Myrtle rust – reducing symptoms with double stranded RNA.

The Foundation has been delighted to support some exciting work at UQ and now the team has published: “Exogenous double-stranded RNA inhibits the infection physiology of rust fungi to reduce symptoms in planta”. Go to the paper online here or go to the Projects page here and check out the various Myrtle Rust projects.


Demographic mapping across gardening communities to inform urban and periurban plant biosecurity engagement strategies

A new report, led by Helen McGregor, Redefining Agriculture. The findings in this project offer insight into both the value and limitations of the community garden networks in Melbourne as a representative model for evaluating plant health education and engagement at a local level. Most notably the importance of a tailored, strategic, integrated approach to […]


Myrtle Rust – The Silent Killer explained in a new short film

Australia’s native plants are experiencing their own pandemic. The myrtle rust fungus is silently killing our seedlings, saplings and established trees. Hundreds of Australian species in the Myrtaceae family are susceptible including bottlebrushes, eucalypts and tea trees with 16 species set to become extinct within a generation. This new short film shares first-hand stories on […]

Fire and Myrtle Rust – a deadly combination!

Geoff Pegg (QDAF) and crew have just finished a two-year study, concluding the impacts of Myrtle Rust on regeneration of native species following fire can be severe, leading to death of many species and potential loss of ecosystem function. Impact from A. psidii infection was identified on all species monitored as part of this study. […]

Indonesia’s Decentralized and Local Responses to COVID-19: Implications for Bilateral Biosecurity Engagement with Australia (PBSF040)

Project Leader Ian Falk, Indonesian Biosecurity Foundation Status Contracting Background This project focuses on plant biosecurity in Indonesia and Australia. Each of its four case studies examines different aspects of effective management of biosecurity so as to generate clear messages for end-users and decision-makers in both countries, aiming to inform a bilateral biosecurity action plan […]

Indigenous artistic and linguistic interpretation of Myrtle Rust and it’s impacts for community awareness (PBSF043) COMPLETE

Project Leader Mark Temple, Western Sydney University Status COMPLETE Background Myrtle rust impacts the flora and ecosystems across the east coast of Australia. Visual impact of the disease includes yellow spores on plant foliage, defoliation, death of plants and invasive with exotic plants. Through engagement with indigenous artists we will represent the impact of myrtle […]

Development of RNAi vaccines for in-field protection of vulnerable Australian ecosystems and industries against myrtle rust (PBSF042)

Project Leader Dr Anne Sawyer, University of Queensland Status Active Background Myrtle Rust Action Plan Objective 4.3 is to explore methods for resistance and control. In an earlier Foundation project (PBSF034) , we developed RNA interference (RNAi)vaccines that reduced myrtle rust infection on Syzygium jambos. We are on track to complete the project this year, […]

The fingerprint of Myrtle Rust – an identification tool …

Using an untargeted metabolomics approach, Michelle Moffitt and team from the University of Western Sydney identified a unique molecular fingerprint in A. psidii infected Melaleuca quinquenervia leaves during the early stages of infection. Further analysis of the metabolome at 24 hours and 48 hours after infection identified a unique subset of 19 metabolites that are unique to the resistant […]

Remote sensing and machine learning applications offer real potential for urban forest biosecurity surveillance

A new report led by Dr angus Carnegie of NSW DPI has shown the potential of using new technologies in combination could save significant time and money for urban forest biosecurity surveillance. This study evaluated high-resolution airborne ArborCam imagery for tree species classification in a complex urban environment. An object instance segmentation of tree crowns […]
