Selaginella genome project on NPR

Probing the secrets of plants at the genetic level is all the rage these days among scientists seeking to understand how plants evolved on Earth. One of those plants is selaginella, one of the first plants to develop a system of tubes that transport water and nutrients inside a plant. Read more or listen to… [Read More]

Selaginella genome project in GenomeWeb Daily News

By sequencing the genome of the spikemoss Selaginella moellendorffii and comparing it to several other sequenced plant genomes, researchers have identified genetic patterns that correspond to different stages of plant evolution. Read more at GenomeWeb Daily News [Read More]

Poplar leaf rust genome project in GenomeWeb Daily News

By comparing the genomes to one another and to some previously sequenced fungal pathogens and symbionts, the researchers identified features in the rust fungi genomes that seem to coincide with their pathogenic lifestyles. For instance, they tracked down a slew of genes coding for so-called effectors — small, secreted proteins that help the fungi thwart… [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]

First analysis of Trichoderma species as biocontrol agents

Trichodermaatroviride and T. virens are filamentous fungi commonly found in the soil and are good at protecting crops such as beans, tomatoes, strawberries and cotton against a range of fungal pathogens. Their ability to do so could offer bioenergy crop growers an alternative to chemical pesticide treatment. Both were selected for sequencing by the DOE… [Read More]

Finding cellulases in sediment from a paper mill

During the DOE JGI User Meeting held in Walnut Creek, Calif. from March 22-24, 2011, collaborator Daniel Distel noted that more than 20 enzymes are needed to break down cellulose. To assist in identifying novel cellulose degraders and thus improve cellulosic biofuel production processes, a team of DOE JGI researchers including Microbial Program head TanjaWoyke… [Read More]

Phil Hugenholtz on metagenomics and ecogenomics in Australian Life Scientist

In research published in Nature in 2007, Hugenholtz, along with collaborators from the California Institute of Technology and Diversa (now Verenium) Corporation, used metagenomics to detail the process by which a dry wood feeding termite, a Nasutitermes species, breaks down cellulose.  They generated 62 million base pairs – a “drop in the ocean by today’s… [Read More]

UCLA team makes isobutanol from cellulose on ScienceDaily

While there were many possible microbial candidates, the research team ultimately chose Clostridium cellulolyticum, which was originally isolated from decayed grass. The researchers noted that their strategy exploits the host’s natural cellulolytic activity and the amino acid biosynthetic pathway and diverts its intermediates to produce higher alcohol than ethanol. The researchers also noted that Clostridium… [Read More]

DOE JGI’s microbial work and IMG on ESNet’s Network Matters

Microbes are single-cell organisms that live in colonies and can be found in nearly every corner of our planet, in places ranging from insects’ intestines to some of the most toxic chemical environments. The site for the most detailed information on the genetic makeup of these organisms only lives in one place – at the… [Read More]

Daphnia pulex, the first crustacean genome

A keystone species in freshwater ecosystems, the water flea Daphnia pulex, is roughly the size of the equal sign on a keyboard. In the February 4 issue of Science, the nearly decade-long collaboration between the Daphnia Genomics Consortium and the DOE JGI culminated with a report on this first crustacean genome. “Daphnia is one of… [Read More]
