Cover Story: Microbial processes are difficult to study in natural soil, owing to the small spatial scales on which microorganisms operate and to the opacity and chemical complexity of the soil habitat. To circumvent these challenges, we have developed synthetic soil aggregates (SSAs), 3D-bioprinted habitats that mimic aspects of natural soil aggregates and provide a chemically defined and translucent culturing method for soil microorganisms. We demonstrate the printability of several microorganisms within SSAs and show how individual SSAs can be integrated into multi-omics workflows and biogeochemical assays. SSAs have the potential to help researchers to quantify microbial processes in situ and achieve high-resolution data from the interplay between environmental properties and microbial ecology.

Zam Is a Redox-Regulated Member of the RNB-Family Required for Optimal Photosynthesis in Cyanobacteria

  • Patrick E. Thomas,
  • Colin Gates,
  • William Campodonico-Burnett and
  • Jeffrey C. Cameron

The zam gene mediating resistance to acetazolamide in cyanobacteria was discovered thirty years ago during a drug tolerance screen. We use phylogenetics to show that Zam proteins are distributed across cyanobacteria and that they form their own uniqu...

The Gut Microbiota May Affect Personality in Mongolian Gerbils

  • Lin Gan,
  • Tingbei Bo,
  • Wei Liu and
  • Dehua Wang

The “gut–microbiota–brain axis” reveals that gut microbiota plays a critical role in the orchestrating behavior of the host. However, the correlation between the host personalities and the gut microbiota is still rarely known....

Root-Associated Bacteria Are Biocontrol Agents for Multiple Plant Pests

  • Jang Hoon Lee,
  • Anne J. Anderson and
  • Young Cheol Kim

Biological control is an important process for sustainable plant production, and this trait is found in many plant-associated microbes. This study reviews microbes that could be formulated into pesticides active against various microbial plant pathog...
