Comparative transcriptomics reveals epigenetic and transcriptional regulatory genes associated with drought stress memory in winter wheat.

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
Wheat is a staple crop vital to global food security, yet its productivity is increasingly threatened by drought. The extent to which contrasting wheat genotypes exhibit stress memory, and how this shapes responses to repeated drought, remains unclear. We investigated intergenerational and transgenerational drought memory in drought-tolerant 'Intro' and drought-sensitive 'Sonalika' using integrated morpho-physiological and transcriptomic analyses. Under repeated stress, seedlings of both genotypes with drought history showed enhanced resilience. Transcriptome profiling identified drought memory genes exhibiting consistent differential expression between initial and repeated stress exposures in seeds and leaves. Gene Ontology analysis revealed enrichment of 'Intro' seed memory genes in transcripts linked to H3K36me3, while leaf memory genes were enriched in pathways related to abscisic acid signaling, osmoprotection, protein synthesis, and antioxidant activity. By contrast, 'Sonalika' showed enrichment of seed transcripts associated with H3K9ac and H3K14ac, and leaf memory genes linked to transcriptional activity, proteostasis, and immune pathways. The functional drought memory exhibited by 'Sonalika', despite the absence of transcripts associated with canonical methylation-based chromatin marks, suggests alternative regulatory strategies. Together, these results indicate that wheat seedlings exhibit genotype-specific drought stress memory involving distinct transcriptional programs and putative epigenetic regulators. While histone modifications were not directly assessed, enrichment of histone-related genes suggests their potential involvement, warranting future chromatin-level validation.
