  • Scientists map sex chromosome evolution in pathogenic fungi
    on August 11, 2017 at 8:25 pm

    Researchers recently mapped the evolutionary turning point that transformed the pathogenic Cryptococcus fungus from an organism with thousands of sexes to only two. They found that during evolution, a reshuffling of DNA known as translocation brought together separate chunks of sex-determining genes onto a single chromosome, essentially mimicking the human X or Y chromosome. Surprisingly, these translocations occurred at the chromosome's centromeres, regions so dense that they were once thought to suppress recombination. […]

  • Fungi are key players of the deep biosphere
    on July 4, 2017 at 1:39 pm

    In addition to the life on the surface of the Earth and in its oceans, ecosystems have evolved deep under us in a realm coined the “deep biosphere” which stretches several kilometers down into the bedrock. Down there, the conditions are harsh and life is forced to adjust to a lifestyle that we at the surface would call extreme. One major difference to surface conditions is the lack of oxygen; a compound we take for granted and consider to be a prerequisite for survival but which subsurface life has to cope without. […]

  • Soybean rust study will allow breeders to tailor resistant varieties to local pathogens
    on June 28, 2017 at 9:21 pm

    Midwestern growers don't worry much about soybean rust, but the fungal disease has been popping up at the end of the growing season nearly every year since 2006. But because the fungus can't survive winter without a host plant, it's not much of a threat to Midwest crops under current conditions. But it's a major problem for soybean growers in Africa and South America. Researchers have evaluated which strains are most virulent. […]
