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

Orchardgrass is a vital forage crop worldwide, yet its growth and yield are highly susceptible to environmental stress. Small Heat Shock Proteins (sHSPs) family is a wide protein family crucial for enhancing plant stress tolerance. Nevertheless, a comprehensive understanding of the sHSP family in orchardgrass is lacking, particularly concerning its response to abiotic challenges. In the present study, we identified 47 sHSP family members in orchardgrass and provided a comprehensive analysis of their characteristics. Syntenic analysis revealed that the expansion of DgsHSP is primarily driven by tandem duplication events. Multiple abiotic challenges were shown to stimulate certain DgsHSP genes, suggesting they play a key regulatory role in how orchardgrass responds to these stresses. Heterologous expression in yeast demonstrated that DgsHSP30 and DgsHSP31 improve tolerance to drought and salt stress. Additionally, physiological indicators and phenotypes under stress in Arabidopsis mutants also support this viewpoint. These findings lay the groundwork for understanding the functional role of the DgsHSP family in orchardgrass under environmental stress, offering potential applications for enhancing forages and crops through breeding programs.
