide researchers with unprecedented ability to compare individuals in a population and to discover and define novel traits which govern disease resistance, yield and population dynamics in natural systems.

This project will explore the genetic and molecular mechanisms underpinning pre-harvest sprouting (PHS) and late-maturity amylase (LMA). This project will apply transcriptomics and proteomics to measure the expression of the biomolecules associated with PHS and LMA, generating fundamental knowledge of grain molecular physiology that addresses a significant knowledge gap. The project will deliver tools capable of differentiating these conditions, thereby minimising economic losses. A better understanding of the genetic basis of PHS and LMA will lay the foundation for advanced breeding aiming to eliminate these. Read moreRead less
