Genomic analysis of self-fertilizing fungi

Filamentous fungi help decay plant material, a process which has applications for producing biofuels and other products. The model organism for filamentous fungi is Neurospora tetrasperma. Neurospora tetrasperma rosette (Image by Namboori B. Raju, Stanford University) Selected for the DOE JGI’s 2007 Community Sequencing Program, the fungi is of interest to researchers such as studying… [Read More]

DOE JGI’s Tringe in PopSci’s Brilliant 10

Susannah Green Tringe of the DOE Joint Genome Institute (DOE JGI) has been named one of 2011’s “Brilliant 10,” the annual list compiled by Popular Science magazine of top young researchers. In adding her name to the list, which appears in the October issue, the magazine recognized her $2.5 million grant from the DOE Early… [Read More]

Soil biocrust microbial genome

One of the DOE JGI’s 2011 Community Sequencing Program projects involves studying biological soil crusts to understand their role in the global carbon cycle. Found in arid lands which make up nearly half of the planet’s total land mass, communities of lichens, mosses and cyanobacteria use soil particles to form biocrusts less than half an… [Read More]

High-temperature enzymes for biomass breakdown

To overcome the challenge of breaking down cellulosic biomass for commercial biofuel production, which involves the application of high temperatures, a team of researchers including DOE JGI’s Martin Allgaier, now at the Leibniz-Institute of Freshwater Ecology and Inland Fisheries in Germany, and Phil Hugenholtz, now director of the Australian Centre for Ecogenomics at the University… [Read More]

Dry rot (Serpula) genome project in BasqueResearch.com

Science journal has published research work on the sequence of the genome of the Serpula lacrymans fungus and in which the Public University of Navarre (UPNA) lecturers Gerardo Pisabarro de Lucas and José Antonio Oguiza Tomé, professor and senior lecturer in Microbiology respectively, participated. The research, largely funded by the US Department of Energy through… [Read More]

Dark ocean project in Climate Action

To understand the world’s climate, we must understand how the 70% of the Earths surface that is covered with water behaves. Very little is known about the processes below 200m, or the area where photosynthesis is not possible due to the lack of light penetration. Scientists from the U.S. Department of Energy Joint Genome Institute… [Read More]

A mechanism for de novo intron insertion

Introns are the parts of a gene sequence that are not expressed in the protein. In the August 30 issue of Nature Communications, a team led by DOE JGI’s Eukaryote Program head Dan Rokhsar and Uffe Hellsten describe a potential mechanism by which introns have been added to a genome sequence since what they refer… [Read More]

A “meraculous” way to conduct whole-genome assemblies

The dramatic shift in sequencing technologies that allows genome researchers to generate the equivalent of a single human genome in days rather than the decades it took multiple organizations to complete a single one has also shifted the bottleneck from sequence production to sequence assembly. For example, the Sanger platform routinely produced reads 700 basepairs… [Read More]

DOE JGI’s Prochnik in Discovery News

“This one-celled organism hunts and eats bacteria as an amoeba, swims around looking for a better environment as a flagellate, and then hunkers down and waits for good times as a cyst,” said Simon Prochnik, a computational scientist at the U.S. Department of Energy’s Joint Genome Institute. “It is a very rare process to go… [Read More]
