Cell cycle progression and stalked cell morphogenesis in Caulobacter crescentus are regulated independently by the flagellum

This study identifies fss genes that regulate stalked cell morphogenesis and cell cycle progression independently of the flagellum in Caulobacter crescentus.

Adaptation of Methylobacterium extorquens to alternating carbon sources identifies the regulator CstR as an intersectional hub of cellular carbon metabolic dynamics and stress response

This study identifies CstR as a key regulator in Methylobacterium extorquens that coordinates carbon source transitions and stress responses, with loss-of-function mutations improving metabolic flexibility but reducing stress resilience.

Decreasing peptide deformylase activity is a beneficial strategy for increasing formaldehyde resistance in Methylobacterium extorquens

This study shows that reducing peptide deformylase activity in Methylobacterium extorquens increases formaldehyde resistance, with pleiotropic effects and tradeoffs in heat shock resistance.

A deoxynucleoside triphosphate triphosphohydrolase promotes cell cycle progression in Caulobacter crescentus

This study identifies a deoxyguanosine triphosphate triphosphohydrolase (Dgt) that promotes the G1 to S phase transition by regulating dNTP levels in Caulobacter crescentus.
