The Myrtle rust pathogen, Puccinia psidii, discovered in Africa
Puccinia psidii, the cause of a disease today commonly referred to as Myrtle rust, is considered a high priority quarantine threat globally. It has a wide host range in the Myrtaceae and it is feared that it may result in significant damage to native ecosystems where these plants occur. The fungus is also of considerable concern to plantation forestry industries that propagate Australian Eucaly...
متن کاملA preliminary assessment of high risk areas for Puccinia psidii (Eucalyptus rust) in the Neotropics and Australia
Puccinia psidii Winter, which causes both guava rust and eucalypt rust, is an important pathogen on eucalypts and other members of the Myrtaceae family in the Neotropics. If introduced into Australia it could represent a major potential threat to eucalypt plantations as well as native vegetation. Observations of the distribution of eucalypt rust epidemics in the Neotropics were analysed to deve...

متن کاملImpact of Austropuccinia psidii (myrtle rust) on Myrtaceae-rich wet sclerophyll forests in south east Queensland
In April 2010, Austropuccinia psidii (formerly Puccinia psidii) was detected for the first time in Australia on the central coast of New South Wales. The fungus spread rapidly along the east coast and can now be found infecting vegetation in a range of native forest ecosystems with disease impacts ranging from minor leaf spots to severe shoot and stem blight and tree dieback. Localised extincti...
متن کاملLabel-Free Quantitative Proteomic Analysis of Puccinia psidii Uredospores Reveals Differences of Fungal Populations Infecting Eucalyptus and Guava
Puccinia psidii sensu lato (s.l.) is the causal agent of eucalyptus and guava rust, but it also attacks a wide range of plant species from the myrtle family, resulting in a significant genetic and physiological variability among populations accessed from different hosts. The uredospores are crucial to P. psidii dissemination in the field. Although they are important for the fungal pathogenesis,...
