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

Molecular Microbiology, EarlyView.
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.

Dodder seedlings benefit from apoplastic nutrition by inducing SWEET15‐mediated unloading of sucrose from the host's phloem

New Phytologist, EarlyView.
Cuscuta reflexa infection sites. Summary Cuscuta species are holoparasitic plants that penetrate host stems with haustoria, connect to the vasculature and exhaust water, nutrients and carbohydrates. Parasite seedlings possess only limited maternal reserves and the development of a vascular connection takes several days.

Endogenous RALF peptide function is required for powdery mildew host colonization

New Phytologist, EarlyView.
Model of RALF‐FER‐dependent effects on powdery mildew sporulation. Summary The receptor kinase FERONIA (FER) is a susceptibility factor for biotrophic powdery mildew fungal pathogens in Arabidopsis thaliana, but the underlying molecular mechanisms remain largely unknown. FER is required for the perception of endogenous RAPID ALKALINIZATION FACTOR (RALF)

CNGCs in Marchantia paleacea uncouple arbuscular mycorrhizal symbiosis and rhizoid development

New Phytologist, EarlyView.
Rhizoid growth and AM fungal infection are uncoupled. Summary In Marchantia paleacea, MpaDMI1‐dependent nuclear Ca2+ oscillations are essential for arbuscular mycorrhizal (AM) fungal colonisation, indicating that endosymbiosis‐mediated nuclear Ca2+ signalling is a conserved feature of land plant–AM symbiosis.
