Novel species of microfungi described in the present study include the following from Australia: Bagadiella victoriae and Bagadiella koalae on Eucalyptus spp., Catenulostroma eucalyptorum on Eucalyptus laevopinea, Cercospora eremochloae on Eremochloa bimaculata, Devriesia queenslandica on Scaevola taccada, Diaporthe musigena on Musa sp., Diaporthe(More)
Many fungi are pathogenic on plants and cause significant damage in agriculture and forestry. They are also part of the natural ecosystem and may play a role in regulating plant numbers/density. Morphological identification and analysis of plant pathogenic fungi, while important, is often hampered by the scarcity of discriminatory taxonomic characters and(More)
The extent and importance of endogenous viral elements have been extensively described in animals but are much less well understood in plants. Here we describe a new genus of Caulimoviridae called 'Florendovirus', members of which have colonized the genomes of a large diversity of flowering plants, sometimes at very high copy numbers (>0.5% total genome(More)
Two species of rust fungi, Uredinopsis pteridis on Pteridium esculentum and Desmella aneimiae on Nephrolepis hirsutula, are reported from Australia. These are the first records of rust fungi on species of fern in Australia and the first reports of the genera Uredinopsis and Desmella in Australia.
Systematic relationships between the rusts on Goodeniaceae and Stylidiaceae were examined using phylogenetic analyses with two loci (internal transcribed spacer, large subunit region) from ribosomal DNA. Fresh specimens and herbarium material of four rust species (Puccinia dampierae, P. gilgiana, P. saccardoi and Uromyces scaevolae) from the Goodeniaceae(More)
Interactive identification keys for Australian smut fungi (Ustilaginomycotina and Pucciniomycotina, Microbotryales) and rust fungi (Pucciniomycotina, Pucciniales) are available online at http://collections.daff.qld.gov.au. The keys were built using Lucid software, and facilitate the identification of all known Australian smut fungi (317 species in 37(More)
Proteins in the Glycoside Hydrolase family 32 (GH32) are carbohydrate-active enzymes known as invertases that hydrolyse the glycosidic bonds of complex saccharides. Fungi rely on these enzymes to gain access to and utilize plant-derived sucrose. In fungi, GH32 invertase genes are found in higher copy numbers in the genomes of pathogens when compared to(More)
☯ These authors contributed equally to this work. Microorganisms have inadvertently been spread via the global movement and trade of their sub-strates, such as animals, plants, and soil. This intercontinental exchange in the current era of globalisation has given rise to significant increases in the distribution of known pests and pathogens. Importantly, it(More)
The gall rusts on Acacia spp. and Paraserianthes falcataria are caused by species of Uromycladium. Morphology and a phylogenetic analysis of four loci from ribosomal (SSU, ITS, LSU) and mitochondrial (CO3) DNA, showed that the rust on P. falcataria differed from U. tepperianum. Uromycladium falcatarium sp. nov. is described to accommodate this taxon, which(More)
