Aflatoxins and ochratoxins are among the most important mycotoxins of all producers both types present in
Aspergillus section (formerly the genus Eurotium) includes xerophilic species with uniseriate conidiophores, globose to subglobose vesicles, green conidia and yellow, thin walled eurotium-like ascomata hyaline, lenticular ascospores. In present study, a polyphasic approach using morphological characters, extrolites, physiological characters phylogeny was applied investigate taxonomy of this section. Over 500 strains from various culture collections new isolates obtained indoor environments...
Aspergillus section Restricti together with sister (formerly Eurotium) comprises xerophilic species, that are able to grow on substrates low water activity and in extreme environments. We adressed the monophyly of both sections within subgenus applied a multidisciplinary approach for definition species boundaries sect. Restricti. The was tested set 102 isolates comprising all currently accepted strongly supported by Maximum likelihood (ML) Bayesian inferrence (BI) analysis based β-tubulin...
Although Aspergillus fumigatus is the major agent of invasive aspergillosis, an increasing number infections are caused by its cryptic species, especially A. lentulus and viridinutans species complex (AVSC).Their identification clinically relevant because antifungal drug resistance refractory infections.Species boundaries in AVSC unresolved since most have uniform morphology produce interspecific hybrids vitro.Clinical environmental strains from six continents (n = 110) were characterized...
Since the last revision in 2015, taxonomy of section Flavipedes evolved rapidly along with availability new species delimitation techniques. This study aims to re-evaluate boundaries members using modern methods applied an extended set strains (n = 90) collected from various environments. The analysis used DNA sequences three house-keeping genes ( benA , CaM RPB2 ) and consisted two steps: application several single-locus (GMYC, bGMYC, PTP, bPTP) multi-locus (STACEY) sort isolates into...
Recent DNA-based studies have shown that the built environment is surprisingly rich in fungi. These indoor fungi - whether transient visitors or more persistent residents may hold clues to rising levels of human allergies and other medical building-related health problems observed globally. The taxonomic identity these crucial such pursuits. Molecular identification mycobiome no trivial undertaking, however, given large number unidentified, misidentified, technically compromised fungal...
The genus Codinaea is a phialidic, dematiaceous hyphomycete known for its intriguing morphology and turbulent taxonomic history. This polyphasic study represents new, comprehensive view on the taxonomy, systematics, biogeography of relatives. Phylogenetic analyses three nuclear loci confirmed that polyphyletic. generic concept was emended; it includes four morphotypes contribute to morphological complexity. Ancestral inference showed evolution some traits correlated these previously used...
Aspergillus candidus is a species frequently isolated from stored grain, food, indoor environments, soil and occasionally also clinical material. Recent bioprospecting studies highlighted the potential of using A. its relatives in various industrial sectors as result their significant production enzymes bioactive compounds. A high genetic variability was observed among isolates originating European countries USA, that were mostly caves The sensu lato characterized by DNA sequencing four...
Aspergillus section Nidulantes encompasses almost 80 homothallic and anamorphic species, mostly isolated from soil, plant material, or the indoor environment. Some species are clinically relevant produce mycotoxins. This study reevaluated boundaries within several clades of Nidulantes. Five data sets were assembled, each containing presumptive new their closest relatives, phylogenetic phenotypic analyses performed. We tested hypotheses that newly reexamined strains constitute separate...
Endophytic fungi of crops can promote plant growth through various mechanisms action (i.e., improve nutrient uptake and use efficiency, produce modulate hormones). The genus Brassica includes important horticultural crops, which have been little studied in their interaction with endophytic fungi. Previously, four were isolated from kale roots ( oleracea var. acephala ), different benefits for host, including promotion, cold tolerance, induction resistance to pathogens Xanthomonas campestris...
