Isolation of a maize ZmCI-1B promoter and characterization of its activity in transgenic maize and tobacco.
Article in Plant cell reports, 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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 2-kb ZmCI - 1B promoter is active in the root and embryo and induced by wounding in maize and the 220-bp 5'-deleted segment maybe the minimal promoter. The subtilisin-chymotrypsin inhibitor gene, CI-1B of Zea mays (ZmCI-1B), has been suggested to induce the maize defense system to resist insect attack. Real-time RT-PCR showed that ZmCI-1B gene exhibited especially high expression in roots and embryos. The 2-kb full-length promoter of ZmCI-1B gene was isolated from the maize genome and used to drive expression of a beta-glucuronidase (GUS) reporter gene for transient expression and stable expression analysis in maize. The results of GUS histochemical staining in transgenic maize plants revealed that the ZmCI-1B promoter induced GUS expression preferentially in roots and embryos and in response to wounding. A series of 5'-deleted segments of the ZmCI-1B promoter were cloned individually to drive GUS expression for further analysis. Deletion analysis combined with the histochemical staining of transgenic tobacco plants revealed 220-bp segment could drive GUS in a tissue-specific and wounding-induced expression in tobacco; thus, it maybe the minimally active promoter of ZmCI-1B gene. Furthermore, it revealed that the ZmCI-1B promoter contained tissue-specific and wounding-induced elements.
