A Rotten Coaltastrophe

Much of the world’s coal was generated 300-360 million years ago, during an era known as the Carboniferous period. But it may have come to an end from an unlikely source: fungus. An international team of scientists, including researchers at Clark University and the U.S. Department of Energy Joint Genome Institute (DOE JGI), has proposed… [Read More]

Linking white rot fungi and the Carboniferous period in Scientific American

Now a new genomic analysis suggests why Earth significantly slowed its coal-making processes roughly 300 million years ago—mushrooms evolved the ability to break down lignin. “These white rot fungi are major decomposers of wood and the only organism that achieves substantial degradation of lignin,” explains mycologist David Hibbett of Clark University in Massachusetts, who led the research… [Read More]

Dekkera yeast project in Science Daily

The yeast Dekkera bruxellensis plays an important role in the production of wine, as it can have either a positive or a negative impact on the taste. Researchers at Lund University in Sweden, among others, have analyzed the yeast’s genome sequenced by the US Department of Energy Joint Genome Institute, giving wine producers the possibility to take… [Read More]

Lessons from the adaptive strategies of a fungal pathogen

  by  ressaure Coniferous forests in Europe and North America have suffered several hundred million dollars in damages annually from the fungal pathogen Heterobasidion annosum. Aside from the economic losses, scientists are concerned by the white rot fungus that not only breaks down the wood for nutrients, but also releases the carbon dioxide trapped in the… [Read More]

Effects of symbiosis on a fungal transcriptome

The soils of the boreal forests in the northern latitudes are estimated to store more than three times the amount of carbon contained in the atmosphere or in plant life on land. Recent studies suggest the relationship between fungi on the forest floor, plants and the microbial communities at the plant roots (or rhizosphere) plays… [Read More]

White rot fungal genomics analysis on EcoSeed

Scientists at the Energy Department’s Joint Genome Institute are comparing the genetic structure of two strains of white rot fungi in order to develop better enzymes for biofuel production.White rot fungi digest moist wood, causing it to rot and decay. These fungi possess natural enzymes that break down the cellulose, hemicelluloses and lignin of plant… [Read More]

Searching for the basis of ligninolytic selectivity

Many fungal genome projects being carried out at the DOE JGI focus on understanding how enzymes can break down cellulose and lignin, the two most abundant biopolymers on Earth, in order to harness these capabilities for industrial applications such as biofuels production. Scanning electron micrograph of Ceriporiopsissubvermispora mycelium on wood.  (Robert Blanchette, University of Minnesota)… [Read More]

DOE JGI Genomics of Energy and Environment Meeting coverage by GenomeWeb

Purdue University’s Jody Banks kicked off the scientific sessions at the US Department of Energy Joint Genome Institute’s 7th annual User Meeting in Walnut Creek, Calif., this week with her talk on the Selaginella genome and how sequencing diverse species could help researchers understand plant evolution.

Elucidating bacteria’s roles in ant fungal gardens

Leafcutter ants cultivate fungal gardens that serve as their primary food source. Working toward the goal of harnessing novel enzymes for breaking down plant biomass to produce cellulosic biofuels, Great Lakes Bioenergy Research Center (GLBRC) researchers have been studying the process by which the fungi break down the plant leaves harvested by the ants and… [Read More]

The role of hydrophobins in plant-fungal mutualism

To get an idea of the importance of mutualistic relationships between plants and fungi, consider that a third of the carbon sequestered in the soil of boreal forests are composed of the wood residues after the fungi break down the cellulose. Maintaining the interface between the fungi and their hosts is the job of small… [Read More]
