Tracking Plant, Fungal, and Bacterial DNA in Honey Specimens*

Journal of Forensic Sciences, 2011
Abstract:  Consuming honey can result in adverse effects owing to poisoning by bacterial (botulism) or plant toxins. We have devised a method to extract polymerase chain reaction (PCR) amplifiable DNA of up to c. 400 bp in length based on dialysis of a 15‐mL honey sample for 18 h against deionized water followed by sequential extraction using phenol ...

Furry pet allergens, fungal DNA and microbial volatile organic compounds (MVOCs) in the commercial aircraft cabin environment.

Environmental Science: Processes & Impacts, 2013
There has been concern about the cabin environment in commercial aircraft. We measured cat, dog and horse allergens and fungal DNA in cabin dust and microbial volatile organic compounds (MVOCs) in cabin air.

Endophytic fungal DNA, the source of contamination in spruce needle DNA

Molecular Ecology, 1997
DNA isolated and amplified from higher plants may originate from symbiotic microbes occupying plant tissues. A recent report on the phylogeny of Picea contained sequence data that upon later analysis proved to originate from filamentous ascomycetes. Isolates of endophytic fungi from Picea foliage collected from the same location as the original samples

Fungal Nails? DNA Facts Challenge Dystrophic Etiology

Journal of the American Podiatric Medical Association, 2021
Abstract Historically recalcitrant to treatment, infection of the nail unit is a pervasive clinical condition affecting about 10%-20% of the U.S. population; patients present with both cosmetic symptomatology and pain, with subsequent dystrophic morphology. To date, the presumptive infectious etiologies include classically-reported fungal dermatophytes,

Nuclear DNA content of 11 fungal species in Glomales

Genome, 1998
The nuclear DNA content of 11 species of Glomales was evaluated by flow cytometry after DAPI staining relative to Gigaspora margarita, which was used as internal standard. The nuclear DNA content of this species was calibrated by propidium iodide staining relative to chicken red blood cells. A correction was applied when the difference in AT content of

DNA barcodes for marine fungal identification and discovery

Fungal Ecology, 2013
Abstract We employed DNA barcodes for identification of fungal species in marine sediments. Sediments were collected seasonally along the Southeast coast of India from which a culturable fungal library was constructed. All cultured species were morphologically documented using microscopical analysis. A maximum population density of 19.3 × 10 3  CFU/g

A simple method for a mini-preparation of fungal DNA

Journal of General Plant Pathology, 2006
A simple method was established to prepare DNA from fungal mycelia cultured on an agar plate. The fungi tested successfully with this method contained Zygomycetes, Ascomycetes, Basidiomycetes, and Oomycetes. This method did not require any time-consuming steps to crush or digest mycelia or fractionation in a phenol–chloroform mixture.

Plant biomass and Fungal DNA abundance

, 2015
Plant biomass and AM fungal abundance in roots data were collected from a 12 week glasshouse experiment. Pot=Pot number, Plant=Plant community: (Tri = Trifolium monoculture, Lol = Lolium monoculture, Pla = Plantago monoculture, Mix = mixture of all three

Multipartite structure of mitochondrial DNA in a fungal longlife mutant

Plasmid, 1989
Rearrangements in the mitochondrial genome of the longlife mutant ex1 of the ascomycete Podospora anserina have led to a heterogeneous population of subgenomic molecules. The restriction maps of individual subcircles were established using overlapping recombinant lambda phages isolated from an ex 1 mtDNA/EMBL3 library.

Preparation of mitochondrial DNA from fungal protoplasts

Journal of Microbiological Methods, 1997
A rapid and simple method based on protoplast formation is presented to prepare mitochondrial DNA (mtDNA) from filamentous fungi. This protocol can be applied to prepare mtDNA from numerous strains in relatively short time.
