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.

IMPROVING NITROGEN USE EFFICIENCY IN CROP PLANTS: ROLE OF THE AMMONIUM TRANSPORT FAMILY AMT. Improving nitrogen use efficiency in crop plants will reduce the use of environmentally damaging nitrogen fertilisers that threaten through leaching the sustainability of Australia's agricultural sector and local water ecosystems. Plants contain genes that encode transport proteins required for the uptake of nitrogen (ammonium and nitrate) from the soil. We will identify the in planta activity of the A ....IMPROVING NITROGEN USE EFFICIENCY IN CROP PLANTS: ROLE OF THE AMMONIUM TRANSPORT FAMILY AMT. Improving nitrogen use efficiency in crop plants will reduce the use of environmentally damaging nitrogen fertilisers that threaten through leaching the sustainability of Australia's agricultural sector and local water ecosystems. Plants contain genes that encode transport proteins required for the uptake of nitrogen (ammonium and nitrate) from the soil. We will identify the in planta activity of the AMT family of ammonium transporters and associated signalling pathways which control the uptake and assimilation of ammonium in plants. This project will confirm the mechanisms involved in ammonium uptake from the soil and lead to the development of ammonium-nitrogen efficient crop plants.Read moreRead less
Biofertiliser technology for improved yields and environmental sustainability of rice and wheat crops. Australia faces the double challenge of improving the efficiency of its crop production while minimising the agricultural impact on its fragile biodiversity. Our project will meet this challenge by providing the technology for using natural biofertilisers in cereal crops. This will reduce our heavy reliance on chemical fertilisers - with associated soil loss, salinity and acidity, and high dema ....Biofertiliser technology for improved yields and environmental sustainability of rice and wheat crops. Australia faces the double challenge of improving the efficiency of its crop production while minimising the agricultural impact on its fragile biodiversity. Our project will meet this challenge by providing the technology for using natural biofertilisers in cereal crops. This will reduce our heavy reliance on chemical fertilisers - with associated soil loss, salinity and acidity, and high demand on scarce water resources - and significantly increase our crop yields. Our advances will help Australian farmers to reduce the costs and increase the productivity of our substantial export crops while improving their environmental sustainability.Read moreRead less
FUNCTIONAL GENOMICS OF PLANT MITOCHONDRIA: THEIR ROLE IN DEVELOPMENT, OXIDATIVE STRESS AND PLANT DEFENSE. Crops encounter many situations in their environment which place them under stress. Reactive oxygen molecules produced in these situations act as messengers to trigger defence mechanisms but also cause cellular damage. Mitochondria are the subcellular compartments involved in energy production and are essential for plant development and growth. However, they also have been implicated in th ....FUNCTIONAL GENOMICS OF PLANT MITOCHONDRIA: THEIR ROLE IN DEVELOPMENT, OXIDATIVE STRESS AND PLANT DEFENSE. Crops encounter many situations in their environment which place them under stress. Reactive oxygen molecules produced in these situations act as messengers to trigger defence mechanisms but also cause cellular damage. Mitochondria are the subcellular compartments involved in energy production and are essential for plant development and growth. However, they also have been implicated in the response of plants to stress and pathogen attack, and in production of reactive oxygen molecules. This proposal seeks to investigate how mitochondria are involved in these processes, using the latest plant genome information. Potential outcomes include crops better able to cope with environmental stress.Read moreRead less
