Tracing the active genetic diversity of Microcystis and Microcystis phage through a temporal survey of Taihu.

PLoS ONE, 2020
Harmful algal blooms are commonly thought to be dominated by a single genus, but they are not homogenous communities. Current approaches, both molecular and culture-based, often overlook fine-scale variations in community composition that can influence ...

Effects of the cultivable bacteria attached to Microcystis colonies on the colony size and growth of Microcystis [PDF]

Journal of Freshwater Ecology, 2019
The interactions between bacteria and algae may play a significant part in the formation and development of algal blooms. The bloom-forming cyanobacterium Microcystis occurs mainly as colonial form in natural waters, and thus it is necessary to study the

Growth Inhibition of Microcystis Cyanobacteria by L-Lysine and Disappearance of Natural Microcystis Blooms with Spraying

Microbes and Environments, 2004
Low concentrations of L-lysine and L-lysine-containing-peptides strongly inhibited the growth of axenic strains of 4 species belonging to the genus Microcystis (cyanobacteria). Inhibitory activities decreased in the order of L-lysine>tri-L-lysine>di-L-lysine>α-poly-L-lysine>L-lysyl-L-histidine>L-lysyl-L-alanine.

The Complete Genomes of <i>Microcystis ichthyoblabe</i> Kützing and <i>Microcystis protocystis</i> (Crow) Komárek & Anagnostidis Reveal the Complexity and Plasticity of <i>Microcystis</i> Genomes. [PDF]

Microorganisms
Microcystis is a genus of cyanobacteria responsible for harmful algal blooms (HABs) in freshwater ecosystems, posing significant ecological and public health risks. Despite its importance, current genomic resources are heavily biased toward Microcystis aeruginosa, limiting comprehensive understanding of genomic diversity within the genus. In this study,

The genetic and ecophysiological diversity of Microcystis [PDF]

Environmental Microbiology, 2021
SummaryMicrocystis is a cyanobacterium that forms toxic blooms in freshwater ecosystems around the world. Biological variation among taxa within the genus is apparent through genetic and phenotypic differences between strains and via the spatial and temporal distribution of strains in the environment, and this fine‐scale diversity exerts strong ...

The global Microcystis interactome [PDF]

Limnology and Oceanography, 2019
AbstractBacteria play key roles in the function and diversity of aquatic systems, but aside from study of specific bloom systems, little is known about the diversity or biogeography of bacteria associated with harmful cyanobacterial blooms (cyanoHABs). CyanoHAB species are known to shape bacterial community composition and to rely on functions provided

Spatio-Temporal Resolution of Microbial Functions and Taxa Associated With Cyanobacterial Harmful Algae Blooms Along a 500-Km Aquatic Continuum in the Lake Erie Watershed. [PDF]

Environ Microbiol
The aquatic microbiome can influence cyanobacterial harmful algal blooms. Abundances of genes and transcripts for phosphorus acquisition, denitrification and nitrogen fixation were higher upstream, whereas in Lake Erie genes and transcripts for microcystin production were higher.

Colony formation in the cyanobacterium Microcystis [PDF]

Biological Reviews, 2018
ABSTRACTMorphological evolution from a unicellular to multicellular state provides greater opportunities for organisms to attain larger and more complex living forms. As the most common freshwater cyanobacterial genus, Microcystis is a unicellular microorganism, with high phenotypic plasticity, which forms colonies and blooms in lakes and reservoirs ...

Buoyancy Regulation in a Strain of Microcystis [PDF]

Microbiology, 1985
SUMMARY: A strain of the gas-vacuolate cyanobacterium Microcystis was found to float in cultures grown at low light intensities and to sink in those grown at high intensities. The loss of buoyancy that occurred within 1 to 5 h on increasing the photon flux density from 10 to 100 μmol m-2 s-1 was investigated by centrifuging the cell suspensions in a ...
