In filamentous cyanobacteria, the mechanism of gliding motility is undefined but posited to be driven by a polysaccharide secretion system known as the junctional pore complex (JPC). Recent evidence implies that the JPC is a modified type IV pilus‐like structure encoded for in part by genes in the hps locus. To test this hypothesis, we conducted genetic, cytological and comparative genomics studies on hps and pil genes in Nostoc punctiforme, a species in which motility is restricted to… Expand
Identification of a hormogonium polysaccharide‐specific gene set conserved in filamentous cyanobacteria
TLDR
A co‐occurrence analysis of Hps orthologs among cyanobacteria identified an extended set of putative Hps proteins comprising most components of a Wzx/Wzy‐type polysaccharide synthesis and export system, implying that HPS may be secreted through a more canonical pathway, rather than a T4P‐mediated mechanism. Expand
Dynamic localization of HmpF regulates type IV pilus activity and directional motility in the filamentous cyanobacterium Nostoc punctiforme
TLDR
Results are consistent with a model where direct interaction between HMPF and the T4P system activates pilus extension, the Hmp system facilitates coordinated polarity of HmpF to establish motility, and the Ptx system modulates Hmpf localization to initiate reversals in response to changes in light intensity.

Motility in cyanobacteria: polysaccharide tracks and Type IV pilus motors
TLDR
A new report by Khayatan and colleagues suggests that the motility of Nostoc hormogonia has much more in common with Synechocystis than was previously thought. Expand
A Putative O-Linked β-N-Acetylglucosamine Transferase Is Essential for Hormogonium Development and Motility in the Filamentous Cyanobacterium Nostoc punctiforme
TLDR
Results imply that O-GlcNAc protein modification regulates the accumulation of PilA via a posttranscriptional mechanism in developing hormogonia. Expand
The involvement of type IV pili and phytochrome in gliding motility, lateral motility and phototaxis of the cyanobacterium Phormidium lacuna
Phormidium lacuna, a filamentous cyanobacterium without heterocysts, can be transformed by natural transformation. These filaments are motile on agar and other surfaces and display rapid lateralExpand
A partner‐switching regulatory system controls hormogonium development in the filamentous cyanobacterium Nostoc punctiforme
TLDR
Results support a model where HmpU and HmpW antagonistically regulate the phosphorylation state of HmpV, and subsequently, unphosphorylated HMPV positively regulates an undefined downstream target to affect hormogonium‐specific gene expression. Expand
Type 4 pili are dispensable for biofilm development in the cyanobacterium Synechococcus elongatus
TLDR
Pili are dispensable for biofilm development in this cyanobacterium, in contrast to their biofilm-promoting function in type IV pili-producing heterotrophic bacteria, and it is shown that adhesion and timing ofBiofilm development differ between the piliated and non-piliated strains. Expand
The Role of the Cyanobacterial Type IV Pilus Machinery in Finding and Maintaining a Favourable Environment
TLDR
Type IV pili (T4P) are proteinaceous filaments found on the cell surface of many prokaryotic organisms and convey twitching motility through their extension/retraction cycles, moving cells across surfaces, further cementing the role of cell surface appendages. Expand

TLDR
A comprehensive synthesis of the latest mechanistic and structural data for focal adhesion-mediated gliding motility in M. xanthus is provided, suggesting that gliding and cell envelope synthetic complexes are evolutionarily linked. Expand
Impairment of a cyanobacterial glycosyltransferase that modifies a pilin results in biofilm development
TLDR
It is proposed that the unglycosylated pili facilitate DNA transformation and affects multiple processes including production or secretion of the inhibitor as well as the ability to sense or respond to it. Expand

Comparative transcriptomics with a motility‐deficient mutant leads to identification of a novel polysaccharide secretion system in Nostoc punctiforme
TLDR
The phenotype of inactivation of a methyl‐accepting chemotaxis‐like protein in Nostoc punctiforme, designated HmpD, is reported, found to be essential for hormogonium development, motility and polysaccharide secretion. Expand
Type IV pilus biogenesis and motility in the cyanobacterium Synechocystis sp. PCC6803
TLDR
The PilA1 polypeptide is required for the biogenesis of the thick pilus morphotype which, in turn, is necessary for motility (hence the type IV pili), and two genes encoding proteins with similarity to PilT, which is considered to be a component of the motor essential for type IV pilus‐dependent movement, were inactivated.

TLDR
The phenotype of the deletion strains, and the localization of the Hmp proteins and the putative PilA protein to rings at the cell junctions are consistent with the hypothesis that these proteins are part of the junctional pore complex observed in a number of filamentous cyanobacteria. Expand

The results strongly suggest that slime secretion is not only a prerequisite for this peculiar type of motility in cyanobacteria, but also directly generates the necessary thrust for locomotion. Expand
