    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.

2021 JGI Proposal Call Brings New Investigators into Community Science Program

Accepted proposals emphasize JGI interests in algae and secondary metabolites.

A total of 27 proposals have been approved through the annual Community Science Program (CSP) call of the U.S. Department of Energy (DOE) Joint Genome Institute (JGI), a DOE Office of Science User Facility located at Lawrence Berkeley National Laboratory (Berkeley Lab). The accepted proposals come from 80 full proposals, resulting from 95 letters of intent. For the first time, 63 percent of the accepted proposals come from investigators who have not previously been a principal investigator (PI) on an approved JGI proposal.

Approved proposals make use of JGI’s breadth of capabilities while also highlighting collaborative research of a scale exceeding a single lab’s capacity. Additionally, the call recommended including plans to analyze and distribute data through the DOE Systems Knowledgebase (KBase), a free, open source data science platform that allows users to explore data and share reproducible analyses with collaborators and the broader community.

The approved proposal from Alex Harkess of Auburn University started as a small-scale white paper focused on duckweed through the CSP New Investigator call. It is the first project to have successfully evolved into a full-scale proposal known as the Brassicales Genome Initiative. Brassicales is represented by more than 4,700 species, and the proposal focuses on investigating the repeated evolution of three traits relevant to DOE interests: photosynthetic transitions, specialized metabolites, and woodiness.

A proposal from Ben Shen of The Scripps Research Institute (TSRI) launches a collaborative effort between JGI, TSRI and the University of Minnesota to establish the Natural Products Genomics Resource Center. To help enable the discovery of secondary metabolites, also referred to as natural products, the proposal includes plans to sequence several thousand Actinobacteria strains and then use computational tools to analyze biosynthetic gene clusters and then develop them for a range of applications. (Hear Ben Shen here in the JGI Natural Prodcast podcast.)

Several accepted proposals reflect JGI’s interest in algal research for bioenergy production and algae’s roles in nutrient cycling, now a facet of the Fungal & Algal Program. For example, green algae represent the largest group of primary producers generating organic compounds through photosynthesis, but only a fraction have been sequenced. Adriana Lopes dos Santos from Singapore’s Nanyang Technological University aims to generate genome sequences from underrepresented green algae groups in a wide range of environments. A similar proposal focused on diatom genomes from Thomas Mock of the University of East Anglia was also approved to learn more about the roles of diatoms in carbon fixation and in aquatic food webs. Finally, Debashish Bhattacharya of Rutgers University is interested in understanding how unicellular red algae (Cyanidiophyceae) have adapted thrive in environments including hot springs and acid mining sites, traits that might have biotechnological applications.

Among the other accepted proposals:

  • Amanda Hurley and Jo Handelsman of the Wisconsin Institute for Discovery (WID) are interested in sequencing secondary metabolite-producing environmental bacteria from the Tiny Earth collection. The work builds upon a pilot project to sequence antimicrobial-producing strains. Established by Handelsman, Tiny Earth aims to crowdsource antimicrobial discovery for the control of plant pathogens, partnering with 600 instructors worldwide who work with more than 10,000 undergraduate students each year.
  • Brian Looney of Duke University is interested in understanding which species of mycorrhizal fungi are important for poplar plant health, in part to learn how these species can modulate their behavior in the presence of other fungi. Poplar is a JGI Flagship Plant, of interest as a candidate bioenergy feedstock.
  • John McKay of Colorado State University is interested in developing mutant populations of the bioenergy feedstock crop Camelina sativa, and generating their genome sequences to improve breeding by genetic improvements.
  • Apomixis is asexual reproduction through seeds, and Peggy Ozias-Akins from the University of Georgia is interested sequencing relatives of switchgrass that are apomictic. This trait would be beneficial for reproduction of improved heterozygous clones through seed.
  • Eric Wommack of the University of Delaware is interested in learning how environmental conditions influence viral-host interactions in three groups: cyanophages, bacteriophages, and giant algal viruses.

The approved proposals started October 1, 2020 and the full list is available here. They are expected to generate publicly available data relevant to DOE interests in finding solutions to energy and environmental challenges, and be of use to the larger research community.
