Excited to share first preprint from our lab! @giubotti.bsky.social found that antibiotic tolerance in multispecies biofilms follows a surprising spatial pattern: cells survive only at intermediate distances from a partner species. 🦠 Preprint: doi.org/10.64898/202...

We have published a methods paper describing how to identify cell surface receptor complexes by immunoprecipitation and map their phosphorylation sites.
We hope this protocol will be useful to the community. link.springer.com/protocol/10....
Can someone pinpoint if there is a Pseudomonas putida (e.g. KT2442) database where we can find out which lab has certain deletion mutants and/or report strains?
Coming from the B.subtilis field with #SubtiWiki containing all these info, it is difficult to find all available mutants in the papers

Fig. 1.Dynamic regulation and role of plasmodesmata (PD) in viral RNA and siRNA movement. PD regulate the symplasmic transport of molecules between cells. Viruses encode movement proteins (MPs) that are expressed in cells at the viral infection front to facilitate viral movement through PD. Tobamovirus MPs interfere with pattern-triggered immunity (PTI), a defense mechanism activated by plant receptors that recognize viral double-stranded RNA (dsRNA) and cause PD closure by callose deposition. The open state of the PD at the viral infection front, which allows the virus to spread, also allows the movement of signaling molecules, including viral and host-derived small interfering RNAs (siRNAs). As they move ahead of the infection, these siRNAs play a critical role in systemic defense signaling and the regulation of disease outcomes. MIR, miRNA-encoding gene; PTGS, post-transcriptional gene silencing; TGS, transcriptional gene silencing.
🧬🦠 REVIEW 🧬🦠
In this review, Elvira-González et al. describe how virus-induced small RNA synthesis and small RNA movement through plasmodesmata and phloem determine the outcome of viral infection in terms of disease and tolerance.

Conceptual schematic illustrating the multifaceted roles of bacteriophages (phages) in sustainable agriculture. The figure shows four panels depicting phage-driven processes in soil ecosystems: suppression of bacterial plant pathogens through virulent phage lysis; enhancement of plant growth-promoting bacteria via temperate phage integration and competitive advantages; detection of soil pathogens using phage-based biosensors that generate measurable signals; and phage-mediated soil bioremediation through auxiliary metabolic genes that enable bacterial degradation of environmental pollutants. Together, the panels summarize how phages influence soil microbiomes and plant health.

Developmental and abiotic stress assays in Columbia-0 (Col-0) and mutants (abi1-1 and defenseless).
Decoding plant defense signaling using the defenseless mutant
Baral and Brosché
nph.onlinelibrary.wiley.com/doi/10.1111/...
An Arabidopsis leaf-infection assay with Alternaria alternata showing lesions on Col-0, defenseless (abi1-1 coi1 eds1 ein2 rbohD sid2) and cyp79b2b3 plants. The lesions are worst on cyb79b2b3, intermediate on the defenseless plant, and least on Col. Similarly, plants infected with Pseudomonas syringae show strongest susceptibility in an eds1 sid2 background, medium susceptibility in defenseless, and least in Col.
Interesting that a 𝘥𝘦𝘧𝘦𝘯𝘴𝘦𝘭𝘦𝘴𝘴 mutant (𝘢𝘣𝘪𝟣-𝟣 𝘤𝘰𝘪𝟣 𝘦𝘥𝘴𝟣 𝘦𝘪𝘯𝟤 𝘳𝘣𝘰𝘩𝘋 𝘴𝘪𝘥𝟤) is less sensitive to fungal infection than a 𝘤𝘺𝘣𝟩𝟫𝘣𝟤/𝘣𝟤 mutant (Similarly, 𝘦𝘥𝘴𝟣 𝘴𝘪𝘥𝟤 is more susceptible to bacterial infection than the 𝘥𝘦𝘧𝘦𝘯𝘴𝘦𝘭𝘦𝘴𝘴).
