Crosstalk between cohesins and axis proteins determines meiotic chromosome architecture in Sordaria macrospora.
Article in PLoS genetics, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
Faithful chromosome segregation during meiosis requires the coordinated action of cohesin complexes and chromosome axis proteins. How these factors interact and communicate along chromosome axes, especially during meiotic prophase I, remains however, only partially understood. We therefore investigated the functional interplay between the cohesin components and regulators (Rad21, Rec8, Wapl, Sororin, Spo76/Pds5) and two meiosis-specific axis proteins Red1 and Hop1. Analysis of multiple combinations of their corresponding null mutants and of their genetic-epistasis interactions in the fungus Sordaria macrospora revealed a hierarchical regulatory network for their recruitment and releasing. This work uncovers an unexpected role of axis proteins Red1 and Hop1, that together with Sororin, provide stage-specific protection of Spo76/Pds5 against Wapl-mediated release. Furthermore, we identify that Spo76/Pds5 is the main target of Wapl and acts as a central guardian of kleisin stability against Slx8/STUbL-dependent proteasomal degradation. Together, our findings show that dynamic crosstalk between axis proteins and cohesins is crucial to preserve axis integrity and to ensure accurate meiotic progression.
