    Data yielded from RIViT-seq increased the number of sigma factor-gene pairs confirmed in Streptomyces coelicolor from 209 to 399. Here, grey arrows denote previously known regulation and red arrows are regulation identified by RIViT-seq; orange nodes mark sigma factors while gray nodes mark other genes. (Otani, H., Mouncey, N.J. Nat Commun 13, 3502 (2022). https://doi.org/10.1038/s41467-022-31191-w)
    Streamlining Regulon Identification in Bacteria
    Regulons are a group of genes that can be turned on or off by the same regulatory protein. RIViT-seq technology could speed up associating transcription factors with their target genes.

Deepwater Horizon oil spill cleanup microbes project in Examiner.com

The first research effort reported in an article published online June 21, 2012, in the ISME Journal involved samples taken immediately after the Deepwater Horizon spill began and during the ensuing clean up efforts.The researchers found that a variety of microbes consumed parts of the oil spill selectively. Each group of microbes specifically targeted one group of… [Read More]

Deepwater Horizon cleanup microbes project in Oil and GasOnline

To learn more about the microbial community’s response to the oil spill, researchers led by Berkeley Lab senior scientist Janet Jansson availed themselves of the expertise and resources at two of the Lab’s national user facilities, the U.S. Department of Energy Joint Genome Institute (DOE JGI) and the Advanced Light Source (ALS). The work done… [Read More]

Permafrost metagenome study on VOA Special English report

The researchers say one gram of the soil could contain thousands of different kinds of microbes and billions of cells. They say these organisms had never before been cultured in a laboratory. JANET JANSSON:  “So more than ninety percent of those bacteria and other microorganisms in permafrost, we had no idea what they were.” Read… [Read More]

Permafrost soil metagenome study in Wired UK

As permafrost thaws, trapped frozen organic matter becomes accessible for microbes to degrade, releasing greenhouse gases as a byproduct. Understanding what sorts of microbes are in the ice is key to predicting the impact of the melting of permafrost soils.The US Department of Energy has teamed up with the Joint Genome Institute, the Earth Sciences Division of… [Read More]

Permafrost soil metagenome study on Voice of America

Lead author Janet Jansson, senior scientist at the Lawrence Berkeley National Laboratory in California says the trapped microorganisms in permafrost are still active. Jansson and colleagues at the U.S. Geological Survey and the Joint Genome Institute at the Department of Energy set out to identify microbes in permafrost and find out what they would do once… [Read More]

Permafrost soil metagenome study on Medill News Reports

Microbes frozen for thousands of years can spring to life and digest the carbon to release heat-trapping gases into the atmosphere, amplifying warming and melting. Scientists can’t yet predict how much of the carbon stored in Arctic permafrost will reach the atmosphere, but microbes could play a pivotal role. Read more on Medill Reports Chicago [Read More]

Permafrost soil metagenome study in Time

One of those wild cards is the 1,672 billion tonnes of carbon equivalent trapped in the form of methane in the Arctic permafrost, the soils kept frozen by the far North’s extreme temperatures. Methane is a powerful greenhouse gas—it has 20 times the warming effect of carbon dioxide—and the total amount of carbon equivalent in… [Read More]

Permafrost soil metagenome study on LiveScience

“Nobody has looked at what happens to microbes when the permafrost thaws,” said Janet Jansson, a senior staff scientist at Lawrence Berkeley National Laboratory in California. She led a study that recorded what happened when chunks of Alaskan permafrost thawed for the first time in 1,200 years. Read more on LiveScience [Read More]

Permafrost soil metagenome study in UK Press Association

At the testing laboratories, US researchers extracted almost 40 billion elements of raw DNA, reflecting high microbial diversity in the soil.The scientists were also able to piece together the genetic code, or genome, of a previously unknown methane-producing “methanogen” that was present in large numbers. Reporting their findings in an early online edition of the journal… [Read More]

Permafrost soil metagenome study in GenomeWeb

“Currently in climate models, it’s not really taken into account adequately what the microorganisms are doing,” senior author Janet Jansson, a researcher affiliated with the Lawrence Berkeley National Laboratory and the US Department of Energy’s Joint Genome Institute, told GenomeWeb Daily News. “The hope is to get enough information at the microscopic level that we’ll have… [Read More]
