Genomic mechanisms for cold tolerance and production of exopolysaccharides in the Arctic cyanobacterium Phormidesmis priestleyi BC1401 [PDF]

open access: yes, 2016
BACKGROUND: Cyanobacteria are major primary producers in extreme cold ecosystems. Many lineages of cyanobacteria thrive in these harsh environments, but it is not fully understood how they survive in these conditions and whether they have evolved ...

Comparative Genomic Analysis Identifies FleQ and GcbB as Virulence‐Associated Factors in Pseudomonas syringae pv. tabaci Strains

open access: yesMolecular Plant Pathology, Volume 26, Issue 11, November 2025.
Comparative genomic analysis between highly virulent strain Pta6605 and less virulent strain Pta7375 showed that point mutations in fleQ and gcbB are responsible for the contrasting virulence‐related phenotypes between the two strains. ABSTRACT Pseudomonas syringae pv.

Efficient Enzymatic Production of the Bacterial Second Messenger c-di-GMP by the Diguanylate Cyclase YdeH from E. coli [PDF]

open access: yes, 2018
Cyclic di-GMP (c-di-GMP) is an almost universal bacterial second messenger involved in the regulation of cell surface-associated traits and the persistence of infections.

A Two‐Protein Chemoreceptor Complex Regulates Oxygen Thresholds in Bacterial Magneto‐Aerotaxis

open access: yesAdvanced Science, Volume 12, Issue 34, September 11, 2025.
Magnetotactic bacteria align with Earth's magnetic field, helping them migrate toward low‐oxygen environments. This study reveals how Magnetospirillum gryphiswaldense uses a specialized flavin adenine dinucleotide (FAD)‐dependent chemoreceptor, composed of two interacting proteins, for precise navigation in oxygen gradients.

Population Genomics of Microbial Biostalactites: Non-recombinogenic Genome Islands and Microdiversification by Transposons

open access: yesFrontiers in Microbiology, 2022
Intrapopulation genetic variability in prokaryotes is receiving increasing attention thanks to improving sequencing methods; however, the ability to distinguish intrapopulation variability from species clusters or initial stages of gene flow barrier ...

Two Decades of Optogenetic Tools: A Retrospective and a Look Ahead

open access: yesAdvanced Genetics, Volume 6, Issue 3, September 2025.
Optogenetics provides up to millisecond scale, cell type‐specific control of biology using light‐sensitive proteins. This review chronicles two decades of tool development, from microbial rhodopsins and photoactivated enzymes to allosteric switches, surveys broad applications in neuroscience, molecular and cell biology, cardiology, immunology, and ...

Identification of a Diguanylate Cyclase and Its Role in Porphyromonas gingivalis Virulence [PDF]

open access: yesInfection and Immunity, 2014
ABSTRACT Porphyromonas gingivalis is a Gram-negative obligate anaerobic bacterium and is considered a keystone pathogen in the initiation of periodontitis, one of the most widespread infectious diseases. Bacterial bis-(3′-5′) cyclic GMP (cyclic di-GMP [c-di-GMP]) serves as a second messenger and is involved in ...

Adenylate cyclase A acting on PKA mediates induction of stalk formation by cyclic diguanylate at the Dictyostelium organizer [PDF]

open access: yes, 2017
Coordination of cell movement with cell differentiation is a major feat of embryonic development. The Dictyostelium stalk always forms at the organizing tip, by a mechanism that is not understood. We previously reported that cyclic diguanylate (c-di-GMP),

Engineering of 1,4‐Butanediol and Adipic Acid Metabolism in Pseudomonas taiwanensis for Upcycling to Aromatic Compounds

open access: yesMicrobial Biotechnology, Volume 18, Issue 8, August 2025.
Growth of an aromatics‐overproducing Pseudomonas taiwanensis on adipate and 1,4‐butanediol was engineered for bio‐upcycling. Adaptive laboratory evolution followed by genome sequencing was used to identify and reverse engineer growth‐enabling mutations.
