Microbiome eco-evolution of cultivated and wild rice species across the genus Oryza and its importance in supporting rice growth.

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
backgroundCrop wild relatives and their microbiomes are essential for sustainable crop production. However, the co-evolution of wild rice species and their microbiomes remains poorly understood. Herein, we investigated microbiome assembly across 17 wild rice and one cultivated rice species under controlled conditions spanning ~15 million years of evolution.
resultsOur data reveal distinct eco-evolutionary patterns for bacteria and fungi. Host divergence time was the predominant driver of root microbiota structure, outweighing polyploidy and life cycle, and exerted a stronger effect on bacteria than fungi. Bacterial community exhibited a significant phylosymbiosis with its host, but fungi did not. Over evolutionary time, bacterial diversity decreased while phylogenetic clustering increased. Deterministic and stochastic processes co-drove bacteria assembly, whereas stochastic processes strongly drove fungi assembly. Potentially functional taxa, including nitrogen-fixing and methane-cycle bacteria, were differentially enriched across evolutionary time and polyploidization events. Notably, co-speciating bacteria better predicted grain weight than fungi, with core species making a major contribution. Using a synthetic community (SynCom) derived from the wild rice core microbiome and four nitrogen-fixing strains enriched in early- and medium-diverging Oryza species, we demonstrated that the SynCom strongly promoted rice growth, with the removal of key members markedly reducing its impact.
conclusionsThese results reveal co-phylogenetic patterns between Oryza and root-associated bacteria, highlighting the closer functional linkage between rice traits and bacteria than fungi, likely due to their co-evolution. Our findings provide new insights into crop-microbiome symbiosis from an eco-evolutionary perspective and underscore the importance of co-speciating microbiomes from wild relatives in supporting crop growth.
