The paper identifies ChiA as the chitinase enzyme responsible for chitin degradation in Synechococcus WH7803 using CRISPR-mediated loss-of-function mutants.

This study profiles metabolite diversity across three Prochlorococcus ecotypes, revealing strain-specific differences in intracellular and extracellular metabolite accumulation and release.

This study shows marine picocyanobacteria utilize chitin, linking their planktonic lifestyle evolution to chitin degradation and ecological expansion.

This paper investigates how environmental and taxonomic factors influence bacterial extracellular vesicle production in marine ecosystems, showing significant variation across species and environmental conditions.

The paper investigates nitrite production and cross-feeding in Prochlorococcus strains during nitrate assimilation, revealing metabolic partnerships that may influence ocean nutrient cycles.

The paper shows that Prochlorococcus in iron-depleted regions uses siderophores for iron uptake, with this trait more common in the North Pacific than the North Atlantic.

The paper identifies tycheposons, mobile genetic elements in Prochlorococcus, that drive genomic plasticity through gene exchange and contribute to microbial adaptation in ocean ecosystems.

This study analyzes the molecular composition of Prochlorococcus extracellular vesicles and their interactions with other microbes, revealing their potential roles in oceanic biogeochemical processes.

This study identifies phosphonate biosynthesis in marine microbes, showing its prevalence in diverse lineages and potential role in reducing grazing and viral mortality.

This study shows Prochlorococcus and Synechococcus can adapt to repeated light deprivation, with an epigenetic mechanism involved, though no DNA methylation was detected in the tested strain.

The paper examines microbial diversity in cultures of marine picocyanobacteria, finding that heterotroph community composition varies with host ecotype and isolation conditions, while some bacteria are consistently abundant.

This paper reports unsuccessful attempts to develop genetic transformation methods for Prochlorococcus and describes progress in optimizing electroporation parameters and protocols for axenic colony formation and cell viability assessment.

The paper investigates the association between lanthipeptide genes and TnpAREP transposases in marine picocyanobacteria, suggesting a potential diversifying recombination mechanism for prochlorosin expansion.

The paper examines mispackaging of Prochlorococcus DNA by three cyanophages, finding distinct frequencies influenced by growth conditions and cellular factors.

The paper examines nitrate assimilation gene distribution across Prochlorococcus genomes to understand evolutionary mechanisms shaping trait variability in microbial species.

This study co-cultures Prochlorococcus and SAR11 isolates to examine their interactions and biogeography, finding SAR11 grows faster with Prochlorococcus but not vice versa, and Prochlorococcus meets SAR11's carbon needs.
