Do Streptomyces sp. Help Mycorrhization in Raspberry?
Article in Current microbiology, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Actinobacteria may help the mycorrhizal symbiosis by producing various bioactive metabolites. Mycorrhizae, in turn, are very important since they increase the absorption of nutrients, promoting the growth of their host plant and making inoculation with arbuscular mycorrhizae fungi (AM) a common practice applied in agriculture and forestry. The cultivation of Rubus idaeus (raspberry) is widespread in Patagonia, Argentina; however, the potential benefits of using actinobacteria-mycorrhizal inoculums to enhance crop growth and yield remain unexplored. The objective of this work was to study the interaction between actinobacteria (Streptomyces, Actinomycetota) and AM in raspberry plants. We performed an experiment applying 4 treatments to raspberry plants growing in two substrates, sterile soil and natural (non-sterile) soil. The treatments consisted in a control (without inoculation) and three inoculations treatments (AM, Streptomyces SH9 strain, and AM + Streptomyces). After 3 months of inoculation, mycorrhization parameters (%) and plant growth were recorded. When comparing both substrates, the mycorrhization parameters were higher in natural soil than in sterile soil. The co-inoculation with AM + Streptomyces SH9 showed the highest mycorrhization. Both factors (treatment x substrate) interacted showing that in sterile soil the treatments with the highest effect on mycorrhization parameters were AM and the co-inoculation, while in natural soil all inoculations improved mycorrhization parameters, being highest with the co-inoculation. These results show that Streptomyces SH9 strain helps the mycorrhizal symbiosis in raspberry, being the first report about the effect of a native rhizospheric actinobacterium on an economically important species, promising potential for environmentally friendly improvements in raspberry crops within the temperate Southern Patagonian region.
