Normal meiosis in the fungus Sclerotinia sclerotiorum despite the irregular distribution of haploid chromosomes between two nuclei.
Article in Nature communications, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
Sclerotinia sclerotiorum is a phytopathogenic soilborne fungus that damages diverse crops worldwide. It has recently been discovered that this fungus distributes its 16 chromosomes irregularly between two nuclei within each haploid ascospore. Here, we study the meiotic process by tracking phenotypic segregation and recombination events in the progeny of a strain resulting from the fusion of two morphologically distinct mutants. We show that, despite the unusual chromosomal distribution into two nuclei, chromosome segregation and genetic recombination occur normally in S. sclerotiorum, likely due to a tight coordination between the two complementing nuclei during meiosis. Consistently, an atypical ascospore development process deviating from the conventional model was observed. Furthermore, we show that our co-segregation analyses method can be used to identify causal mutations in uncharacterized mutants, uncovering a role for deubiquitination in fungal development and virulence.
