Dynamic changes in 3D chromatin structure during male gametogenesis in Arabidopsis thaliana.
Article in Genome biology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
backgroundChromatin higher-order structure plays an important role in genome stability maintenance and gene transcriptional regulation; however, the dynamics of the three-dimensional (3D) chromatin in male gametophytes during the two rounds of mitosis remains elusive.
resultsHere, we use the optimized single-nucleus and low-input Hi-C methods to investigate changes in 3D chromatin structure in four types of male gametophyte nucleus at different stages. The reconstructed genome structures show that microspore nuclei develop towards two different directions. Although the 3D chromatin organization in generative nuclei is similar to that in microspore nuclei, vegetative nuclei lose chromosome territories, display dispersed centromeres, and switched A/B compartments, which are associated with vegetative specific gene expression. Additionally, we find that there is an active transcriptional center in sperm nuclei, emphasizing the transcription in Arabidopsis sperm is not completely inhibited despite the chromosomes being condensed.
conclusionsOur data suggest that the special 3D structures of vegetative and sperm nuclei contribute to cell type-specific expression patterns.
