Mind the Porins: Differential Effects of Porin Knockouts and Overexpression on Glucose and Xylose Uptake and Utilization in Pseudomonas putida

Microbial Biotechnology, Volume 19, Issue 7, July 2026.
Altering the levels of outer membrane (OM) porins has an effect on the dynamics of the utilization and co‐utilization of native (glucose—green hexagon) and non‐native (xylose—brown pentagon) sugars, as well as the accumulation of their oxidation byproducts in Pseudomonas putida cultures.

Differential Effects of Long‐Term Fertilization and Plant Species Richness on Soil Fungi and Protists

Global Change Biology, Volume 32, Issue 7, July 2026.
Fertilization strongly influences plant and soil biodiversity, yet it remains unclear whether fertilization alone drives shifts in soil biota (fungi and protists) or whether associated losses in plant diversity further intensify these effects. Moreover, it is unknown whether fertilization and plant diversity decline act through similar mechanisms or ...

In Salmonella Typhimurium, YiiD Modulates cAMP Levels in Lag Phase During Growth on Succinate

Molecular Microbiology, Volume 126, Issue 1, Page 15-23, July 2026.
The YiiD enzyme, found by others to perform a redundant role in fatty acid biosynthesis, is found to be unexpectedly required for the early increase in cAMP in lag phase during growth on succinate. This intriguing finding suggests a mechanistic link may exist between fatty acid biosynthesis and catabolite repression. ABSTRACT In Salmonella Typhimurium (

Regulation of the Yersinia pseudotuberculosis Type III Secretion System by the CpxAR Two‐Component System

Molecular Microbiology, Volume 126, Issue 1, Page 81-97, July 2026.
Host tissue cues including temperature, oxygen, and iron availability regulate expression of the Yersinia type III secretion system (T3SS) master regulator LcrF. We found that CpxR inhibits LcrF through an indirect, multi‐factorial mechanism and identified the osmolarity‐sensing OmpR/EnvZ system as an additional regulator of LcrF, highlighting ...

Naturally Occurring CodY Variants Alter Ligand Binding, DNA Target Affinity, and Virulence in Clostridioides difficile

Molecular Microbiology, Volume 126, Issue 1, Page 98-110, July 2026.
Single amino acid substitutions in the global regulator CodY can alter nutrient sensing and virulence regulation in Clostridioides difficile. We show that the CodY(Y146N) and CodY(V58A) variants display altered ligand binding and reduced promoter binding, leading to derepression of toxin regulatory pathways and increased virulence in vivo.
