  • The two faces of rot fungi
    on June 22, 2017 at 2:38 pm

    Yogurt, beer, bread and specialties such as tasty blue cheeses or good wine -- special microorganisms and refining processes first produce the pleasant flavors and enticing aromas of many foodstuffs. Researchers have now investigated the formation of rot in grapes and have shown that when this is caused by certain kinds of mold fungi, the resultant wine can have not only moldy but also floral aromas. […]

    on June 13, 2017 at 2:19 pm

    A mosquito-killing fungus genetically engineered to produce spider and scorpion toxins could serve as a highly effective biological control mechanism to fight malaria-carrying mosquitoes, scientists report. The fungus is specific to mosquitoes and does not pose a risk to humans. Further, the study results suggest that the fungus is also safe for honey bees and other insects. […]

  • Technology unlocks mold genomes for new drugs
    on June 12, 2017 at 3:54 pm

    Fungi are rich sources of natural molecules for drug discovery, but numerous challenges have pushed pharmaceutical companies away from tapping into this bounty. Now scientists have developed technology that uses genomics and data analytics to efficiently screen for molecules produced by molds to find new drug leads -- maybe even the next penicillin. From three diverse fungal species, the research team discovered 17 new natural products. […]

  • Growth mechanism of fungi decoded
    on June 8, 2017 at 4:36 pm

    Fungi grow with tubular cells extending by kilometers. Growth takes place exclusively at the tip. Researchers have now found out how this works: construction materials are transported on rails through the fungal cells and used at their outermost tip. Calcium concentration at the end of the cell defines when this happens. […]

  • World's oldest fossil mushroom found
    on June 7, 2017 at 6:13 pm

    Roughly 115 million years ago, when the ancient supercontinent Gondwana was breaking apart, a mushroom fell into a river and began an improbable journey. Its ultimate fate as a mineralized fossil preserved in limestone in northeast Brazil makes it a scientific wonder, scientists report. […]

  • Fungi awake bacteria from their slumber
    on June 7, 2017 at 12:53 pm

    When a soil dries out, this has a negative impact on the activity of soil bacteria. Using an innovative combination of state-of-the-art analysis and imaging techniques, researchers have now discovered that fungi increase the activity of bacteria in dry and nutrient-poor habitats by supplying them with water and nutrients. The ability of fungi to regulate drought stress in soil and thus sustain ecosystem functions is an important insight in the context of climate change. […]

  • Intestinal fungi worsen alcoholic liver disease
    on May 23, 2017 at 12:32 pm

    Liver cirrhosis is the 12th leading cause of mortality worldwide and approximately half of those deaths are due to alcohol abuse. Yet apart from alcohol abstinence, there are no specific treatments to reduce the severity of alcohol-associated liver disease. Researchers have now linked intestinal fungi to increased risk of death for patients with alcohol-related liver disease. […]

    on May 18, 2017 at 7:38 pm

    Using neutron crystallography, research team has mapped the three-dimensional structure of a protein that breaks down polysaccharides, such as the fibrous cellulose of grasses and woody plants, a finding that could help bring down the cost of creating biofuels. […]

  • Deadly flower power? Imported tulip bulbs spread anti-fungal resistance
    on May 18, 2017 at 2:40 pm

    Tulip and narcissus bulbs imported into Ireland from the Netherlands may be acting as vehicles for the international spread of a drug-resistant fungus -- with potentially fatal consequences. Experts advise people not to plant bulbs near hospitals or to gift them to at-risk patients. […]

  • Time flies: Insect fossils in amber shed light on India's geological history
    on May 17, 2017 at 1:06 pm

    Researchers have identified three new species of insects encased in Cambay amber dating from over 54 million years ago. Researchers describe the new species of fungus gnats, which provide further clues to understanding India's past diversity and geological history. […]

  • Gladiator games: In the natural world, biodiversity can offer protection to weaker species
    on May 15, 2017 at 3:15 pm

    In a study of competition among fungal species, researchers have found that biodiversity tends to beget biodiversity, a finding that could help in efforts to protect some of the world's most threatened ecosystems, including coral reefs. […]

  • Microscopic soil creatures could orchestrate massive tree 'migrations'
    on May 8, 2017 at 10:49 pm

    Warming temperatures are prompting some tree species in the Rocky Mountains to 'migrate' to higher elevations in order to survive. Researchers have discovered that tiny below-ground organisms play a role in this phenomenon -- and could be used to encourage tree migration in order to preserve heat-sensitive species. Their work shows how these invisible biotic communities create 'soil highways' for young trees, meaning they could determine how quickly species march uphill, if at all. […]

  • New major gene expression regulator in fungi
    on May 8, 2017 at 3:24 pm

    Changing a single letter, or base, in an organism's genetic code impact its traits. Subtler changes can and do happen: in eukaryotes, one such modification involves adding a methyl group to base 6 of adenine (6mA). Researchers report the prevalence of 6mA modifications in the earliest branches of the fungal kingdom. This little-explored realm provides a repertoire of important and valuable gene products for DOE missions in bioenergy and environment. […]

  • Oldest orchid fossil on record identified
    on May 4, 2017 at 1:32 pm

  • Symbiotic bacteria: From hitchhiker to beetle bodyguard
    on April 28, 2017 at 12:43 pm

    Bacterial symbionts transition between plant pathogenicity and insect defensive mutualism, a new report demonstrates. The bacterium Burkholderia gladioli lives in specific organs of a plant-feeding beetle and defends the insect's eggs from detrimental fungi by producing antibiotics. However, when transferred to a plant, the bacterium can spread throughout the tissues and negatively affect the plant. […]

  • Mushrooms get defensive
    on April 27, 2017 at 3:22 pm

    Some mushrooms produce long-chain unsaturated carboxylic acids as their chemical defense against insect larvae. The biosynthesis of these polyenes relies on only one enzyme, as scientists have now discovered. They report the unprecedented multiple double-bond-shifting activity by the enzyme, which is representative of a yet uncharacterized phylogenetic clade of polyketide synthases. […]
