The BRAHMA-associated SWI/SNF chromatin remodeling complex controls Arabidopsis seed quality and physiology.
Article in Plant physiology, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 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
The SWI/SNF (SWItch/Sucrose Non-Fermentable) chromatin remodeling complex is involved in various aspects of plant development and stress responses. Here, we investigated the role of BRM (BRAHMA), a core catalytic subunit of the SWI/SNF complex, in Arabidopsis thaliana seed biology. brm-3 seeds exhibited enlarged size, reduced yield, increased longevity, and enhanced secondary dormancy, but did not show changes in primary dormancy or salt tolerance. Some of these phenotypes depended on the expression of DOG1, a key regulator of seed dormancy, as they were restored in the brm-3 dog1-4 double mutant. Transcriptomic and metabolomic analyses revealed that BRM and DOG1 synergistically modulate the expression of numerous genes. Some of the changes observed in the brm-3 mutant, including increased glutathione levels, depended on a functional DOG1. We demonstrated that the BRM-containing chromatin remodeling complex directly controls secondary dormancy through DOG1 by binding and remodeling its 3' region, where the promoter of the long noncoding RNA asDOG1 is located. Our results suggest that BRM and DOG1 cooperate to control seed physiological properties and that BRM regulates DOG1 expression through asDOG1. This study reveals chromatin remodeling at the DOG1 locus as a molecular mechanism controlling the interplay between seed viability and dormancy.
