Tailocin-Mediated Interactions Among Soft Rot Pectobacteriaceae.
Article in Molecular ecology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Bacteria carry phage-derived elements within their genomes, some of which can produce phage-like particles (tailocins) used as weapons to kill kin strains in response to environmental conditions. This study investigates the production and activity of tailocins by plant-pathogenic bacteria: Pectobacterium, Dickeya, and Musicola genera, which compete for niche, providing an attractive model to study the ecological role of tailocins. Microscopy revealed that most analysed strains (88%) produced tailocins. Tailocin-mediated killing interactions were assessed across 351 strain pairs, showing that Dickeya spp. had a higher likelihood of killing neighbours (57.1%) than Pectobacterium spp. (21.6%). Additionally, Dickeya spp. strains exhibited broader phylogenetic killing, targeting both Pectobacterium spp. and Musicola sp., while Pectobacterium spp. tailocins were genus-specific. The mutual (bilateral) killing was observed in 33.9% of interactions, predominantly within Dickeya spp. Although tailocins were morphologically indistinguishable between producers, genomic analyses identified conserved clusters having diverse structural and organisational differences between Pectobacterium spp. and Dickeya spp. tailocins. This suggests different origins of these particles. Induction experiments demonstrated that tailocin production was boosted by hydrogen peroxide, supporting the role of these particles in bacteria-bacteria competition during plant infection when plants produce ROS to protect themselves from pathogens. Tailocins were detectable in infected potato tissue but not in river water, highlighting the particular ecological relevance of tailocins in these studied environments.
