Genome-wide identification and expression analysis of JmjC domain-containing family in Vitis vinifera L.
Article in BMC genomics, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundIn eukaryotes, histone methylation is essential for controlling chromatin structure, gene transcription, and related chromatin processes. Jumonji C (JmjC) domain-containing demethylases (JMJs) regulate histone methylation levels. The JMJ gene family has been discovered in various plants, including Arabidopsis thaliana, Oryza sativa, Malus domestica, and Zea mays.
resultsIn this study, a total of 23 Vitis vinifera VvJMJ gene family members related to histone methylation were identified utilizing genomic and transcript databases. We analyzed the chromosomal location distribution, protein properties, phylogenetic relationships, gene structures, motifs, evolutionary patterns, promoter sequences, and expression profiles of the VvJMJ gene family. The VvJMJ genes were classified into five subfamilies: KDM3, KDM4, KDM5, JMJD6, and JMJC. Co-linearity analysis showed that VvJMJs are highly conserved with AtJMJs and OsJMJs genes. Analysis of the promoter sequences revealed that VvJMJ gene promoter regions are enriched with elements associated with stress response, growth and development, hormone response, and light reactions. Transcriptional profiling and qRT-PCR analysis showed that VvJMJs may play various roles in the multiple biological processes of V. vinifera. For example, VvJMJ2, VvJMJ16, VvJMJ18 may participate in the ripening process of V. vinifera fruits; VvJMJ1, VvJMJ4, VvJMJ6, VvJMJ13, VvJMJ17, VvJMJ20, VvJMJ21, VvJMJ23 may participate in various hormone responses; VvJMJ1, VvJMJ4, VvJMJ10, VvJMJ11 may participate in the stress response of V. vinifera.
conclusionsThis study initially identified the characteristics of V. vinifera JmjC domain-containing genes. The results established a basis for functional analyses of VvJMJ genes in V. vinifera, facilitating the exploration of the mechanisms of underlying the growth, development, and fruit maturation.
