Button Mushroom Marks Niche in Forest Carbon Storage

Many people know the button mushroom (Agaricusbisporus) as a tasty ingredient in their food. In the forest, though, this mushroom helps break down leaf litter in environments rich with humus, a mixture of soil and compost that contributes to the health of the microbial communities in, on and around the plant as well as the… [Read More]

Comparing White Rots to Shed Light on Wood-Colonizing Habit

White-rot basidiomycetes can degrade all components of lignocellulosicbiomass, including lignin, cellulose and hemicellulose. Thus, harnessing the metabolic potential of these organisms is key to developing cost-effective technologies for the production of renewable energy and value-added co-products from residual plant biomass. A comparative analysis of the white rot fungus, Phanerochaetecarnosa, isolated from softwoods, andPhanerochaetechrysosporium, isolated from… [Read More]

Targeted metagenomics approach pins down role of “wild” alga

Marine microbes play key roles in cycling carbon between the atmosphere and the ocean depths, but little is known about their populations throughout the waters. As global temperatures change, so do these populations, which in turn impacts their contributions to the carbon cycle. Researchers want to learn more about these effects, but one of the… [Read More]

Algal Lipid Pathways Linked to Those in Plants and Fungi

Red algae play an important role in carbon and nitrogen cycles in the ocean, and are potential biomass for biofuel production. However, few red algae have been studied at the genomic level to date. An international collaboration of researchers has found that some species of the extremophilic red algae Porphyra have a pathway similar to… [Read More]

Methylobacteria Shed Light on the C and N Cycles

Methylobacteriaare vital for processing single-carbon compounds like methanol, methylamine, and the greenhouse gas methane. They play a central role in the carbon and nitrogen cycle. While many researchers are studying the bacteria, their full functionality is still unknown– but it’s becoming more complete, thanks to a recent publication of six genomes of different strains of… [Read More]

Drifting Poplar Populations Inform Breeding Strategies

Since the publication of the genome sequence of the first tree, the black cottonwood or poplar Populustrichocarpain 2006 by the DOE Joint Genome Institute, a growing community of researchers have been engaged in advancing the development of poplar as a candidatefeedstockfornext-generationbiofuelsowing to the tree’s compact genome, rapid growth and life cycle. One area of study… [Read More]

Rethinking Rhodanobacter

Denitrification, or breaking down nitrates in soil, is important. It removes the chemicals from potentially contaminating groundwater, but it can also release nitrous oxide, a greenhouse gas, into the atmosphere. Scientists discovered that many species of the low-pH dwelling bacteria in the Rhodanobactergenus are capable of denitrification. This is on the heels of the discovery… [Read More]

Prototypical genomic study of Plant-Microbe Interaction

Instead of using dangerous and toxic pesticides or expensive fertilizers, farmers may one day use microbes to fully manage diseases in soil. Already the microbial community in and surrounding plant roots fights pests and manages carbon and other soil nutrients, ultimately contributing to plant health and growth. What’s more, they aid plants in sequestering pollutants…. [Read More]

Understanding a Cereal Disease with DNA Sequencing

An international coalition of researchers, including those from the DOE Joint Genome Institute have now isolated the Barley stripe mosaic virus resistance gene from  Brachypodium distachyon. They found the single dominant gene responsible by analyzing the offspring of intercrossed disease-resistant and disease-susceptible Brachypodium. Their results were published in June in PLoSOne. Brachypodium distachyonis a good… [Read More]
