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]

Sweetening the Biofuels Production Process

Currently, converting cellulosic biomass into biofuels is inefficient and costly.  One of the barriers to reducing costs and yields is that xylose, a five-carbon sugar that represents nearly half of available sugars in plant (in the form of hemicellulose), is extremely difficult and time-consuming to break down using enzymes sourced from conventional yeast strains. In… [Read More]

Dry rot (Serpula) genome on ScienceNewsline

As reported online July 14 in Science Express, an international team of scientists including DOE JGI researchers compared the genome of Serpula lacrymans, the second brown rot fungus to have its genome sequenced, against 10 other published fungal genomes. The DOE JGI sequenced seven of these genomes among them Postia placenta, the first brown rot… [Read More]

Dry rot (Serpula) project in Biofuels Journal

“For example, if you go back far enough in time to the period when trees were developing, there was no way to break lignocellulose down, which led to the coal seams we tap today.“When the fungi figured out how to break down lignocellulose, the coevolution of the fungi and trees kick-started the carbon cycle again.”… [Read More]

Dry rot (Serpula) genome project on Greenwire

Researchers have sequenced the genome for brown rot — also known as dry rot — in a step that could have applications for biofuels and better understanding of forest carbon cycling. Dry rot, a scourge of homeowners, is a fungus that decays wood by attacking its sugars — cellulose and hemicellulose — and working around… [Read More]

Mycosphaerella genome project in Capital Press

Septoria typically infects young seedlings that have recently emerged, creating lesions, and spreading to the higher leaves. It can affect yield and quality, Goodwin said. Control methods are typically fungicide sprays, he noted. Igor Grigoriev, of the U.S. Department of Energy’s Joint Genome Institute in Walnut Creek, Calif., has been sequencing the genomes of other… [Read More]

Mycosphaerella project in Media Newswire

Enzymes often break down plant cell walls and begin removing nutrients, leading to the plant’s death. M. graminicola, however, enters the plant through stomata, small pores in the surface of leaves that allow for exchange of gases and water.  Goodwin said the fungus seems to lay dormant between plant cells, avoiding detection. It later infects… [Read More]

Mycosphaerella genome project in Agricultural Research

The pathogen that causes the disease, Mycosphaerella graminicola, has a long “silent period,” a latent stage during which it takes nutrition from the living plant and evades the host plant’s natural defenses. Scientists previously did not have a good understanding of how the organism infects wheat, or how the wheat plant itself resists the pathogen…. [Read More]

Mycosphaerella genome project in Farmers Guardian

SCIENTISTS have cracked the genetic code of septoria tritici – the most important foliar disease of wheat in the UK – and in doing so have gained an insight into how the disease is able to evade wheat’s natural defences. The researchers, who were funded by the BBSRC and others, hope the study, which reveals… [Read More]

First Finished Filamentous Fungus

An international consortium of scientists, including scientists from DOE JGI, have published the analysis for Mycosphaerella graminicola, the first filamentous fungus to be fully finished. Having the 39.7 million nucleotide genome available will enable researchers to learn more about the methods plant pathogens use to attack and damage crops, including those being considered for use… [Read More]
