Approximately 88 percent of wheat production is susceptible to yellow rust. Researchers have new results regarding the fungus, which evolves quickly to produce new, virulent strains.
What's a feast for the human eye may be a literal feast for microorganisms that colonize works of art, according to a new study in the open-access journal PLOS ONE by Elisabetta Caselli of the University of Ferrara, Italy, and colleagues. The researchers characterized the microbial community on a 17th century painting and showed that while some microbes destroy such works of art, others might be employed to protect them.
Some fungi are smelly and coated in mucus. Others have gills that glow in the dark. Some are delicious; others, poisonous. Some spur euphoria when ingested. Some produce antibiotics. All of these fungi -- and hundreds of thousands, if not millions, more -- occur in North America. Of those that are known to science, 44,488 appear in a new checklist of North American fungi, published this month in the journal Mycologia.
Russian scientists together with colleagues from UK, Spain, Brazil, Japan and Austria have fully described the mechanism of fungal luminescence. They found that fungi utilize only four key enzymes to produce light and that transfer of these enzymes into other organisms makes them bioluminescent.
A new study by researchers of disease transmission in bats has broad implications for understanding hidden connections that can spread diseases between species and lead to large-scale outbreaks.
Truffles are the fruiting bodies of the ectomycorrhizal (ECM) fungal symbionts residing on host plant roots. In many Ascomycota and Basidiomycota lineages, truffle-forming species have evolved independently in nearly every major group. This suggests that symbiosis drives evolution of truffle diversity and selects for specific traits. As reported in Nature Ecology & Evolution, an international team sought insights into the ECM lifestyle of truffle-forming species, conducting a comparative analysis of eight Pezizomycete fungi.
The BioScience Talks podcast features discussions of topical issues related to the biological sciences.
New research reveals that Aspergillus flavus, a fungus that produces carcinogenic aflatoxins that can contaminate seeds and nuts, has a multilegged partner in crime: the navel orangeworm caterpillar, which targets some of the same nut and fruit orchards afflicted by the fungus. Scientists report in the Journal of Chemical Ecology that the two pests work in concert to overcome plant defenses and resist pesticides.
Infants born at home have more diverse bacteria in their guts and feces, which may affect their developing immunity and metabolism, according to a study in Scientific Reports.
By screening a library of off-patent drugs, scientists have identified a compound with promising broad-spectrum antifungal activity. The compound, alexidine dihydrochloride, warrants further development as a pan-fungal, anti-biofilm drug, according to the research reported in the journal mSphere.
