A.niger genome project on The Bioenergy Site

Published online ahead of print May 4, 2011 in Genome Research, a team led by Scott Baker of the Pacific Northwest National Laboratory compared the genome sequences of two Aspergillus niger strains to, among other things, better harness its industrial potential in biofuels applications. As more than a million tons of citric acid are produced annually, the production… [Read More]

Fungal lessons for large-scale “green” chemical production

The chemical compound citric acid has been produced on a large-scale basis for decades with the help of the filamentous fungus Aspergillus niger. The fungus also has enzymes that can be used to help break down plant cell walls for biofuel production, and it plays a key role in the carbon cycle. Aspergillus niger (Sue… [Read More]

Selaginella genome project in Biofuels Journal

Published online May 5 in Science Express, a team of researchers from over 60 institutions, that included DOE JGI’s Dan Rokhsar and Igor Grigoriev, the senior authors of this work, reported the genome sequence of Selaginella moellendorffii and used a comparative genomics approach to identify the core genes that are likely to be present in a common ancestor… [Read More]

Selaginella genome project in Western Farm Press

“There are only three families and about 1,000 species of lycophytes remaining. Selaginella has been on Earth about 200 million years,” said Banks, whose findings were published Thursday (May 5) in the journal Science. “This plant is a survivor. It has a really long history and it hasn’t really changed much over time. When you… [Read More]

Selaginella genome project in CORDIS Wire

This genome, sequenced by the Joint Genome Institute of the U.S. Department of Energy, is expected to give scientists a better understanding of how plants of all kinds evolved over the past 500 million years. Banks, a professor of botany and plant pathology, led a team of about 100 scientists from 11 countries to sequence… [Read More]

Poplar leaf rust genome project on SeedQuest

Sequenced at the DOE JGI using the Sanger platform under the 2006 Community Sequencing Program, the 101-million base pair genome of Melampsora larici-populina, the first tree pathogen sequenced, was made publicly available in 2008. Poplar leaf rust outbreaks weaken poplar trees, a candidate bioenergy feedstock whose genome sequence was published by the DOE JGI in… [Read More]

Comparative genomics of social amoebae

Found in soils worldwide, slime molds such as Dictyosteliumdiscoideumare perhaps best known by their behaviors in the presence or absence of food. When food is plentiful, the social amoeba behave as individuals, but when food is scarce, they come together to form multicellular “fruiting bodies” that look like a flower bud atop a single stalk… [Read More]

Arabidopsis lyrata reference genome now available

Arabidopsis thaliana is a small flowering plant often used as a model system by researchers. As part of the 2006 Community Sequencing Program portfolio, the DOE JGI selected A. thaliana’s close relative A. lyrata for sequencing. By comparing their genomes and the genomes of other, related species, researchers could gain insight into plant genetics, specifically… [Read More]

Aureococcus genome project in Knoxville News Sentinel

The research team’s study focused on one particular strand of harmful algal blooms: Aureococcus anophagefferens. Originally, the team thought this strand would be found in the deep oceans, but the researchers discovered instead that it actually thrived in the human-affected conditions of the coastal regions.

Toward a Genomic Encyclopedia of Fungi

Fungi are key components of terrestrial ecosystems and help maintain the interactions between a myriad of species of animals, plants and bacteria that make up these environments. With the ability to thrive in a wide variety of ecological niches, fungi are essential to the global carbon cycle, and the enzymes and metabolites they produce are… [Read More]
