Survival of Prochlorococcus in extended darkness [PDF]
Limnology and Oceanography, 2016 AbstractProchlorococcus is the smallest oxygenic phototroph in the ocean, where it can be found in great abundance throughout the euphotic zone in mid‐latitude waters. Populations of this picocyanobacterium have been observed below the euphotic zone, but the viability of these cells is unclear.

Diel transcriptional response of a California Current plankton microbiome to light, low iron, and enduring viral infection. [PDF]
, 2019 Phytoplankton and associated microbial communities provide organic carbon to oceanic food webs and drive ecosystem dynamics. However, capturing those dynamics is challenging. Here, an in situ, semi-Lagrangian, robotic sampler profiled pelagic microbes at

Adaptive Evolution of Phosphorus Metabolism in Prochlorococcus [PDF]
mSystems, 2016 Microbes are known to employ three basic strategies to compete for limiting elemental resources: (i) cell quotas may be adjusted by alterations to cell physiology or by substitution of a more plentiful resource, (ii) stressed cells may synthesize high-affinity transporters, and (iii) cells may access more costly sources from internal ...

Presence of Prochlorococcus in the aphotic waters of the western Pacific Ocean [PDF]
, 2014 Prochlorococcus, the smallest but most abundant marine primary producer, plays an important role in carbon cycling of the global ocean. As a phototroph, Prochlorococcus is thought to be confined to the euphotic zone, with commonly observed maximum depths

Prochlorococcus extracellular vesicles: molecular composition and adsorption to diverse microbes
bioRxiv, 2020 Extracellular vesicles are small (~50–200 nm diameter) membrane-bound structures released by cells from all domains of life. While vesicles are abundant in the oceans, our understanding of their functions, both for cells themselves and the emergent ...

The Distinctive Regulation of Cyanobacterial Glutamine Synthetase [PDF]
, 2018 Glutamine synthetase (GS) features prominently in bacterial nitrogen assimilation as it catalyzes the entry of bioavailable nitrogen in form of ammonium into cellular metabolism. The classic example, the comprehensively characterized GS of enterobacteria,
