Getting to the Root of a Plant’s Success
Plants are powerful factories – they can turn basic ingredients like carbon dioxide, water, and sunlight into oxygen, sugars, and plant mass. But plants don’t do all of this work on their own. Below the soil’s surface, plant roots work with tiny microbes to gain access to the nutrients they need to survive.
Although Tiny, Peatland Microorganisms Have a Big Impact on Climate
Polyphenols are generally toxic to microorganisms. In peatlands, scientists thought microorganisms avoided this toxicity by degrading polyphenols using an oxygen-dependent enzyme, and thus that low-oxygen conditions inhibit microbes’ carbon cycling.

Surprising Strategies: Scientists Quantify the Activity of Algal-Associated Bacteria at the Microscale
Microalgae in water are responsible for roughly 50% of the photosynthesis that converts carbon dioxide from the atmosphere into organic carbon. Researchers have now quantified the activity in the microbiome associated with these microalgae to investigate how the microbiome’s members process and exchange carbon and nitrogen from algal cells. They used isotopes and high-resolution imaging mass spectrometry to quantify these exchanges at the single-cell level.

Engineering New Metabolic Pathways that Function Across Microbial Kingdoms
Microbes have enormous potential to produce metabolites with potential industrial applications. To do so, microbes use groups of genes called biosynthetic gene clusters (BGCs) that code for the sets of necessary enzymes. Scientists have computationally predicted the products of hundreds of thousands of BGCs, but have experimentally confirmed fewer than 2,000 of them. Researchers have now developed a computational and experimental strategy to redesign BGCs and determine the natural chemical products they create.
Perfect ‘Pathogen’ Storm: Vibrio Bacteria, Sargassum and Plastic Marine Debris
Little is known about the ecological relationship of Vibrio bacteria with Sargassum. Evidence also is sparse as to whether vibrios colonizing plastic marine debris and Sargassum could potentially infect humans. As summer kicks off and efforts are underway to find solutions to repurpose Sargassum, could these substrates pose a triple threat to public health? Results of a study representing the first Vibrio spp. genome assembled from plastic finds Vibrio pathogens have the unique ability to “stick” to microplastics, harboring potent opportunistic pathogens.
Predicting Changes in Microbial Food Webs
Increasing temperature or nutrients in an ecosystem can destabilize food webs, but when temperature and nutrients increase together it can be difficult to predict the combined effects. This study examined a laboratory microbial food web consisting of bacterial prey and protist predators. It found that temperature and nutrients can alter the dynamics of microbial communities by changing how species’ abundances and average body sizes relate to each other.
