Giant phytoplankton revealed by in situ imaging

Limnology and Oceanography Letters, Volume 11, Issue 5, September 2026.
Abstract Deployment of an autonomous Zooglider in the western Mediterranean Sea revealed the presence of long phytoplankton chains attaining maximum lengths of 6.4–10.4 mm suspended in situ. Elongate chains included the diatoms Guinardia, Proboscia, two other diatom morphologies, and solitary filaments of the cyanobacterium Trichodesmium. Most elongate

Evolutionary insights into bilin biosynthesis: Functional characterization of pre‐PcyA enzymes

Protein Science, Volume 35, Issue 9, September 2026.
Abstract Biosynthesis of the linear tetrapyrrole phycocyanobilin (PCB) by the ferredoxin‐dependent bilin reductase (FDBR) PcyA is essential for light‐harvesting and regulatory processes in diverse photosynthetic organisms, yet its evolutionary origins are not fully understood. PcyA evolved from pre‐PcyA proteins found in diverse bacteria.

Removal of Photosystem I Subunit PsaE Leads to Photosynthetic Hydrogen Production in a Cyanobacterial PsaF‐HoxYH Fusion Strain

Plant, Cell &Environment, Volume 49, Issue 9, Page 6850-6858, September 2026.
ABSTRACT Photosynthetic hydrogen (photoH2) production is a promising approach for the utilisation of solar energy. Fusion of a hydrogenase (H2ase) to photosystem I (PSI) provides a direct light‐driven route for photoH2 generation. We established the lateral transmembrane subunit PsaF of PSI as a new fusion partner for the NiFe‐hydrogenase (HoxYH) in ...

Determination of Intracellular Osmolytes in Cyanobacterial Cells

Bio-Protocol, 2018
Most of the cyanobacteria accumulate osmolytes including sucrose, glucosylglycerol, in their cells in response to salt stress. Here we describe a protocol of our laboratory for extraction and quantification of cyanobacterial intracellular sucrose and ...

Genome Manipulation in Microalgae: A Systematic Map on Improved Traits, Strains, and Their Commercial Applications

Reviews in Aquaculture, Volume 18, Issue 4, September 2026.
ABSTRACT Microalgae are promising platforms for producing diverse biocompounds relevant to multiple commercial sectors, and the use of genomic technologies in microalgae is rapidly expanding. To examine the research trends, we conducted a bibliographic analysis (systematic map) of this rapidly developing field. Our study presents a descriptive overview

Extraction and Quantification of Alkanes in Cyanobacteria

Bio-Protocol, 2015
Many species of cyanobacteria accumulate alkanes in their cells. It has been reported that these cyanobacteria accumulate mainly 15 long carbon chain alkane, pentadecane (C15H32), or/and 17 long chain alkane, heptadecane (C17H36).

The (Glg)ABCs of cyanobacteria: modelling of glycogen synthesis and functional divergence of glycogen synthases in Synechocystis sp. PCC 6803

FEBS Letters, Volume 600, Issue 15, Page 2175-2192, August 2026.
We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.

AscF in the mycobacterial CIII–CIV supercomplex lacks metal and nucleotide binding but links malate oxidation to respiration

FEBS Letters, Volume 600, Issue 15, Page 2129-2142, August 2026.
The mycobacterial CIII‐CIV respiratory supercomplex is an obligate assembly, encompassing several subunits of unknown functions. We have characterized the intracellular subunit AscF, and show that it is unlikely to be a sensor for metals or nucleotides, but is required for growth on nonfermentable energy sources, and likely works as an adapter for ...

Why a Chloroplast Needs Its Own Genome Tethered to the Thylakoid Membrane—Co‐Location for Redox Regulation

BioEssays, Volume 48, Issue 8, August 2026.
A schematic outline of chloroplast DNA tethered to two stacked thylakoids that contain the components of photosynthetic electron transport. Green shapes represent proteins encoded in chloroplast DNA; brown shapes represent proteins encoded in the cell nucleus. ABSTRACT A chloroplast is a subcellular organelle of photosynthesis in plant and algal cells.
