Photophobotaxis of single‐celled and filamentous cyanobacteria

Photochemistry and Photobiology, EarlyView.
LED illumination from below induces central accumulation of cyanobacterial species. Abstract Phototaxis refers to an organism's movement toward a light source, while photophobotaxis involves movement into illuminated regions. Although phototaxis in cyanobacteria has been widely studied, photophobotaxis has been investigated in only a few species.

Proton gradients during salt adaptation of synechococcus [PDF]

IUBMB Life, 1996
AbstractThe ability of cells to energize their membranes during salt‐adaptation as measured by ΔpH was studied using the electron spin resonance (ESR) spin probe technique. Salt‐adaptated cells have the following features: an increased stability of ΔpH across the cytoplasmic membrane and a significantely lower rate of ΔpH formation across the thylakoid

Advances in large DNA fragment assembly for microbial cell factory engineering

Quantitative Biology, Volume 14, Issue 3, September 2026.
Abstract The efficient, rapid, and reliable assembly of DNA fragments is essential for advancing metabolic engineering and synthetic biology. With the rapid advancement of DNA synthesis and assembly technologies, the scale of DNA assembly has expanded from single genes to metabolic pathways and even genomes.

Assessment of the Allelochemical Activity and Biochemical Profile of Different Phenotypes of Picocyanobacteria from the Genus Synechococcus

Marine Drugs, 2020
Organisms belonging to Synechococcus sp. genera are observed in all freshwater, brackish, and marine waters of the world. They play a relevant role in these ecosystems, since they are one of the main primary producers, especially in open ocean ...

Primary productivity coupled to oxic methane production in coastal waters of southern China

Limnology and Oceanography Letters, Volume 11, Issue 4, July 2026.
Abstract Oxic methane (CH4) production (OMP) occurs in diverse oxygenated surface waters worldwide. However, phytoplankton‐driven OMP in natural marine environments remains poorly documented. During a research cruise in the highly productive southern East China Sea, we measured OMP by incubating phytoplankton‐rich surface waters and found that CH4 ...

Seasonal and spatial variations of Synechococcus in abundance, pigment types, and genetic diversity in a temperate semi-enclosed bay

Frontiers in Microbiology
Synechococcus is abundant and globally widespread in various marine environments. Seasonal and spatial variations in Synechococcus abundance, pigment types, and genetic diversity were investigated based on flow cytometric analysis and high-throughput ...

Deciphering cyanobacterial phenotypes for fast photoautotrophic growth via isotopically nonstationary metabolic flux analysis

Biotechnology for Biofuels, 2017
Background Synechococcus elongatus UTEX 2973 is the fastest growing cyanobacterium characterized to date. Its genome was found to be 99.8% identical to S. elongatus 7942 yet it grows twice as fast.

Physiological and biochemical microcystin-RR toxicity to the Synechococcus elongatus

, 2004
Freshwater Microcystis may form dense blooms in eutrophic lakes. It is known to produce a family of related cyclic hepatopeptides (microcystins, MC) that constitute a threat to aquatic ecosystems.

Chromatic Adaptation in Marine Synechococcus Strains [PDF]

Applied and Environmental Microbiology, 2001
ABSTRACT Characterization of two genetically distinct groups of marine Synechococcus sp. strains shows that one, but not the other, increases its phycourobilin/phycoerythrobilin chromophore ratio when growing in blue light.
