Bacterial blooms are characterized by unusually high cell densities and exceptionally low diversity and can profoundly alter ecosystem function and services. Bacteriophages have long been considered an important cause of mortality in blooms, acting as a mechanism for control. Here, we characterize the viral ecology of...

Soil bacteria colonize plants without causing visible disease, yet many suppress host growth. The prevalence and evolutionary reach of this cryptic inhibition are unknown, because phenotyping hundreds of isolates in plants is prohibitively slow. Here we use the unicellular algae Chlamydomonas reinhardtii as a scalable...

Anoxygenic phototrophic green sulfur bacteria (GSB; Chlorobiia) are important primary producers in anoxic and sulfidic environments, whose significance in aquatic ecosystems will expand with coastal deoxygenation. Here, we employed a uniquely comprehensive analytical approach to investigate the formation, maintenance,...

Many animals benefit from microbial symbionts that aid digestion, supply essential nutrients, or provide defense. When this dependence becomes obligate, as in gutless marine oligochaetes that have lost both digestive and excretory systems and rely entirely on their bacterial partners for nutrition and recycling of wast...

TriMic is established, a taxonomically and functionally representative culture collection of wheat root–associated bacteria that includes high quality genome sequences and an overview of genes involved in plant colonization, nutrient cycling, and plant growth promotion and expanded by designing a reduced complexity Syn...

It is revealed that a globally distributed clade of symbiotic SRB has a conserved core metabolism that diverges from free-living relatives, and these endosymbionts retain key traits of SRB such as sulfate reduction, complete oxidation of acetate to CO2, amino acid degradation for nitrogen acquisition, and transport of...

A wide range of microorganisms produce storage biopolymer polyhydroxyalkanoates (sPHAs) as carbon and energy reserves. However, only bacteria and fungi are known to degrade microbial sPHAs, using enzymes called polyhydroxyalkanoate depolymerases (PHADs). Here we show that some animals also have PHADs that can degrade s...
