Genome-wide identification and alkaline stress response analysis of the class III peroxidase (PRX) gene family in Castanea mollissima.
Article in BMC plant biology, 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
backgroundClass III peroxidases (PRXs) are plant-specific proteins crucial for growth, development, and stress responses. Castanea mollissima is an important woody crop; however, soil alkalization, a common environmental stressor, limits the sustainable development of its agricultural ecology. The evolution of the PRX gene family and its regulatory mechanisms under alkaline stress in this species remain unclear.
resultsIn the Castanea mollissima genome, 98 CmPRX genes were identified, distributed unevenly across 12 chromosomes and classified into eight subfamilies. Tandem duplication was the primary driver of the expansion of this gene family. Under alkaline stress, key physiological indicators (SOD and CAT activities, MDA content) in leaves changed significantly, reflecting the plant's physiological response and adaptive potential under such conditions. Integration of transcriptomic and physiological data revealed highly differentiated expression patterns among CmPRX members. The reliability of the RNA-seq data was validated by RT-qPCR analysis. Weighted Gene Co-expression Network Analysis (WGCNA) identified specific modules significantly correlated with antioxidant enzyme activities, suggesting a pivotal role for this gene family in regulating oxidative balance.
conclusionsThis study systematically clarifies the evolutionary characteristics of the CmPRX gene family and its expression regulatory network under alkaline stress. The findings provide a theoretical basis and candidate gene resources for improving alkaline tolerance in C. mollissima through genetic breeding, and offer important insights for selecting stress-tolerant varieties in regions affected by soil alkalization.
