INCREASED DNA METHYLATION 3 forms a potential chromatin remodelling complex with HAIRPLUS to regulate DNA methylation and trichome development in tomato.

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
DNA methylation, a dynamic epigenetic mark influencing gene expression, is regulated by DNA demethylases that remove methylated cytosines at genomic regions marked by the INCREASED DNA METHYLATION (IDM) complex. In Arabidopsis, IDM3, a small α-crystalline domain-containing protein, stabilises the IDM complex. To investigate its role in tomato, we generated slidm3 mutants using genome editing. These mutants displayed a 'hairy' phenotype with increased glandular trichomes, resembling the hairplus (hap) mutant. Affinity purification of SlIDM3-GFP associated proteins identified several chromatin remodelling factors, including HAP. Genome-wide DNA methylation analysis revealed sequence context dependent alterations in the slidm3-1 plants, similar to the hap mutant. CHH methylation was predominantly increased, while CG methylation, particularly in intergenic regions, was decreased in both mutants. This imbalanced methylation suggests the presence of a 'methylstat' mechanism attempting to restore methylation levels at abnormally demethylated sites in the mutants. Comparative functional analysis of differentially methylated regions in the slidm3-1 and hap mutants identified potential methylation-regulated genes that could be linked to the hairy phenotype. Our findings indicate that SlIDM3 may form a chromatin remodelling complex with HAP, epigenetically regulating trichome development.
