Seed-specific activity of the Arabidopsis β-glucosidase 19 promoter in transgenic Arabidopsis and tobacco.

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
key messageThe promoter of the Arabidopsis thaliana β-glucosidase 19 gene directs GUS expression in a seed-specific manner in transgenic Arabidopsis and tobacco. In the present study, an 898-bp putative promoter of the Arabidopsis β-glucosidase 19 (AtBGLU19) gene was cloned. The bioinformatics analysis of the cis-acting elements indicated that this putative promoter contains many seed-specific elements, such as RY elements. The features of this promoter fragment were evaluated for the capacity to direct the β-glucuronidase (GUS) reporter gene in transgenic Arabidopsis and tobacco. Histochemical and fluorometric GUS analyses of transgenic Arabidopsis plants revealed that the AtBGLU19 promoter directed strong GUS activity in late-maturing seeds and dry seeds, whereas no GUS expression was observed in other organs. The results indicated that the AtBGLU19 promoter was able to direct GUS expression in a seed-specific manner in transgenic Arabidopsis. In tobacco, the intensity of the staining and the level of GUS activity were considerably higher in the seeds than in the other tissues. These results further confirmed that the AtBGLU19 promoter is seed specific and can be used to control transgene expression in a heterologous plant system.
