Cyanobacteria as multifunctional bioinputs for sustainable intensification, soil health enhancement, and climate resilience in rice‐based cropping systems

Agrosystems, Geosciences &Environment, Volume 9, Issue 1, March 2026.
Abstract Ensuring food security goals through the provision of sustainable energy and food without compromising environmental sustainability is the current requirement amid threats from climate change, uncontrolled global population, and scarcity of natural resources.

Manipulation of Pattern of Cell Differentiation in a hetR Mutant of Anabaena sp. PCC 7120 by Overexpressing hetZ Alone or with hetP

Life, 2018
In the filamentous cyanobacterium, Anabaena sp. PCC 7120, single heterocysts differentiate at semi-regular intervals in response to nitrogen stepdown. HetR is a principal regulator of heterocyst differentiation, and hetP and hetZ are two genes that are ...

Functional dissection and evidence for intercellular transfer of the heterocyst‐differentiation PatS morphogen [PDF]

Molecular Microbiology, 2013
SummaryThe formation of a diazotrophic cyanobacterial filament represents a simple example of biological development. In Anabaena, a non‐random pattern of one nitrogen‐fixing heterocyst separated by about 10 photosynthetic vegetative cells results from lateral inhibition elicited by the cells differentiating into heterocysts. Key to this process is the

Ecological, Functional, and Phylogenetic Determinants of Cyanobacterial Biomineralisation

Environmental Microbiology Reports, Volume 18, Issue 1, February 2026.
Cyanobacteria contribute to the global carbon cycle by biomineralising CO2 into solid carbonates. Unlike photosynthesis, biomineralisation is a less‐understood, multifaceted and adaptive metabolic process with significant global impact. It involves cell wall structures, genetic factors, and metabolic pathways that enable mineral formation and help ...

Rapid Transcriptional Reprogramming Triggered by Alteration of the Carbon/Nitrogen Balance Has an Impact on Energy Metabolism in Nostoc sp. PCC 7120

Life, 2020
Nostoc (Anabaena) sp. PCC 7120 is a filamentous cyanobacterial species that fixes N2 to nitrogenous compounds using specialised heterocyst cells.

Evolution of molecular communication in the permanent Azolla symbiosis

New Phytologist, Volume 249, Issue 4, Page 1666-1674, February 2026.
Summary Heritable symbioses exist across eukaryotes with different degrees of intimacy. In most cases, the symbionts are obligate and require inheritance for their survival. On the host side, symbiont retention can facilitate fitness benefits. Only rarely are these symbioses interwoven to the point that host survival relies on the symbiont.

Cyanobacteria and Cyanotoxins in Mediterranean Reservoirs: Ecological Variability, Risks and Implications for Water Quality Assessment

Ecohydrology, Volume 19, Issue 1, January‐February 2026.
ABSTRACT The increasing demand for freshwater, in combination with climate change and pollution, compromises the quality and quantity of water resources. These pressures have intensified cyanobacterial blooms, including toxic events that threaten human health and aquatic ecosystems. This study complements the objectives of the Water Framework Directive

Expanding the Role of FurA as Essential Global Regulator in Cyanobacteria.

PLoS ONE, 2016
In the nitrogen-fixing heterocyst-forming cyanobacterium Anabaena sp. PCC 7120, the ferric uptake regulator FurA plays a global regulatory role. Failures to eliminate wild-type copies of furA gene from the polyploid genome suggest essential functions. In

Phylogeny‐Aware Metabologenomics Accurately Assigns Natural Products to Biosynthetic Gene Clusters

Microbial Biotechnology, Volume 19, Issue 1, January 2026.
We report a statistical approach for associating biosynthetic gene clusters with their cognate metabolites and demonstrate its unprecedented power for scalable natural product discovery. Notably, it drastically reduces spurious associations by explicitly integrating the phylogeny of microbial producer strains.
