Regulation of the rose Rh-PIP2;1 promoter by hormones and abiotic stresses in Arabidopsis.
Article in Plant cell reports, 2009. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 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
Our previous work has indicated that an ethylene-responsive aquaporin gene, Rh-PIP2;1, played an important role in the epidermal cell expansion of rose petals. In this work, we isolated an 896 bp promoter sequence of the Rh-PIP2;1 and found that the promoter was rare in plants, occurring with an Inr motif, but without a TATA box. In transgenic Arabidopsis harboring the Rh-PIP2;1 promoter::GUS construct, the activity of Rh-PIP2;1 promoter was found to be developmental-dependent in almost all of the tested organs, and was particularly active in organs that were rapidly expanding, and in tissues with high water flux capacity. Moreover, the promoter activity was inhibited by ACC, ABA, NaCl, and cold in the roots of 3 or 6-day-old plants, and was increased by GA(3) and mannitol in the rosettes of 9 or 12-day-old plants. Deleting the fragment from -886 to -828 resulted in nearly complete disappearance of the promoter activity in roots, and a substantial decrease in the leaves, hypocotyls and floral organs. Taken together, our results indicated that the Rh-PIP2;1 promoter responded to hormones and abiotic stresses in a developmental- and spatial-dependent manner, and the -886 to -828 region was crucial for the activity of the Rh-PIP2;1 promoter.
