TLDR
The new species differs by its poor growth on glycerol and galacturonate and its unique extrolite profile consisting of aurasperone B, nigragillin, asperazine and kotanins.Abstract:
A strain from the group of black Aspergilli was analysed in detail to determine the species to which it belongs. A detailed analysis of morphology, RFLP patterns and metabolite profiles was carried out. In addition, a phylogenetic tree was constructed for the black Aspergilli using the ITS and the beta-tubulin sequences of the individual strains. The new species differs by its poor growth on glycerol and galacturonate and its unique extrolite profile consisting of aurasperone B, nigragillin, asperazine and kotanins. RFLP analysis using three genes as probes also resulted in a unique pattern. These data indicate that the strain was closely related but not identical to Aspergillus foetidus, Aspergillus niger and Aspergillus tubingensis. It was therefore designated as a novel species and named Aspergillus vadensis.read more

TL;DR: The genome of M. graminicola was sequenced completely and found that it contained very few genes for enzymes that break down plant cell walls, which was more similar to endophytes than to pathogens, which may have evolved from endophytic ancestors.

TL;DR: The present taxonomy of the black aspergilli reveals that there are 19 accepted taxa, however the identification of species of Aspergillus section Nigri is often problematic in spite of the existence of numerous methods proposed.

TL;DR: Compounds such as malformins, naptho-γ-pyrones, and bicoumarins (kotanins) call for monitoring in food, feed, and biotechnology products as well as for a better toxicological evaluation, since they are often produced in large amounts by the black aspergilli.

TL;DR: A four locus DNA sequence study covering all major lineages in Aspergillus using genealogical concordance theory resulted in a species recognition system that agrees in part with phenotypic studies and reveals the presence of many undescribed species not resolved by phenotype.

TL;DR: Nine sets of oligonucleotide primers constructed on the basis of the results of DNA hybridization of cloned genes from Neurospora crassa and Aspergillus nidulans may provide useful tools for phylogenetic studies and genome analyses in filamentous ascomycetes and deuteromycete affiliations, as well as for the rapid differentiation of fungal species by PCR.
