    Scientists find great diversity, novel molecules in microbiome of tree roots

      Diverse communities of microbes in and around poplar tree roots produce a variety of unique natural products.

    Researchers with the Department of Energy’s Oak Ridge National Laboratory have discovered that communities of microbes living in and around poplar tree roots are ten times more diverse than the human microbiome and produce a cornucopia of novel molecules that could be useful as antibiotics, anti-cancer drugs, or for agricultural applications.

    The study marks the first deep look at gene clusters in the Populus microbiome that code for the production of unique and varied natural products.

    Microbes use natural products primarily as signals to communicate with other microbes or with the host plant. These molecules can trigger bacteria to grow, change, or slow their development. As competition for key resources can be fierce, microbes also secrete natural products as antibiotics to eliminate competitors.

    The specific nature of these antibiotics, which often target select bacteria, makes them attractive candidates for use as targeted medicines that could kill the harmful species rather than a broad swath of microbes in a particular community, such as the human gut. The findings provide a starting point for exploring natural products and lay the groundwork for further investigation into the role these molecules play in plant-microbe interactions.

    “We are focused on the exchange of energy, information, and materials across the plant-microbe interface,” said Mitch Doktycz, lead for the Plant-Microbe Interfaces (PMI) Scientific Focus Area at ORNL. “Natural products are key to the performance and health of microbes and their host plants.”

    In surveying the breadth and diversity of natural products and the genetic underpinnings of the microbes producing them, the researchers found an abundance of gene clusters that do not fit into known groups. Almost 15 percent of the gene clusters do not fall into common structural categories. Of the clusters that do fit into known groups, only one percent match sequences that have been previously characterized.

    Rooting out natural products

    “That is a lot of biosynthetic potential,” researcher Patricia Blair said. “Some of the unique gene sequences may code for known natural products. Some may code for molecules we’ve never seen before.”

    The research team conducted computational analysis of more than 300 bacterial genome sequences along with metagenomic samples from dozens of locations. This wealth of genomic information was gathered through previous ORNL research under PMI. The recent paper, published in mSystems, marks the first time many of these bacterial genomes have been described, although the sequences are regularly made available through the Joint Genome Institute.

    At ORNL, these findings will guide ongoing research into the ways plants and microbes interact and influence each other’s survival in the wild. In particular, researchers will be studying the effects of specific natural products and producers on constructed plant community dynamics.

    “Some bacteria are just rife with these gene clusters,” Blair said. “Scientists could prioritize a strain of bacteria or a class of natural products for further study based on these data. There is so much information contained in a single genome, that you just need a place to start.”

    Coauthors on the paper titled, “Survey of the biosynthetic potential of the Populus microbiome,” include Miriam Land, Marek Piatek, Daniel Jacobson, Tse-Yuan Lu, and Dale Pelletier.

    This research was supported through the DOE Office of Science, Biological and Environmental Research Office. The Joint Genome Institute, a DOE Office of Science User Facility, contributed by sequencing microbial genomes and metagenome samples.

    ORNL is managed by UT-Battelle for DOE’s Office of Science. The Office of Science is the single largest supporter of basic research in the physical sciences in the United States, and is working to address some of the most pressing challenges of our time.

    New research identifies causes for defects in 3D printing and paves way for better results

    New research, led by teams from Carnegie Mellon University and the U.S. Department of Energy's (DOE) Argonne National Laboratory, has identified how and when tiny gas pockets in manufactured products, which lead to cracks and other failures, form. The team has also developed a methodology to predict their formation - information that could dramatically improve the 3D printing process.

    Correlated Nucleons May Solve 35-Year-Old Mystery

    A careful re-analysis of data taken at the Department of Energy's Thomas Jefferson National Accelerator Facility has revealed a possible link between correlated protons and neutrons in the nucleus and a 35-year-old mystery. The data have led to the extraction of a universal function that describes the EMC Effect, the once-shocking discovery that quarks inside nuclei have lower average momenta than predicted, and supports an explanation for the effect. The study has been published in the journal Nature.
