Mother trees of common ash (Fraxinus excelsior) disperse different sets of mycobiome through their seed wings.
Article in BMC research notes, 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
objectiveThe endophytic mycobiome is present in all studied plant compartments, including fruits and seeds. Here, we studied the mycobiome of seed wings as they are transferred with seeds in common ash and tested whether the mycobiome differs among trees. To achieve this, we used ITS1-based amplicon sequencing and two genotypes of F. excelsior as a model to compare the mycobiome of mother trees and their wings.
resultsWe compared the mycobiome of 57 seed wings to the seed stalks (57) collected from two genotypes of F. excelsior using three ramets of each genotype. Alpha diversity indices (ACE, Fisher and Observed OTUs) suggested a higher richness of the mycobiome associated with the seed wing than the seed stalk within each genotype. However, there were neither significant differences in Shannon diversity between the mycobiomes from the two tissue types nor the two genotypes. PERMANOVA revealed significant differences in the mycobiome composition between tissue types (P < 0.001). It also showed a significant difference between seed wings (P = 0.04), but not between seed stalks of the two genotypes. Our results suggest that Fraxinus excelsior mother trees disperse different sets of mycobiomes with their seed wings, which may be important for germination and seedling establishment-especially in the light of ash dieback.
