    The Mobilome in the Mire

    For years, researchers have known that many datasets miss a key part of microbial genomes: the mobile genetic elements, or MGEs, that can move between organisms. But now, deep sequencing and new analysis methods are bringing this mobilome into light, and opening up new options for engineering these microbes in the future. Join Sarah Bagby (Case Western Reserve University) and Simon Roux (JGI) as they talk about their recent work on a time series from Sweden’s Stordalen Mire.  Nature Microbiology: Mobile genetic elements shape microbial diversity and functions in thawing permafrost soils Episode chapters: 0:00 Intro 4:10 Meet our researchers, and MGEs 6:34 The galaxy of possibilities that MGEs open 8:15 Why MGEs have escaped analysis before 11:06 How a long time series gives a clearer look at MGEs 14:10 Stordalen Mire, a dynamic sample site 17:37 What they did, and what they saw  25:47 Pieces — like the JGI’s sequencing support — that enabled this 28:55 How this work fits in with JGI’s upcoming projects 31:39 Next questions they’d like to answer Another episode on a time series: The Megadata of Lake Mendota — Part 3: Boating Out to David Buoy Submit your own proposal to work with the JGI: http://jointgeno.me/proposals  Episode Transcript: https://jgi.doe.gov//user-science/podcasts/mobilome-mire Our contact info: jgi-comms at lbl dot gov

  2. SIPs with Standards

    SIPs with Standards

    Stable Isotope Probing (SIP) is a powerful technique for studying microbial communities. These experiments can show which microbes are handling specific nutrients, or what they're doing with those nutrients, and even how quickly. But there's a catch: SIP labwork and analysis can be very demanding.  The JGI offers SIP analysis to make these experiments accessible to more researchers. Ultimately, the goal is to generate SIP data that can be useful to multiple teams and analyses. This episode, Rex Malmstrom (JGI), and Roli Wilhelm (Purdue University), share a few different ways they're working to make this technique, SIP, more standardized -- more reproducible, more reusable, and more insightful, for the future of studying microbial communities.

    Adopt-A-Genome

    In this episode, undergraduates adopt genomes that the JGI sequenced, but never published in the literature. These students analyze the genomes, write reports, and publish first-author papers, making the data available for future research.  Hear from Rekha Seshadri (JGI) and Matt Escobar (California State San Marcos) about how the Adopt-A-Genome project got started. Plus, Kalyani Maitra (California State Fresno) and two students, Angela and Mark Soghomonian share what it was like to take on one of these genomes.

    Gotta Catch 'Em Gall

    Kasey Markel and Patrick Shih (UC Berkeley and the Joint BioEnergy Institute) are looking for new ways to engineer plants. So they’ve looked into wasps that program oak trees to grow structures called galls. In this episode, hear from Kasey and Patrick about how this project unfolded, and how they worked with the JGI's metabolomics program to find out more about these weird little pods.

    A Redesign for Yeast’s Genome, Chromosome by Chromosome - Jef Boeke, Weimin Zhang & Leslie Mitchell

    To engineer yeast to do more, and understand genomes in general, Jef Boeke, Weimin Zhang (NYU Langone Health) and Leslie Mitchell (Neochromosome) have worked to replace yeast’s native chromosomes with synthetic versions. This project has turned out to be an international collaboration, with some artistic endeavors along the way. Eventually, the goal is to create an entirely human-generated yeast genome.

    What Happens To a Rainforest When You Dial Up Drought? - Linnea Honeker and Malak Tfaily

    Rainforests store a big fraction of all the carbon on Earth, and soil microbes play a key role in pulling that carbon out of the atmosphere. This episode, researchers take a look at what happens to that storage when a rainforest hits a drought. Tag along with their experiments in a fully enclosed, human-made ecosystem: Biosphere 2.  Links from this episode: Submit your own proposal to work with the JGIJoin us at the 2024 JGI User MeetingFICUS program Find all episode transcripts on our websitePaper: Drought re-routes soil microbial carbon metabolism towards emission of volatile metabolites in an artificial tropical rainforest  https://doi.org/10.1038/s41564-023-01507-7 Our contact info:Twitter: @JGIEmail: jgi-comms at lbl dot gov

    The Megadata of Lake Mendota - Part 3: Boating Out to David Buoy

    This is the third and final episode of our series on a giant metagenome assembly from Wisconsin’s Lake Mendota. In the last two episodes, we’ve covered the specialized software and supercomputers behind this project. But every part of this project depends on lakewater samples — so this episode is a look at how researchers get these specialized snapshots of a freshwater ecosystem.
