Metabolite diversity among representatives of divergent Prochlorococcus ecotypes [PDF]
mSystems, 2023 The euphotic zone of the surface ocean contains distinct physical-chemical regimes that vary in light and nutrient concentrations as an inverse function of depth.

Transcriptional Mechanisms of Thermal Acclimation in Prochlorococcus
mBio, 2023 Prochlorococcus is a major marine primary producer with a global impact on atmospheric CO2 fixation. This cyanobacterium is widely distributed across the temperate ocean, but virtually absent at latitudes above 40° for yet unknown reasons.

Understanding opposing predictions of Prochlorococcus in a changing climate
Nature Communications, 2023 This work explains how the spatial structuring of populations, focusing on the globally dominant phytoplankton Prochlorococcus , can lead to erroneous statistical predictions for changes in plankton abundance as the ocean warms.

Snowball Earth, population bottleneck and Prochlorococcus evolution [PDF]
Proceedings of the Royal Society B: Biological Sciences, 2021 Prochlorococcus are the most abundant photosynthetic organisms in the modern ocean. A massive DNA loss event occurred in their early evolutionary history, leading to highly reduced genomes in nearly all lineages, as well as enhanced efficiency in both ...

Linking pangenomes and metagenomes: the Prochlorococcus metapangenome
PeerJ, 2018 Pangenomes offer detailed characterizations of core and accessory genes found in a set of closely related microbial genomes, generally by clustering genes based on sequence homology. In comparison, metagenomes facilitate highly resolved investigations of

Minimal cobalt metabolism in the marine cyanobacterium Prochlorococcus [PDF]
Proceedings of the National Academy of Sciences, 2020 Significance Photosynthetic phytoplankton are the foundation of marine ecosystems. Their growth in the sunlit ocean depends on ample supply of over a dozen essential elements.

Unlocking the Genomic Taxonomy of the Prochlorococcus Collective [PDF]
Microbial Ecology, 2020 Prochlorococcus is the most abundant photosynthetic prokaryote on our planet. The extensive ecological literature on the Prochlorococcus collective (PC) is based on the assumption that it comprises one single genus comprising the species Prochlorococcus ...

Co-culture and biogeography of Prochlorococcus and SAR11 [PDF]
The ISME Journal, 2018 Prochlorococcus and SAR11 are among the smallest and most abundant organisms on Earth. With a combined global population of about 2.7 × 1028 cells, they numerically dominate bacterioplankton communities in oligotrophic ocean gyres and yet they have never

Physiology and evolution of nitrate acquisition in Prochlorococcus [PDF]
The ISME Journal, 2014 Prochlorococcus is the numerically dominant phototroph in the oligotrophic subtropical ocean and carries out a significant fraction of marine primary productivity.

Coexistence of Photosynthetic Marine Microorganisms, Viruses and Grazers: Towards Integration in Ocean Ecosystem Models. [PDF]
Environ MicrobiolOur study explores coexistence regimes of a virus and a zooplankton with a single phytoplankton for different model structures (left panel). The inclusion of an infected class and a resistant class is sufficient to generate coexistence regimes (middle panel). Using algebraic solutions, we optimise our model emphasising the importance of including viral
