Molecular insights into drought tolerance in wheat through in-silico genome-wide analysis of DREB1 transcription factor and peroxidase interactions.
Article in BMC plant biology, 2025. 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
Wheat (Triticum aestivum) is a staple food crop providing essential nutrition to global population. However, water scarcity and increasing drought stress, because of climate change, threaten its productivity. Oxidative stress increases the production of reactive oxygen species (ROS) due to drought which damages the plant cellular metabolism. Plants counteract this by regulating the transcription of enzymes like catalases, peroxidases, and superoxide dismutase. This research investigated activated biochar's (AB) role on wheat cultivars under deficit irrigation. Activated biochar significantly reduced lipid peroxidation (27-56%) while increasing antioxidant activities (40-60%) under low irrigation as compared to the control (no biochar), suggesting its potential to improve drought resilience. Peroxidase, for presenting significantly higher antioxidant activity, was selected as a key enzyme for molecular docking. Protein-protein interactions between the DREB1 transcription factor and peroxidase, supported by hydrogen bonding, electrostatic interactions, and hydrophobic forces, highlighted the role of biochar mediated peroxidase in oxidative stress response. This interaction highlighted the role of DREB1 in drought resilience, presenting a range of protein sizes, isoelectric points, and stability indices across TaDREB proteins in the wheat genome. Subcellular localization analysis demonstrated that most TaDREB genes, particularly DREB1, are active in the nucleus. At the same time, some are localized to chloroplasts and mitochondria, suggesting diverse roles in stress response and energy metabolism. Phylogenetic analysis grouped DREB genes from wheat (TaDREB), maize (ZmDREB), and Arabidopsis (AtDREB), indicating conserved evolutionary functions across monocot and dicot species. Motif and domain prediction revealed conserved AP2 domains across TaDREB genes, emphasizing their structural and functional conservation, which likely evolved through gene expansion to enhance stress tolerance. These findings are crucial for understanding biochemical attributes of drought responsive transcription factors and their interactive response with antioxidants, which can further help in gene editing technology.
