Bacterial Communities Associated With Spherical Nostoc Macrocolonies [PDF]

Frontiers in Microbiology, 2019
Species of the genus Nostoc (Cyanobacteria) can form large colonies of up to several centimeters in diameter that may represent a unique habitat for bacteria in freshwaters. Bacteria inside the colony are probably segregated from the surrounding water and largely dependent on the metabolism of this primary producer. However, the existence of a specific

Symbiotic Versatility in Action: Trebouxia Diversity Expands the Niche of the Lichen Xanthoria parietina

Environmental Microbiology, Volume 28, Issue 7, July 2026.
Xanthoria parietina associates with an unexpectedly high diversity of Trebouxia phycobionts within clade A across the Mediterranean Basin. Climatic niche modelling reveals that differences in photobiont climatic preferences contribute to symbiont switching and help explain the broad ecological amplitude and geographic success of this widespread lichen.

Abundance, Diversity and Metabolomic Profiles of Soil Cyanobacteria‐Dominated Microbial Communities Under Long‐Term Differential Management in an Olive Orchard

Environmental Microbiology, Volume 28, Issue 7, July 2026.
Sustainable management in a semi‐arid olive orchard increased abundance and diversity of nitrogen‐fixing cyanobacteria, shifting dominance towards Nodosilinea and Nostoc, while conventional soils were dominated by Leptolyngbya. Metabolomics showed stress‐related lipid and vitamin production under conventional management versus enhanced amino acids and ...

Phylogenetic evaluation of the genus Nostoc and description of Nostoc neudorfense sp. nov., from the Czech Republic

International Journal of Systematic and Evolutionary Microbiology, 2020
Cyanobacterial strain ARC8 was isolated from seepage coming into the river Dračice, Františkov, Czech Republic, and was characterized using a polyphasic approach. Strain ARC8 showed a typical Nostoc -like morphology and in-depth morphological characterization ...

Water Availability and Air Humidity Strongly Affect Photosynthesis in Biofilms on Tree Trunks: Predictions for a Climate‐Changing World

Environmental Microbiology, Volume 28, Issue 7, July 2026.
Photosynthetic behaviour in cyanobacteria‐dominated biofilms on tree bark is very sensitive to water availability and vulnerable to climatic changes. ABSTRACT Climate change intensifies drought in several regions. Here, we assess how water availability and air humidity regulate photosynthesis in epiphytic cyanobacterial biofilms on Jacaranda ...

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.

Influence of cyanobacterial auxin on sprouting of taro (Colocasia esculenta var. antiquorum) and corm yield

The Indian Journal of Agricultural Sciences, 2017
Cyanobacteria are widely exploited in wet land rice cultivation as biofertilizer. Apart from nitrogen fixation, cyanobacteria are capable of producing a number of plant growth promoting substances.

Corn response to biological products and a nitrification inhibitor

Agrosystems, Geosciences &Environment, Volume 9, Issue 2, June 2026.
Abstract Atmospheric nitrogen (N2) is converted into ammonia (NH3), a form that plants can use, through biological nitrogen (N) fixation by various microorganisms and bacterial genera. This study assessed the field performance of three biological N‐fixing products, or biostimulants (BS), including Gluconacetobacter diazotrophicus (BS1), Klebsiella ...

The Nostoc punctiforme Genome [PDF]

, 2001
Nostoc punctiforme is a filamentous cyanobacterium with extensive phenotypic characteristics and a relatively large genome, approaching 10 Mb. The phenotypic characteristics include a photoautotrophic, diazotrophic mode of growth, but N. punctiforme is also facultatively heterotrophic; its vegetative cells have multiple development alternatives ...

Oxylipin formation in Nostoc punctiforme (PCC73102)

Phytochemistry, 2007
The dioxygenation of polyunsaturated fatty acids is mainly catalyzed by members of the lipoxygenase enzyme family in flowering plants and mosses. Lipoxygenase products can be metabolized further and are known as signalling substances that play a role in plant development as well as in plant responses to wounding and pathogen attack.
