Strategies and mechanisms of precision genome engineering: From gene editing to genome writing

iMetaOmics, Volume 3, Issue 3, September 2026.
In this review, we examined the progression of genome manipulation from stochastic nuclease‐mediated cutting toward precise editing and programmable genome writing. We discussed tools like multi‐kilobase RNA‐guided integrators and Artificial Intelligence (AI)‐designed effectors and showed how these advances enable researchers to treat genomes as ...

Serpentine Biocrust Microbes Maintain Nitrogen Cycling Under Drought and Heavy Metal Stress

Ecological Research, Volume 41, Issue 5, September 2026.
This study highlights the complex interplay between soil geochemistry and moisture availability in shaping microbial communities within wetter and drier serpentine and non‐serpentine biological soil crusts. It demonstrates that both factors influence the structure of nitrogen‐cycling microbial communities and the processes they mediate.

Production of cyanobacterial toxins from two Nostoc species (Nostocales) and evaluation of their cytotoxicity in vitro [PDF]

Journal of BioScience and Biotechnology, 2012
Cyanobacteria are among the oldest autotrophic organisms with cosmopolitan distribution and known as producers of secondary metabolites with toxic properties named "cyanotoxins".

Transcript analysis of the extended hyp-operon in the cyanobacteria Nostoc sp. strain PCC 7120 and Nostoc punctiforme ATCC 29133

BMC Research Notes, 2011
Background Cyanobacteria harbor two [NiFe]-type hydrogenases consisting of a large and a small subunit, the Hup- and Hox-hydrogenase, respectively. Insertion of ligands and correct folding of nickel-iron hydrogenases require assistance of accessory ...

Prospection of cyanobacteria producing bioactive substances and their application as potential phytostimulating agents

Biotechnology Reports, 2020
This work clarifies some of the substances involved with the biostimulant effect shown by 28 cyanobacteria isolated from different aquatic environments. The production of salicylic acid, cytokinins, siderophores and phosphate solubilization were analyzed

Adaptation of Microbialite‐Associated Prokaryotic Communities to Natural and Experimental Anoxic Conditions

Geobiology, Volume 24, Issue 5, September/October 2026.
ABSTRACT Microbialites are rocks formed by microbial communities that influence, promote, and/or control the precipitation of mineral phases. The oldest microbialites date back to the Archean and formed under globally anoxic conditions. Accordingly, modern microbialites developing under oxic conditions are limited analogs of their earliest predecessors.

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

Influence of Temperature Variations on Growth of Nostoc (Cyanobacteria) HS-5 and HS-20 Isolated from Indonesian Hot Springs

Microbiology Indonesia, 2018
The research aims to know the effect of variation temperature to the growth of Nostoc HS (Hot Spring)-5 and HS-20. Strain of Nostoc HS-5 was isolated from Ciseeng hot spring which has habitat temperature range of 30-43 °C, and Nostoc HS-20 was isolated ...

A Phosphorylation‐Dependent Partner‐Switching‐Like Module Regulates a Glycosyltransferase Required for Heterocyst Polysaccharide Layer Formation in Anabaena sp. Strain PCC 7120

Molecular Microbiology, Volume 126, Issue 3, Page 237-243, September 2026.
The glycosyltransferase All4160 is regulated by the reversible phosphorylation of Ser74. The kinase Alr3423 phosphorylates and inactivates All4160, while the SpoIIE‐like phosphatase HenR restores its activity through dephosphorylation. A nonphosphorylatable variant of All4160 bypasses the need for HenR, which demonstrates that a phosphorylation ...

Desiccation tolerance mechanisms in the green lineage and beyond

New Phytologist, Volume 251, Issue 6, Page 3159-3175, September 2026.
Ancient origin and recurrent evolution of desiccation tolerance in the green lineage. Summary Water is essential for life on Earth, yet some plants can survive the near‐complete loss of cellular water, a trait known as desiccation tolerance. Although rare in vegetative tissues of vascular plants, desiccation tolerance is scattered across the plant ...
