The use of compounds produced by hosts or symbionts for defence against antagonists has been identified in many organisms, including in fungus-farming termites (Macrotermitinae). The obligate mutualistic fungus Termitomyces plays a central role in the symbiosis through plant biomass decomposition and as the main food source for these termites. Seve...

Fungus-farming termite colonies maintain monoculture fungus combs in underground chambers without apparent problems with diseases. Multiple lines of defense contribute to the suppression or removal of antagonists of the symbiosis, but the role of the termite-manipulated environment within mounds has yet to be tested. Specifically, termite mounds ha...

Fungus‐farming termites are dominant decomposers and important ecosystem engineers in their natural sub‐Sahara African and Southeast Asian ecosystems. This is accomplished through integrated behavioral management of complex communities of fungal and bacterial symbionts by the termite host that facilitate plant biomass decomposition and production o...

The neglected area of Khyber Pakhtunkhwa (Pakistan: Oriental region), consisting of Buner, Haripur, and Swabi districts, were surveyed for termites during the summer of 2016–2019 for identification and assessment of the distribution of colonies. Collections were made either directly from visible galleries or using traps with ethanol. Soldiers were...

There are few protocols available for DNA extraction from fungi. Here we present four complementary protocols for extraction of genomic DNA from fungi. We quantify the efficacy of extractions and compare eight species from five filamentous fungal genera, including both basidiomycetes and ascomycetes. These protocols should be useful for extraction...

Macrotermitinae termites have domesticated fungi of the genus Termitomyces as food for their colony, analogously to human farmers growing crops. Termites propagate the fungus by continuously blending foraged and predigested plant material with fungal mycelium and spores (fungus comb) within designated subterranean chambers. To test the hypothesis t...

Fungus-farming termites host gut microbial communities that contribute to the pre-digestion of plant biomass for manuring the fungal mutualist, and potentially to the production of defensive compounds that suppress antagonists. Termite colonies are characterized by complex division of labor and differences in diet between termite size (minor and ma...

Covering: September 1972 to December 2020Explorations of complex symbioses have often elucidated a plethora of previously undescribed chemical compounds that may serve ecological functions in signalling, communication or defence. A case in point is the subfamily of termites that cultivate a fungus as their primary food source and maintain complex b...

DNA methylation patterns may be used for identification of body fluids and for age estimation of human individuals. We evaluated some of the challenges and pitfalls of studying methylated CpG sites. We compared the methylated CpG analysis of two different methods 1) massively parallel sequencing (MPS) using the Illumina MiSeq and 2) the iPLEX assay...

Control of the potato late blight pathogen Phytophthora infestans relies heavily on chemicals. The fungicide Metalaxyl-M (Mefenoxam) has played an important role in controlling the disease, but insensitivity to the fungicide in certain isolates is now of major concern. A genetic basis for resistance to Metalaxyl suggests the possibility for linking...
