Understanding this process is key to the development of drugs against this fatal infection. […]

  • Mite genomes reveal 'mighty surprising' fragrant and colorful secrets
    on November 19, 2018 at 8:59 pm

    Scientists have uncovered some unexpected 'foreign' genes in the tiny itch-inducing chigger mite and its more benign but enormous cousin, the giant velvet mite. Genome sequencing of these mites, both members of the trombidid mite family, reveals them to have functional genes for producing terpenes -- naturally occurring and often fragrant compounds that are commonly found in plants, but extremely rare in the animal world. […]

  • Symbiosis a driver of truffle diversity
    on November 14, 2018 at 7:43 pm

    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. […]

  • Olive oil and fungus protect wood from wood rot
    on November 5, 2018 at 5:25 pm

    A fungus that does not attack wood, but preserves it. It sounds strange, but it is possible. A new study shows that black fungi on oiled wood can behave like a 'biofinish'. This layer colors the wood and protects it from wood rot and degradation by sunlight. An additional advantage: the fungus automatically repairs damage in the protective layer. […]

  • Caterpillar, fungus in cahoots to threaten fruit, nut crops, study finds
    on November 5, 2018 at 5:24 pm

    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 that the two pests work in concert to overcome plant defenses and resist pesticides. […]

The hormone supports the symbiosis between fungi and plant roots, thus encouraging plants' growth -- even under the challenging conditions found in space. […]

  • How beetle larvae thrive on carrion
    on October 15, 2018 at 7:06 pm

    The burying beetle Nicrophorus vespilloides buries the cadavers of small animals to use them as a food source for its offspring. However, the carcass is susceptible to microbial decomposition. Researchers show that the beetles replace harmful microorganisms with their own beneficial gut symbionts, thus turning a carcass into a nursery with a microbial community that even promotes larval growth. […]

  • Unravelling the genetics of fungal fratricide
    on October 15, 2018 at 3:35 pm

    Selfish genes are genes that are passed on to the next generation but confer no advantage on the individual as a whole, and may sometimes be harmful. Researchers have, for the first time, sequenced (or charted) two selfish genes in the fungus Neurospora intermedia that cause fungal spores to kill their siblings. Unexpectedly, the genes were not related to each other, perhaps indicating that selfish genes are more common than previously thought. […]
