Advances in the interactions between marine picocyanobacteria and heterotrophic bacteria

, 2022
Algae-bacteria interaction is among the key areas in marine ecology. Marine picocyanobacteria are ubiquitous primary producers in the aquatic habitat; they play vital roles in global carbon cycles and microbial food webs.

Prochlorococcus Cells Rely on Microbial Interactions Rather than on Chlorotic Resting Stages To Survive Long-Term Nutrient Starvation

mBio, 2020
Many microorganisms produce resting cells with very low metabolic activity that allow them to survive phases of prolonged nutrient or energy stress. In cyanobacteria and some eukaryotic phytoplankton, the production of resting stages is accompanied by a ...

The impact of temperature and photosynthetically active radiation on the growth and pigments concentration in Baltic picocyanobacterium Synechococcus sp.

Annales Universitatis Paedagogicae Cracoviensis Studia Naturae, 2017
The experiments on three Baltic picocyanobacterial strains of Synechococcus (BA-120 – red strain, BA-124 – green strain and BA-132 – brown strain) were conducted at four scalar irradiances in Photosynthetically Active Radiation (PAR) and four temperature

Spatiotemporal diversity and community structure of cyanobacteria and associated bacteria in the large shallow subtropical Lake Okeechobee (Florida, United States)

Frontiers in Microbiology, 2023
Lake Okeechobee is a large eutrophic, shallow, subtropical lake in south Florida, United States. Due to decades of nutrient loading and phosphorus rich sediments, the lake is eutrophic and frequently experiences cyanobacterial harmful algal blooms ...

Allelopathic effect of the Baltic picocyanobacterium Synechococcus sp. on selected diatoms

Annales Universitatis Paedagogicae Cracoviensis Studia Naturae, 2017
It is commonly believed that the structure of phytoplankton and the formation of cyanobacterial and algal blooms may be explained by allelopathic interactions.

Trait‐based responses of nitrogen‐fixing cyanobacteria to nitrogen limitation and light availability: Insights from 45 years of monitoring

Limnology and Oceanography, Volume 71, Issue 8, August 2026.
Abstract The degree to which N2‐fixation compensates for reduced external nitrogen loading has significant implications for eutrophication recovery. We analyzed 45 years of monitoring data from the shallow, polymictic Lake Müggelsee during which external P‐ and N‐loading declined by about 80% and there were extended periods of N‐limitation in summer ...

Nitrogen and Phosphorus Controls on Phytoplankton Growth and Bacterioplankton Communities in Wetland Impoundments

Freshwater Biology, Volume 71, Issue 8, August 2026.
ABSTRACT Nutrient enrichment in shallow lakes and ponds can shift systems from clear water, macrophyte dominance to turbid, phytoplankton dominance. Because the identity and threshold of the limiting nutrients vary among sites, system‐specific evidence is needed to guide water quality management. We conducted 3‐day in situ nutrient‐enrichment bioassays

Testing for the Presence of Photobionts in Eucypris virens (Crustacea: Ostracoda) Green Valves

Freshwater Biology, Volume 71, Issue 8, August 2026.
ABSTRACT Crustaceans exhibit a wide range of organic pigments with different colorations and functions. However, little is known about the origin and function of the characteristic green pigmentation that podocopid ostracods, and in particular Eucypris virens, exhibit in their valves.

Phycobilisomes: modular light‐harvesting systems of cyanobacteria and red algae

The Plant Journal, Volume 127, Issue 3, August 2026.
SUMMARY Phycobilisomes (PBSs) are supramolecular pigment–protein complexes that function as the principal light‐harvesting antennae in cyanobacteria, red algae (Rhodophyta), and glaucophytes, and to a lesser extent in cryptophytes. Because the intrinsic chlorophyll‐based antennae of the photosystems absorb poorly in the green region of the spectrum ...

Diversity and phylogeny of Baltic Sea picocyanobacteria inferred from their ITS and phycobiliprotein operons [PDF]

, 2008
Picocyanobacteria of the genus Synechococcus span a range of different colours, from red strains rich in phycoerythrin (PE) to green strains rich in phycocyanin (PC).
