Cpf1(Cas12a)-based genome editing in the filamentous cyanobacterium Nostoc punctiforme

This study develops Cpf1-based genome editing tools for Nostoc punctiforme, enabling rapid generation of isogenic mutants with optimized homology arms and cloning strategies.

Diel expression dynamics in filamentous cyanobacteria

This study examines diel expression dynamics in Nostoc punctiforme, revealing circadian regulation of photosynthesis, DNA repair, and mobile genetic elements.

Cyanoexosortase B is essential for motility, biofilm formation and scytonemin production in a filamentous cyanobacterium

This study shows that cyanoexosortase B (CrtB) is essential for motility, biofilm formation, and scytonemin production in Nostoc punctiforme.

The role of FraI in cell-cell communication and differentiation in the hormogonia-forming cyanobacterium Nostoc punctiforme

This study identifies FraI as a protein essential for nanopore formation in septal junctions, which are critical for cell-cell communication and differentiation in Nostoc punctiforme hormogonia.
