Innovative Technology Improves Our Understanding of Bacterial Cell Signaling
Cyclic di-GMP (Guanine Monophosphate) is found in nearly all types of bacteria and interacts with cell signaling networks that control many basic cellular functions. It plays an important role in regulating microbial cellulose production and biofilm formation, which affects a number of environments, including plants, soil, and the gut. To better understand the dynamics of this molecule, researchers developed the first chemiluminescent biosensors for measuring cyclic di-GMP in bacteria through work enabled by the JGI’s Community Science Program (CSP).

Building Sphagnum Genomic Resources
Sphagnum’s impact on global carbon cycling and climate is estimated to be larger than any other single plant genus. Researchers estimate that the peatlands hold about 25 percent of the world’s soil carbon. Enabled by the JGI’s Community Science Program (CSP), researchers are developing a number of resources to build up Sphagnum as a plant model system focused on carbon cycling studies.

Iron-rich Microbial Mats’ Main Players: Marsarchaeota
Through a combination of sequencing tools and techniques applied to samples collected from acidic iron-oxide microbial mats in Yellowstone National Park over time, researchers have discovered and characterized a novel phylum-level lineage of archaea with at least two major subgroups dubbed Marsarchaeota.

Quantifying Cyanobacteria Interactions
The long term objective is to quantify dynamic interactions between phototrophs and their virus predators. This will help to build quantitative, dynamic and predictive models of host-viral interactions and the effect on carbon and nutrient cycling.

DAS Tool for Genome Reconstruction from Metagenomes
Through the JGI’s Emerging Technologies Opportunity Program (ETOP), researchers have developed and improved upon a tool that combines existing DNA sequence binning algorithms, allowing them to reconstruct more near-complete genomes from soil metagenomes compared to other methods. The work was published in Nature Microbiology.
