Interplays between cyanobacterial blooms and antibiotic resistance genes

Environment International, 2023
Cyanobacterial harmful algal blooms (cyanoHABs), which are a form of microbial dysbiosis in freshwater environments, are an emerging environmental and public health concern. Additionally, the freshwater environment serves as a reservoir of antibiotic resistance genes (ARGs), which pose a risk of transmission during microbial dysbiosis, such as ...

Earlier spring may explain dominance of the slow‐growing dinoflagellate Naiadinium polonicum over the cyanobacterium Microcystis during a heatwave

Journal of Phycology, EarlyView.
Abstract Global warming and extreme weather events have been linked to a rise in cyanobacterial blooms, which threaten water quality and ecosystem services. However, during an extreme hot and dry summer, Microcystis was outcompeted by a dinoflagellate, Naiadinium polonicum, in a drinking water lake in southern Sweden.

Bridging the gap between genomic, phenotypic, and modeling data in picophytoplankton–virus interactions

Journal of Phycology, EarlyView.
Abstract We present a comprehensive synthesis of recent developments in methodological approaches to combine experimental and genomic studies of picophytoplankton–virus interactions. This synthesis will not only enhance our understanding of these relationships but also stimulate new hypotheses for the interpretation of metagenomic data and enrich ...

Crawling under the radar: Two novel Paulinella species expand knowledge about the ecology and evolution of a primary plastid‐containing amoeba lineage

Journal of Phycology, EarlyView.
Abstract The genus Paulinella represents a rare, independent case of primary endosymbiosis, providing a unique system to study the early stages of organelle evolution. Here, we expand current understanding of primary plastid endosymbiosis through the discovery and characterization of two novel photosynthetic amoebae, Paulinella marae sp. nov.

Temporal dynamics, microdiversity, and ecological functions of viral communities during cyanobacterial blooms in Lake Taihu

npj Biofilms and Microbiomes
Harmful cyanobacterial blooms pose severe threats to aquatic ecosystems. Bloom-forming cyanobacteria form cyanobacterial aggregates (CAs) that create a phycosphere supporting diverse microbial interactions.

Critical roles of cyanobacteria as reservoir and source for antibiotic resistance genes

Environment International, 2020
The widespread occurrence of antibiotic resistance genes (ARGs) throughout aquatic environments has raised global concerns for public health, but understanding of the emergence and propagation of ARGs in diverse environmental media remains limited.

Controlling cyanobacterial harmful blooms in freshwater ecosystems [PDF]

Microbial Biotechnology, 2017
Summary Cyanobacteria's long evolutionary history has enabled them to adapt to geochemical and climatic changes, and more recent human and climatic modifications of aquatic ecosystems, including nutrient over‐enrichment, hydrologic modifications, and global warming.

Embryonal degreening and seed longevity require plastid LEA proteins

New Phytologist, EarlyView.
Working model of how plastidial LEA proteins aid the remodelling of photosynthetic structures during degreening of Arabidopsis seed embryos. LEA42 and LEA48 support thylakoid proteostasis and membrane remodelling in embryonal cells during late seed maturation by maintaining a local physicochemical environment compatible with protein turnover and ...

Using metabarcoding and droplet digital PCR to investigate drivers of historical shifts in cyanobacteria from six contrasting lakes

Scientific Reports, 2022
The frequency and intensity of cyanobacterial blooms is increasing worldwide. Multiple factors are implicated, most of which are anthropogenic. New Zealand provides a useful location to study the impacts of human settlement on lake ecosystems.

Reversal of a cyanobacterial bloom in response to early warnings. [PDF]

Proc Natl Acad Sci U S A, 2017
Significance Blooms of cyanobacteria in lakes and reservoirs cause fish kills and pose toxicity risk for humans, livestock, and wildlife. Theory suggests that blooms may be anticipated in advance by calculating resilience indicators using high-frequency observations of pigments in lake water.
