Ancient Truncated FtsZ Paralogs Likely Tune Cell Division in Hyphomicrobiales

The paper identifies FtsZ paralogs in Hyphomicrobiales, showing they may fine-tune cell division, with FtsZ1 inhibiting division when overexpressed in Agrobacterium tumefaciens.

Activation of the ChvG-ChvI pathway promotes multiple survival strategies during cell wall stress in Agrobacterium tumefaciens

This study identifies how the ChvG-ChvI pathway in Agrobacterium tumefaciens promotes survival under cell wall stress through exopolysaccharide production, beta-lactamase activity, and outer membrane remodeling.

Essentiality of LD-Transpeptidation in Agrobacterium tumefaciens

This study identifies the essential role of LD-transpeptidation in Agrobacterium tumefaciens cell wall integrity and growth by analyzing LDTs and their genetic interactions.

The Cell Division Protein FzlA Performs a Conserved Function in Diverse Alphaproteobacteria

This paper shows that FzlA, an FtsZ-binding protein, conserves its function in activating FtsWI and coordinating chromosome segregation with cell division in diverse alphaproteobacteria.

Activation of SEDS-PBP cell wall synthases by an essential regulator of bacterial division

This study identifies FzlA as a regulator linking FtsZ to PG synthesis during bacterial division, showing it activates and spatially orients division-specific PG synthases.
