    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.

    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.

    A genetic element that generates targeted mutations, called diversity-generating retroelements (DGRs), are found in viruses, as well as bacteria and archaea. Most DGRs found in viruses appear to be in their tail fibers. These tail fibers – signified in the cartoon by the blue virus’ downward pointing ‘arms’— allow the virus to attach to one cell type (red), but not the other (purple). DGRs mutate these ‘arms,’ giving the virus opportunities to switch to different prey, like the purple cell. (Courtesy of Blair Paul)
    A Natural Mechanism Can Turbocharge Viral Evolution
    A team has discovered that diversity generating retroelements (DGRs) are not only widespread, but also surprisingly active. In viruses, DGRs appear to generate diversity quickly, allowing these viruses to target new microbial prey.

    Yeast strains engineered for the biochemical conversion of glucose to value-added products are limited in chemical output due to growth and viability constraints. Cell extracts provide an alternative format for chemical synthesis in the absence of cell growth by isolating the soluble components of lysed cells. By separating the production of enzymes (during growth) and the biochemical production process (in cell-free reactions), this framework enables biosynthesis of diverse chemical products at volumetric productivities greater than the source strains.

Moss Sequencing “Ennobles” Flagship Genome

Physcomitrella Genome Expected to Provide Help with Global Climate Change

The Science

An international team of scientists has annotated all 32,275 genes of Physcomitrella patens, a moss sequenced by the DOE Joint Genome Institute that contains about 10,000 more genes than humans.

The Impact

It is widely believed that the P. patens genome contains information that will help global environments cope with wide-scale climate change. Researchers in the study were able to provide a functional analysis of these genes.

Summary

The P. patens genome, which was first sequenced by the DOE JGI, provides insights to the study of many biological processes, including the carbon cycle.

The P. patens genome, which was first sequenced by the JGI, provides insights into the study of many biological processes, including the carbon cycle.

P. patens has long been the experimental moss of choice for researchers around the world and was first sequenced by the JGI in 2007. The plant provides insights as to the mechanisms behind plant cell wall synthesis and assembly, mainly due to its accelerated life cycle that allows more comprehensive studies of such processes. In a study published July 23, 2013 in BMC Genomics, the international team – consisting of researchers from Germany, Belgium, and Japan – worked with the genes of what the JGI refers to as a “flagship genome,” a term meaning that sustained and significant computational and experimental resources are directed to this organism. By using the sequencing information from the JGI, the team was able to attribute functions and metabolisms to the P. patens genome.

“One of our intriguing findings is that 13 percent of the Physcomitrella genes have no clear relatives in any other sequenced organism so far. Analyzing these orphan genes more deeply will reveal the hidden treasures of the moss genome,” said the University of Freiburg Chair of Plant Biotechnology Ralf Reski, a senior coordinator on the study, in a statement. The moss genome data are available through the JGI plant portal Phytozome.
