Functional characterization of protein SUMOylation in the miRNA transcription regulation during heat stress in Arabidopsis.
Article in The plant genome, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
MicroRNAs (miRNAs) play an essential role as non-coding-RNA-type epigenetic regulators in response to high-temperature stress in plants. There are crucial roles for global transcriptional regulation under SUMO (small ubiquitin-related MOdifier) stress response (SSR). However, the molecular mechanisms underlying its downstream regulation remain unclear. In this study, SUMO-specific chromatin immunoprecipitation sequencing analysis detected specific binding in the promoter region of miRNAs under high-temperature stress. A correlation analysis between this binding and miRNA profiling revealed that the location of SUMO on the chromosome was correlated with the expression pattern of miRNAs, particularly miR398a and miR824a. In contrast, knockout mutants of the SSR-dependent SUMO E3 ligase SAP AND MIZ 1 in Arabidopsis exhibited opposing trends in target gene expression for the SUMO-related miRNAs compared to the wild type. Multi-omics correlation analyses identified 34 SUMO-candidate proteins that might be involved in the regulation of miRNA response to high-temperature stress. Therefore, we propose a potential model whereby high-temperature exposure induces nuclear entry of SUMO molecules, modifying specific transcription factors that bind to miRNA gene promoters and potentially regulate miRNA expression.
