Mycorrhizal type modifies the position of exudation carbon within the root economics space.
Article in Nature communications, 2026. 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
The trait‑based root economics space provides a fundamental framework for understanding plant belowground adaptation to environmental change, yet it typically omits root exudation that sustains plant resource acquisition and health. Results from a ~3500 km north‑south forest transect demonstrate that arbuscular mycorrhizal (AM) trees have higher root exudation rates than ectomycorrhizal (ECM) trees, with stronger increases under warmer and wetter climates. Root exudation rate is positively related to specific root length and negatively related to root diameter for both mycorrhizal types, but is related to tissue density and nitrogen content only in AM trees. These findings suggest that root exudation may represent an alternative collaboration strategy, facilitating organic nutrient acquisition more strongly for AM species and functioning as a relatively redundant nutrient acquisition mechanism for ECM species. Moreover, mycorrhizal type modulates how exudation rates relate to the "fast-slow" strategy. Overall, our findings refine the conceptual framework of the root economics space and enhance understanding of fine‑root strategies.
