The projects of 13 Biosciences Area scientists and engineers received funding through the FY18 Laboratory Directed Research and Development (LDRD) program. These projects span a diverse array of topics and approaches including the study of microbiomes in relation to patterns of mutualism, crop productivity, and gut health; synthetic biology for engineering biosurfactant production and energy conversion pathways; and the application of technologies such as machine learning, high-resolution optical microscopy, and single-cell transcriptomics. Together, these efforts account for 18.75 percent of the $20 million allocated. Lab-wide, 74 projects were selected from a field of 215.
Northen Lab Publishes Video Protocol for Building EcoFABs
Scientists in Trent Northen’s groups in Environmental Genomics and Systems Biology (EGSB) and Metabolomics Technology at the DOE Joint Genome Institute (JGI) have published detailed video protocols for creating fabricated ecosystems, or EcoFABs, in the Journal of Visualized Experiments (JOVE). These laboratory-scale controlled habitats, constructed using widely available 3D printing technologies, enable mechanistic studies of plant-microbe interactions within specific environmental conditions. The published protocols serve as a starting point for other researchers, ideally helping to create standardized experimental systems for investigating plant-microbe interactions. The video component of this article can be found here.
Area Scientists to Present Talks at 2018 AAAS Annual Meeting
Several Berkeley Lab scientists will present talks at the 72nd annual meeting of the American Association for the Advancement of Science (AAAS), the world’s largest general scientific society, to be held February 15 through 19 in Austin, Texas. Among them are four representing the Biosciences Area: Mary Maxon, Blake Simmons, Trent Northen, and Susannah Tringe.
Microbial Metabolism in Real World Native Biocrusts
Biological soil crusts, or biocrusts, contain communities of microorganisms—including fungi, bacteria, and archaea—that dwell together within the uppermost millimeters of soil in arid lands. These microbes can exist for extended periods in a desiccated, dormant state, becoming metabolically active when it rains. Understanding how biocrust microbial communities adapt to their harsh environments could help shed light on the roles of soil microbes in the global carbon cycle. Berkeley Lab scientists led by Trent Northen’s group in Environmental Genomics and Systems Biology (EGSB) found that specific compounds are transformed by and strongly associated with specific bacteria in native biological soil crust. The researchers reported their findings in a paper published January 2 in Nature Communications.
State Assembly Member Tim Grayson Visits Joint Genome Institute
Grayson (D-Concord) and his district director Naser Javaid recently visited JGI to learn about their sequencing, metabolomics, single-cell genomics, and DNA synthesis capabilities. Grayson also met with JGI Director Nigel Mouncey and heard from researchers Susannah Tringe and Trent Northen.
