A review of the Ustilago-Sporisorium-Macalpinomyces complex
Provedor de dados: 16
Autores: McTaggart, A.R.; Shivas, R.G.; Geering, A.D.W.; Vánky, K.; Scharaschkin, T.
The fungal genera Ustilago, Sporisorium and Macalpinomyces represent an unresolved complex. Taxa within the complex often possess characters that occur in more than one genus, creating uncertainty for species placement. Previous studies have indicated that the genera cannot be separated based on morphology alone. Here we chronologically review the history of the Ustilago-Sporisorium-Macalpinomyces complex, argue for its resolution and suggest methods to accomplish a stable taxonomy. A combined molecular and morphological approach is required to identify synapomorphic characters that underpin a new classification. Ustilago, Sporisorium and Macalpinomyces require explicit re-description and new genera, based on monophyletic groups, are needed to accommodate...

A co-evolutionary relationship exists between Endoraecium (Pucciniales) and its Acacia hosts in Australia
Provedor de dados: 16
Autores: McTaggart, A.R.; Doungsa-ard, C.; Geering, A.D.W.; Aime, M.C.; Shivas, R.G.
Endoraecium is a genus of rust fungi that infects several species of Acacia in Australia, South-East Asia and Hawaii. This study investigated the systematics of Endoraecium from 55 specimens in Australia based on a combined morphological and molecular approach. Phylogenetic analyses were conducted on partitioned datasets of loci from ribosomal and mitochondrial DNA. The recovered molecular phylogeny supported a recently published taxonomy based on morphology and host range that divided Endoraecium digitatum into ﬁve species. Spore morphology is synapomorphic and there is evidence Endoraecium co-evolved with its Acacia hosts. The broad host ranges of E. digitatum, E. parvum, E. phyllodiorum and E. violae-faustiae are revised in light of this study, and nine...

Diversity of gall-forming rusts (Uromycladium, Pucciniales) on Acacia in Australia
Provedor de dados: 16
Autores: Doungsa-ard, C.; McTaggart, A.R.; Geering, A.D.W.; Shivas, R.G.
Uromycladium tepperianum has been reported on over 100 species of Acacia, as well as on the closely related plant genera, Falcataria, Racosperma and Paraserianthes. Previous studies have indicated that U. tepperianum may represent a complex of host-specific, cryptic species. The phylogenetic relationships between 79 specimens of Uromycladium were determined based on a concatenated dataset of the Small Subunit, the Internal Transcribed Spacer and the Large Subunit regions of nuclear ribosomal DNA, and the mitochondrial cytochrome c oxidase subunit 3. This study showed that the host range of U. tepperianum s.str. was restricted to species of Acacia in the ‘A. bivenosa group’ sensu Chapman &amp; Maslin (1992). An epitype of U. tepperianum on A. ligulata is...

Taxonomic revision of Ustilago, Sporisorium and Macalpinomyces
Provedor de dados: 16
Autores: McTaggart, A.R.; Shivas, R.G.; Geering, A.D.W.; Vánky, K.; Scharaschkin, T.
Morphological characters within the Ustilago-Sporisorium-Macalpinomyces complex are defined explicitly. The genera Sporisorium and Anthracocystis are emended to reflect morphological synapomorphies. Three new genera, Langdonia, Stollia and Triodiomyces are described based on soral synapomorphies and host classification. The new classification of the Ustilago-Sporisorium-Macalpinomyces complex incorporates 142 new taxonomic combinations.

Soral synapomorphies are significant for the systematics of the Ustilago-Sporisorium- Macalpinomyces complex (Ustilaginaceae)
Provedor de dados: 16
Autores: McTaggart, A.R.; Shivas, R.G.; Geering, A.D.W.; Callaghan, B.; Vánky, K.; Scharaschkin, T.
The genera Ustilago, Sporisorium and Macalpinomyces are a polyphyletic complex of plant pathogenic fungi. The four main morphological characters used to define these genera have been considered homoplasious and not useful for resolving the complex. This study re-evaluates character homology and discusses the use of these characters for defining monophyletic groups recovered from a reconstructed phylogeny using four nuclear loci. Generic delimitation of smut fungi based on their hosts is also discussed as a means for identifying genera within this group. Morphological characters and host specificity can be used to circumscribe genera within the Ustilago-Sporisorium-Macalpinomyces complex.
