1 · What the graph read from it

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.

2 · The registry

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

key messagePepper CcSnRK2.5 confers drought adaptation, off ering a key genetic resource for crop improvement. Drought stress remains a paramount constraint on agricultural productivity, threatening global food security by impairing plant growth and inducing yield instability. As central mediators of plant stress adaptation, sucrose non-fermenting 1-related protein kinase 2 (SnRK2) family members orchestrate complex abiotic stress signaling networks. In this study, we systematically identified SnRK2 orthologs in pepper (Capsicum chinense), which were phylogenetically categorized into three distinct subgroups. Promoter analysis revealed a significant enrichment of ABA-responsive elements (ABREs) and drought-associated cis-regulatory motifs. Spatiotemporal expression profiling uncovered divergent transcript abundance patterns in leaves and roots under progressive drought stress, demonstrating organ-specific regulation of SnRK2-mediated stress perception. Functional validation via virus-induced gene silencing (VIGS) of CcSnRK2.5 in pepper significantly augmented drought susceptibility, evidenced by increased oxidative damage and water loss. Conversely, heterologous overexpression of CcSnRK2.5 in Arabidopsis thaliana enhanced drought tolerance by modulating the expression of key ABA-responsive marker genes. Collectively, these findings elucidate the regulatory role of SnRK2 genes in drought stress adaptation and provide promising genetic targets for the molecular breeding of drought-resilient pepper cultivars.
