Impact 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 کاملThe 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 کاملPerspective : Transposable Elements , Parasitic Dna , and Genome
The nature of the role played by mobile elements in host genome evolution is reassessed considering numerous recent developments in many areas of biology. It is argued that easy popular appellations such as ‘‘selfish DNA’’ and ‘‘junk DNA’’ may be either inaccurate or misleading and that a more enlightened view of the transposable element-host relationship encompasses a continuum from extreme pa...
متن کاملTransposable elements in human cancers by genome-wide EST alignment.
Transposable elements may affect coding sequences, splicing patterns, and transcriptional regulation of human genes. Particles of the transposable elements have been detected in several tissues and tumors. Here, we report genome-wide analysis of gene expression regulated by transposable elements in human cancers. We adopted an analysis pipeline for screening methods to detect cancer-specific ex...
متن کاملTransposable elements and host genome evolution.
Several recent reports have challenged the idea that transposable elements (TEs) are mainly 'selfish' or 'junk' DNA with little importance for host evolution. It has been proposed that TEs have the potential to provide host genomes with the ability to enhance their own evolution. They might also be a major source of genetic diversity, allowing response to environmental changes. Because the rela...
