Cross-regulation of (p)ppGpp and c-di-GMP pathways controls a cell-cycle transition

Corentin Jaboulay, Chloé Dugelay, José P.S. Maio, Katell Beillevaire, Philippe Vogeleer, Daniel Vinella, Fabien Létisse, Régis Hallez, Boyuan Wang, Laurent Terradot, Mathilde Guzzo

The paper shows (p)ppGpp inhibits c-di-GMP synthesis in Caulobacter crescentus, linking metabolic stress to developmental arrest through direct molecular interaction.

Stress-Induced Iron-Sulfur Cluster Damage as a Conserved Trigger of the Stringent Response

Eva Michaud, Lorena Ricci, Claire Lallement, Lars Barquist, Vincent Cattoir, Charlotte Michaux, Régis Hallez, Séverin Ronneau

This study identifies Fe-S cluster damage as a trigger of the stringent response in Gram-negative pathogens, linking metabolic stress to virulence and transcriptional control.
