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

Kentucky bluegrass (Poa pratensis L.) is a widely used cool-season turfgrass in the world. However, the underlying responses of drought-induced morpho-physiology and gene regulation remain to be elucidated for this grass species. This study examines the phenotypic, physiological, and transcriptional differences between the drought-tolerant cultivar ‘Maoershan’ and the drought-sensitive cultivar ‘Brilliant’ under varying levels of drought stress, aiming to identify phenotypic traits and key pathways associated with different drought-resistant varieties. Under different levels of drought stress, ‘Maoershan’ exhibited stronger drought adaptability, characterized by a slower decline in turf quality, morphological indicators and photosynthetic efficiency, alongside a greater increase in soluble sugar content and antioxidant enzyme activities. In contrast, ‘Brilliant’ showed more pronounced membrane damage and hormone imbalance. Transcriptome analysis identified 75,166 differentially expressed genes (DEGs). Under the same drought condition, the number of DEGs in ‘Brilliant’ was higher, and the changes in gene expression observed in the ‘Brilliant’ were more significant than those in the ‘Maoershan’. Weighted gene co-expression network analysis (WGCNA) revealed a key gene module highly correlated with drought tolerance. This module was significantly enriched in the plant hormone signal transduction pathway, particularly the abscisic acid (ABA) signaling pathway. Further analysis revealed that changes in ABA signaling pathway gene expression in ‘Maoershan’ were more stable than those in ‘Brilliant’ as drought progressed, such as PP2C37 (Cluster-4199.118277), ABI5 (Cluster-4199.122824), and SAPK4 (Cluster-4199.57749). These findings indicated that the differences in gene expression of the ABA signal transduction pathway conferred better drought tolerance in ‘Maoershan’ than in ‘Brilliant’. This study could help elucidate the mechanisms underlying drought tolerance in Kentucky bluegrass, thereby facilitating genetic improvements aimed at reducing water input in turfgrass management.
