The Role of Rhizobacterial Exopolysaccharides in Plant Growth Promotion and Abiotic Stress Resistance: A Review

Many microorganisms, including Plant Growth-Promoting Rhizobacteria (PGPR), are capable of synthesizing exopolysaccharides (EPS) and excreting them as either soluble or insoluble polymers.

To Move or Not to Move: When and How Bacteria Suppress Flagellar Motility

Molecular Microbiology, EarlyView.
Motility cessation in bacteria is a key regulatory strategy that provides multiple survival advantages including enhanced community cooperation, niche adaptation and evasion of host immune responses. This process is controlled by associated mechanisms such as post‐translational modifications and second messenger signalling that stabilise non‐motile ...

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

Molecular Microbiology, EarlyView.
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 ...
