The poplar VQ1 gene confers salt tolerance and pathogen resistance in transgenic Arabidopsis plants via changes in hormonal signaling.

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
The VQ protein family is plant-specific, and is involved in growth, development, and biotic and abiotic stress responses. In this study, we found that the gene expression of poplar VQ1(Potri.001G029700) from Populus trichocarpa varied remarkably under salt stress and hormones associated with disease. A subcellular localization experiment showed that VQ1 was localized in the nucleus and cytomembrane in tobacco. The overexpression of VQ1 in Arabidopsis thaliana enhanced its resistance to salt stress and disease, and was also responsive to it through abscisic acid. Compared with wild-type, transgenic Arabidopsis lines had significantly increased levels of abscisic acid and salicylic acid. The expression of some stress-related genes, such as MPK6, NPR1, and PDF1.2, was significantly up-regulated by salt in transgenic plants, while WRKY70, ABI1, KUP6, and NCED2 were significantly down-regulated by Pseudomonas syringae pv. tomato DC3000 in transgenic plants. Together, these results demonstrate that VQ1 modulates hormonal signaling to confer multiple biotic and abiotic stress responses in transgenic Arabidopsis plants.
