How Bacteria Outsmart Plants—Then Flee the Scene!

#MicroSky #PlantScience #Pseudomonas

Our new research in Nature Microbiology uncovers the sophisticated teamwork of Pseudomonas syringae, a notorious plant pathogen.

Pseudomonas syringae subpopulations cooperate by coordinating flagellar and type III secretion spatiotemporal dynamics to facilitate plant infection
Nature Microbiology - Single-cell gene expression analysis reveals phenotypic heterogeneity to enable bacterial specialization over the course of plant colonization.

🧬🦠 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.

🔗 doi.org/10.1093/jxb/...
#PlantScience 🧪
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.

#TansleyInsight From bacterial predators to partners: phages in agriculture

Salehimoghaddam et al.

#plantscience
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.

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.
