A review of studies to better understand effects of climate change on microbial activities. The Science: Researchers are harnessing strategies including metagenomics to learn more about the microbial communities in permafrost and their current and potential responses to climate change. The Impact: Researchers estimate that permafrost covers a quarter of the plant’s land area, and… [Read More]

Fungal genome offers insights into growing crops in salty environments. The Science: Researchers sequenced and analyzed the genome of an extremophilic fungus that has adapted to thrive in the Dead Sea. The Impact: The genome provides information on how the fungus can tolerate extremely salty conditions. As climate change continues to affect agricultural lands and… [Read More]

Functional annotation reveals novel biomass-degrading enzymes from microbial genomes. The Science: Functional annotation allowed researchers to identify biomass-degrading enzymes in the 35 percent of genes in a genome that are considered “genomic dark matter.” The Impact: Identifying 17 putative biomass-degrading cellulases from the content of more than 5,500 microbial genomes is of use to bioenergy… [Read More]

Single cell genomics reveals diversity of cyanobacteria subpopulations. The Science: Single cell genomics allowed researchers to examine the subpopulations of the marine microbe Prochlorococcus, affording a glimpse at “a new dimension of microdiversity.” The Impact: The cyanobacterial subpopulations were found to be distinct, comprised of “genomic backbones” made of highly conserved core gene alleles and… [Read More]

Detailed protocol outlines steps for extracting ample DNA from uncultured microbes. The Science: Characterizing uncultured microbes starts with isolating and sequencing enough DNA from an environmental sample that may be as small as a single cell. The Impact: The protocol has been successfully employed to amplify the genomes of 201 single cells from uncultured microbes… [Read More]

Researchers employ RNA-Seq techniques to improve annotations for analysis. The Science: A team of researchers from the U.S. Department of Energy Joint Genome Institute (DOE JGI), the University of California, Berkeley, and the Great Lakes Bioenergy Research Center generated an ultra-deep, high quality transcriptome–the fraction of the genome that provides information about gene activity–of maize….

Recently sequenced microbes living in Deep Lake are mostly specialists, cornering different niches in the lake ecosystem The Science: Four microbes dominate in the Antarctica’s Deep Lake, making up 70% of the microbial community. They belong to a group called haloarchaea that require high salt concentrations to grow and are naturally adapted to extreme conditions… [Read More]

Medical compounds harvested from a marine sponge are actually produced by symbiotic bacteria living in the sponges. The Science: The research team used single-cell genome analysis, and metagenomic sequencing to find that just two bacterial tenants of a marine sponge, Theonella swinhoei, make medically important compounds called polyketides. Both bacteria belong an uncultivated genus, Enthotheonella. The research… [Read More]

The recently sequenced genome of Spirodela polyrhiza showcases why the plant makes an excellent raw source for biofuels. The Science: Duckweed is one of the smallest and fastest-growing flowering plants that can be a hard-to-control weed in ponds and small lakes. Sequencing the genome of Greater Duckweed (Spirodela polyrhiza) has provides clues about how the tiny… [Read More]
