Mycorrhizal communities in Orchidaceae are likely shaped by plant trophic mode and biogeography but not phylogeny.

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
Mycorrhizal symbioses are prevalent in terrestrial ecosystems and play essential roles in plant nutrition and health. However, the relative importance of plant evolutionary history, physiology, and eco-geographical factors in shaping mycorrhizal fungal community assembly remains poorly understood. Here, we investigate how plant phylogeny, trophic mode, biogeographic distribution and environmental niche collectively influence the diversity and composition of mycorrhizal fungal communities across the Orchidaceae, spanning broad phylogenetic and ecological scales. By using family-wide orchid-fungal associations and global occurrence data, our analyses showed that the variation in fungal diversity and community structure can be partially explained by orchids' trophic mode, biogeographic distribution and environmental niche, but not by their overall phylogenetic relatedness. Among trophic modes, partially mycoheterotrophic orchids exhibited the highest level of fungal diversity (the lowest level of fungal specificity) in association with a broad range of phylogenetically dispersed fungal partners. Between biogeographical regions, a significantly higher level of fungal specificity was found for orchid species distributed in Australia than those in Eurasia and Africa. Furthermore, multivariate analyses showed that a small portion of the variation in fungal community structure was significantly related to broad climate, soil and vegetation variables, indicating the existence of large-scale habitat filtering on orchid mycorrhizal communities. Altogether, our findings indicate that mycorrhizal communities in the orchid family are likely shaped by multiple, intertwined factors related to orchid ecophysiology and biogeography on a global scale.
