Fungal mycelia are exposed to heterogenic substrates. The substrate in the central part of the colony has been (partly) degraded, whereas it is still unexplored at the periphery of the mycelium. We here assessed whether substrate heterogeneity is a main determinant of spatial gene expression in colonies of Aspergillus niger. This question was addressed by analyzing whole-genome gene expression ...

Cordyceps militaris has recently been used as a functional food in China and is commonly used as a Traditional Chinese Medicine. The formation of C. militaris fruiting bodies is unstable and is a limiting factor for industrial production. Fruiting body formation and quantities of adenine, adenosine and cordycepin differed significantly between the phenotypes. Orange chrome colonies produced fru...

The worldwide decline in honeybee colonies during the past 50 years has often been linked to the spread of the parasitic mite Varroa destructor and its interaction with certain honeybee viruses. Recently in the United States, dramatic honeybee losses (colony collapse disorder) have been reported; however, there remains no clear explanation for these colony losses, with parasitic mites, viruses,...

Four halotolerant fungal isolates originating from the saltwater Lake Urmia in Iran were selected during a screening program for salt resistance and α-amylase activity. The isolates were identified based on sequencing the ITS region and a part of the β-tubulin gene, as Penicillium chrysogenum (isolate U1; CBS 132820), Fusarium incarnatum (isolate U2; CBS 132821), and Penicillium polonicum (isol...

Polyamines play a regulatory role in eukaryotic cell growth and morphogenesis. Despite many molecular advances, the underlying mechanism of action remains unclear. Here, we investigate a mechanism by which spermine affects the morphogenesis of a dimorphic fungal model of emerging relevance in plant interactions, Yarrowia lipolytica, through the recruitment of a phytohormone-like pathway involvi...

The objectives of this 14 days experiment were to investigate the effect of spaceflight on the growth of Ulocladium chartarum, to study the viability of the aerial and submerged mycelium and to put in evidence changes at the cellular level. U. chartarum was chosen for the spaceflight experiment because it is well known to be involved in biodeterioration of organic and inorganic substrates cover...

Chemical fungicides viz. propiconazole, thiram, bayleton, copper-oxy-chloride, benomyl and mancozeb in three different concentrations were screened for their fungicidal efficacy against P. pinnata seed mycoflora viz., Penicillium sp., A. oryzae, A. ustus, A. sydowii, A. fumigatus, A. flavus, A. niger, Rhizopus sp., Fusarium sp., C. gloeosporioides and Absidia sp. in in-vitro conditions by poiso...
