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

PYL receptor proteins are essential for enhancing plant resilience to extreme environments; however, their functions in woody plants-particularly in response to osmotic stress-remain poorly understood. In this study, we identified and comprehensively characterized 14 PYL genes in Populus trichocarpa. PtrPYL11, a core member, showed up-regulation following both ABA and dehydration treatments, suggesting that it may act as a positive regulator of osmotic stress responses by mediating the expression of ABA-related genes. Specifically, PtrPYL11-overexpressing poplar lines exhibited stronger osmotic stress tolerance than the wild type. Transcriptome analysis revealed that PtrPYL11 may indirectly regulate the expression of core transcription factors such as DOF1 and TCP9, mediating the ABA-signaling pathway in poplar. This study systematically characterizes the molecular features of the PtrPYL gene family and clarifies the role of PtrPYL11 in poplar osmotic stress responses. These findings not only lay a foundation for further exploration of its biological functions but also provide valuable genetic resources for breeding drought-tolerant forest tree varieties through genetic engineering.
