Marine and giant viruses as indicators of a marine microbial community in a riverine system [PDF]

open access: yes, 2016
Viral communities are important for ecosystem function as they are involved in critical biogeochemical cycles and controlling host abundance. This study investigates riverine viral communities around a small rural town that influences local water inputs.

Grazing preferences of three species of amoebae on cyanobacteria and green algae

open access: yesJournal of Eukaryotic Microbiology, Volume 71, Issue 2, March/April 2024.
Abstract Twenty species/isolates of cyanobacteria and green algae were isolated from cyanobacterial bloom samples in lakes associated with the upper Qu'Appelle River drainage system in southern Saskatchewan, Canada. Three amoebae species (Cochliopodium sp., Vannella sp.

Prevalence and evolution of core photosystem II genes in marine cyanobacterial viruses and their hosts.

open access: yesPLoS Biology, 2006
Cyanophages (cyanobacterial viruses) are important agents of horizontal gene transfer among marine cyanobacteria, the numerically dominant photosynthetic organisms in the oceans.

Temporal transcriptional patterns of cyanophage genes suggest synchronized infection of cyanobacteria in the oceans

open access: yesMicrobiome, 2020
Background Based on the peak expression times during infection, early, middle, and late genes have been characterized in viruses (cyanophages) that infect the unicellular cyanobacterium Prochlorococcus.

Physical measures to inhibit planktonic cyanobacteriae [PDF]

open access: yes, 1992
In a small lake, intermittent destratification was installed after several other physico-chemical and physical in-lake therapy measures (phosphorus immobilization, permanent destratification) had been tested without great success.

Lake browning counteracts cyanobacteria responses to nutrients: Evidence from phytoplankton dynamics in large enclosure experiments and comprehensive observational data

open access: yesGlobal Change Biology, Volume 30, Issue 1, January 2024.
The combined impacts of multi‐stressors on phytoplankton remain difficult to predict. We combined large enclosure experiments with a comprehensive time‐series and a broad‐scale field survey to unravel the effects of storm‐induced lake browning, nutrient enrichment and deep‐mixing on phytoplankton communities, focusing on potentially toxic ...

Differences in cyanophage and virioplankton production dynamics in eddies of opposite polarity in the North Pacific Subtropical Gyre

open access: yesFrontiers in Marine Science
Viruses are abundant in the ocean and influence both the composition of marine communities and biogeochemical cycles. Despite their high abundance, production rates of distinct virus taxa in the environment are largely unknown.

Expanding the toolbox for phycobiliprotein assembly: phycoerythrobilin biosynthesis in Synechocystis

open access: yesPhysiologia Plantarum, Volume 176, Issue 1, January/February 2024.
Abstract Phycobiliproteins (PBPs) play a vital role in light harvesting by cyanobacteria, which enables efficient utilization of photon energy for oxygenic photosynthesis. The PBPs carry phycobilins, open‐chain tetrapyrrole chromophores derived from heme. The structure and chromophore composition of PBPs is dependent on the organism's ecological niche.

Single cells and microcolonies of freshwater picocyanobacteria: a common ecology [PDF]

open access: yes
Picocyanobacteria (Pcy) single-cells and microcolonies are common in lakes throughout the world, and abundant across a wide spectrum of trophic conditions.
