Arabidopsis inositol polyphosphate kinase activities regulate COP9 deneddylation functions in phosphate homeostasis

Journal of Integrative Plant Biology, EarlyView.
Plant phosphate (Pi) homeostasis relies on coordinated activities of the inositol polyphosphate kinases IPK1 and ITPK1, which balance localized InsP7 biosynthesis to control COP9 signalosome (CSN)‐dependent deneddylation of cullin 1 (CUL1). Perturbation of this equilibrium affects the stability of SPX4, a key negative regulator of phosphate starvation ...

Phloridzin Mitigates Aging‐Associated Periodontitis by Restraining Inflammatory Cell Death

Journal of Periodontal Research, EarlyView.
Phloridzin attenuated oxidative stressinduced senescence, inflammatory responses, and osteogenic dysfunction in HPDLCs. In an aging‐associated experimental periodontitis model, phloridzin alleviated alveolar bone loss, suggesting its potential to maintain periodontal tissue integrity under aging‐related inflammatory conditions.

A Single‐Nucleotide Substitution Generates a de Novo Promoter That Activates a Latent Metabolic Bypass in Escherichia coli

Molecular Microbiology, EarlyView.
A chromosomal mutation allows bypass of deletion of the Escherichia coli fabH gene. The bypass results from creation of a new promoter that drives increased madA transcription, resulting in increased synthesis of acetyl‐acyl carrier protein by decarboxylation of malonyl‐acyl carrier protein.

A Nutrient‐Responsive LuxR Regulator Orchestrates Effector Gene Expression Across the Legionella Genus

Molecular Microbiology, EarlyView.
LexR1 is a LuxR‐type regulator that links nutrient sensing to effector gene expression in Legionella. Activated by a casamino acid‐derived ligand, LexR1 directly controls multiple effector genes using a conserved regulatory element present in numerous putative effectors across different Legionella species.

The Role of torS and torT Transcription in Driving a Bet‐Hedging Strategy for Trimethylamine N‐Oxide Reductase Expression in Escherichia coli

Molecular Microbiology, EarlyView.
Low basal activity of divergent promoters driving transcription of the trimethylamine N‐oxide (TMAO) sensor TorT and kinase TorS is integral to an O2‐regulated bet‐hedging strategy for continued E. coli growth upon the onset of anaerobiosis. This, along with repression by IscR, promotes noise in the TorS to TorT ratio, which is critical for adaptation ...
