The role of the cytoskeletal proteins MreB and FtsZ in multicellular cyanobacteria. [PDF]

FEBS Open Bio, 2020
Among the myriad of cyanobacterial shapes and sizes, Stigonematales show the highest complexity as they present different cell shapes and sizes within a single cyanobacterial strain. By studying the main cytoskeletal components in these cyanobacteria, we aim to understand how cells undergo these changes. We provide the first insights on the role of the

Taxonomic History and State of Knowledge of the Marine Species in Nostocales (Cyanoprokaryote) From the Mexican Atlantic. [PDF]

Ecol Evol
In this manuscript we contribute a revision of Cyanoprokaryotes Nostocales in the Gulf of Mexico and the Mexican Caribbean; the list of species was updated taxonomically. Also, the historical analysis of their taxonomy was carried out. ABSTRACT Cyanoprokaryotes are organisms that perform oxygenic photosynthesis.

Salinity-driven ecology and diversity changes of heterocytous cyanobacteria in Australian freshwater and coastal-marine microbial mats. [PDF]

Environ Microbiol, 2022
Abstract N2‐fixing heterocytous cyanobacteria are considered to play a minor role in sustaining coastal microbial mat communities developing under normal marine to hypersaline conditions. Here, we investigated microbial mats growing under different salinities from freshwater mats of Giblin River (Tasmania) to metahaline and hypersaline mats of Shark ...

Molecular characterization of two cyanobacterial generitypes from their type localities in Scandinavia. [PDF]

J Phycol
Abstract Over 400 cyanobacterial genera have been described up to the present. Since the Cambridge Rules (https://www.iapt‐taxon.org/historic/1935.htm: Rendle 1935), a type species (generitype) must be specified at the time of description for a new genus to be validly described.

Current and Historical Resource Nitrogen Supply Affects the Eco-Physiological Traits and the Ionome of a Diazotrophic Cyanobacterium. [PDF]

Ecol Lett
Diazotrophic cyanobacteria can overcome nitrogen (N)‐limitation by fixing atmospheric N2; however, this comes with increased energetic, iron, molybdenum, and boron costs. Here, we examined the changes in pigment concentrations, N‐storage, and the ionome of the freshwater diazotroph Dolichospermum flosaquae adapted to an N‐gradient for two temporal ...

Cooperative Biocatalysis Enables Assembly of a Prenylated Indole Alkaloid

Advanced Synthesis &Catalysis, Volume 365, Issue 24, Page 4520-4526, December 19, 2023., 2023
Abstract The hapalindole‐type metabolites have garnered significant interest due to their diverse biological activities and unique chemical structures. Recently, the biosynthesis of this family of indole alkaloids has been uncovered and shown to involve a rare biocatalytic Cope rearrangement. Previously, we demonstrated cis‐indole isonitrile C‐3 normal

Increasing Microcystis cell density enhances microcystin synthesis: a mesocosm study [PDF]

, 2012
An experimental protocol using mesocosms was established to study the effect of Microcystis sp. cell abundance on microcystin production. The mesocosms (55 L) were set up in a shallow eutrophic lake and received either no (control), low (to simulate a ...

Cyt c6-3: A new isoform of photosynthetic Cyt c6 exclusive to heterocyst-forming cyanobacteria [PDF]

, 2017
All known cyanobacteria contain Cyt c6, a small soluble electron carrier protein whose main function is to transfer electrons from the Cyt b6 f complex to PSI, although it is also involved in respiration.
