Photosynthetic, nitrogen-fixing Anabaena strains are native to tropical paddy fields and
contribute to the carbon and nitrogen economy of such soils. Genetic engineering was …

Calcium ions are important to some prokaryotic cellular processes, such as heterocyst
differentiation of cyanobacteria. Intracellular free Ca2+ concentration,[Ca2+] i, increases …

Various species of cyanobacteria, diatoms and dinoflagellates are capable of synthesizing
the non‐proteinogenic neurotoxic amino acid β‐N‐methylamino‐L‐alanine (BMAA), which …

Channels that cross cell walls and connect the cytoplasm of neighboring cells in
multicellular cyanobacteria are pivotal for intercellular communication. We find that the …

Spatial periodic signal for cell differentiation in some multicellular organisms is generated
according to Turing's principle for pattern formation. How a dividing cell responds to the …

The heterocyst is a specialized cell for nitrogen fixation in some filamentous cyanobacteria.
Here we report that a rubrerythrin (RbrA) from Anabaena sp. PCC 7120 functions as a …

HetR is an essential regulator of heterocyst development in cyanobacteria. HetR binds to a
DNA palindrome upstream of the hetP gene. We report the crystal structure of HetR from …

Summary Filamentous, N2‐fixing, heterocyst‐forming cyanobacteria grow as chains of cells
that are connected by septal junctions. In the model organism Anabaena sp. strain PCC …

The patS gene encodes a small peptide that is required for normal heterocyst pattern
formation in the cyanobacterium Anabaena sp. strain PCC 7120. PatS is proposed to control …

Upon nitrogen starvation, filamentous cyanobacteria develop heterocysts, specialized cells
devoted to the fixation of atmospheric nitrogen. Differentiation of heterocyst at semi‐regular …
