An updated view on the long‐term survival and significance of marine protist resting stages

Limnology and Oceanography Letters, Volume 11, Issue 4, July 2026.
Abstract Resting stages of protists act as biological time capsules when buried in marine sediments, preserving viable cells that enable the study of ecological and evolutionary processes across timescales. Recent studies have extended the known viability in diatoms to several millennia and in dinoflagellates to over a century, while also identifying ...

Photosynthesis regulation impacts carbon and nitrogen assimilation in the diazotrophic cyanobacterium Anabaena sp. PCC 7120

New Phytologist, Volume 251, Issue 1, Page 94-110, July 2026.
Model of intercellular functional coordination in Anabaena. Summary Diazotrophic cyanobacteria fix both atmospheric carbon (C) and nitrogen (N) into biomass, but the two assimilation pathways are not compatible. Species like Anabaena sp. PCC 7120 physically separate C and N assimilation in different cell types.

Structural proteomics reveals the functional docking interface of ferredoxin‐NADP+ reductase on photosystem I in the red alga Cyanidioschyzon merolae

The Plant Journal, Volume 127, Issue 1, July 2026.
SUMMARY Efficient photosynthetic electron transfer relies on transient interactions between photosystem I (PSI) and soluble electron carriers. However, structural information describing these transient interactions are limited in red algae. Here, we applied chemical cross‐linking mass spectrometry (XL‐MS) to isolated thylakoid membranes of the red alga

Nature's Nanotech Warriors: The Role of Metalloproteins and Protein Cages for Environmental Remediation

Advanced Sustainable Systems, Volume 10, Issue 6, June 2026.
Cartoon representation of five major classes of metalloproteins and their brief mechanisms of bioremediation. The five classes include metallothioneins, metal‐precipitating enzymes, P.‐type ATPases, protein cages, and synthetic metalloproteins (de novo‐designed proteins/peptides for selective adsorption). These natural and engineered protein structures

Cyanobacteria and Fungicide as Controlling Agents for Cotton Fungal Diseases [PDF]

Journal of Agricultural Chemistry and Biotechnology
Biological control is a very important factor as sustainable alternative or complement to conventional pesticides for fungal plant disease management. This study was carried out on cotton plants to investigate the roles of cyanobacteria in controlling ...

Reversible Regime Change: Climate‐Driven Phytoplankton Community Shifts in the Cariaco Basin, Venezuela

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 6, June 2026.
Abstract Phytoplankton communities are integral to oceanic biogeochemical cycles and are sensitive indicators of climate‐driven environmental variability. Long‐term time series capture this variability, allowing us to unravel the effects of environmental change on local communities.

Molecular and phylogenetic characterization of two species of the genus Nostoc (Cyanobacteria) based on the cpcB-IGS-cpcA locus of the phycocyanin operon [PDF]

Journal of BioScience and Biotechnology, 2012
Traditionally, the taxonomy of the genus Nostoc is based on morphological and physiological characters. The extreme morphological variability of the Nostoc species, due to their life cycle and environmental conditions, hampers the correct identification ...

Dominance and toxicity without lethality: Exploring biomass, cyanometabolites, and Daphnia responses across Cyanobacterial strains

Journal of Phycology, Volume 62, Issue 3, Page 801-817, June 2026.
Abstract Cyanobacteria are cosmopolitan, important components of biomass with a remarkable ability to synthesize a diverse array of bioactive compounds, some of which may have toxic effects on other organisms and ecosystems. In this study, filamentous cyanobacterial strains isolated predominantly from temperate European freshwaters (Aphanizomenon ...

Functional and structural insights into cyanobacterial CO2 concentrating mechanisms: from compartmentalization to regulation

The Plant Journal, Volume 126, Issue 5, June 2026.
Significance Statement Life on Earth depends on photosynthetic CO2 fixation via the Calvin–Benson–Bassham cycle to form organic carbon. This process evolved first in cyanobacteria and was later conveyed to eukaryotes, giving rise to plastids in algae and plants. To cope with low atmospheric CO2 concentrations that developed over the course of evolution,

Specific mutations in the permease domain of septal protein SepJ differentially affect functions related to multicellularity in the filamentous cyanobacterium Anabaena

Microbial Cell, 2018
Filamentous, heterocyst-forming cyanobacteria are multicellular organisms in which growth requires the activity of two interdependent cell types that exchange nutrients and regulators.
