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.

Discovering the activity of novel CLE peptide hormones that regulate legume nodulation. This project aims to functionally characterise novel peptide hormones that regulate the number of nitrogen-fixing root nodules that legumes form. Findings will enhance the current nodulation model and could help to alleviate our reliance on expensive, often polluting, nitrogen-fertilisers by helping to optimise the nodulation process in agriculture.
Discovery of the systemic regulator of legume nodulation. This project aims to discover the novel, shoot-derived factor that legumes produce to regulate the number of nitrogen-fixing root nodules they form. Outcomes will enhance the current nodulation model and could help optimise the process in agriculture, which would help alleviate current reliance on nitrogen-fertilisers that are expensive and pollute.
The Role of Sugar Demand in Apical Dominance: Branching in a New Direction. For centuries, people around the world have made use of the knowledge that pruning the growing tips of shoots causes buds on the stem below to grow out into branches. Yields in crop, horticulture and forestry industries depend on shoot architecture. Since the discovery of auxin in the 1930s, shoot branching has been thought to be regulated by plant hormones. However, in this project we propose a new theory whereby shoot ....The Role of Sugar Demand in Apical Dominance: Branching in a New Direction. For centuries, people around the world have made use of the knowledge that pruning the growing tips of shoots causes buds on the stem below to grow out into branches. Yields in crop, horticulture and forestry industries depend on shoot architecture. Since the discovery of auxin in the 1930s, shoot branching has been thought to be regulated by plant hormones. However, in this project we propose a new theory whereby shoot tip demand for sugar is predominant in apical dominance; enhanced sucrose, a mobile sugar, is necessary and sufficient for the initial growth of buds. This project aims to expand this theory, revealing underlying components involved in sucrose action and describe how the network of sugar demand and hormones acts to control shoot architecture.Read moreRead less
