Regulatory role of epigenetics in rice immunity against bacterial and fungal pathogens.
Review in Crop health, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Rice (Oryza sativa), a major crop, faces significant threats from various pathogens, which affect global food security. Recent research in plant biology highlights the crucial role of epigenetic mechanisms in regulating rice immunity. Epigenetics involves heritable changes in gene expression without alterations to the DNA sequence, mediated by DNA methylation, histone modifications, and non-coding RNAs. This review critically evaluates the role of epigenetics in rice immunity, focusing on key epigenetic modifications and their impact on disease resistance, including WRKY transcription factors and epigenetic regulatory factors, such as RdDM (RNA-directed DNA methylation). These epigenetic regulators enable rice plants to dynamically withstand pathogen attacks by modulating the expression of defense-related genes. This review evaluates the epigenetic responses of rice to major pathogens, including Magnaporthe oryzae (M. oryzae) and Xanthomonas oryzae (Xoo). We move beyond simple descriptions of epigenetic marks to analyze the functional integration of these pathways and their trade-offs with plant growth. Finally, we discuss the potential of "epigenetic breeding" and CRISPR-based epi-editing as a sustainable frontier for developing broad-spectrum resistance in rice. Future research should focus on identifying specific epigenetic markers associated with resistance traits and integrating epigenetic approaches with traditional breeding and biotechnological methods to achieve sustainable rice production and ensure food security in the face of evolving pathogen threats.
