Isolation and functional characterization of a novel rice constitutive promoter.
Article in Plant cell reports, 2014. 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
key messageA novel rice constitutive promoter (P OsCon1 ) was isolated. The molecular mechanism of the promoter activity was investigated. P OsCon1 could be used as an alternative constitutive promoter for crop transgenic engineering. Monocot constitutive promoter is an important resource for crop transgenic engineering. In this report, we isolated a novel promoter, Oscon1 promoter (P OsCon1 ), from the 5' upstream region of a constitutively expressed rice gene OsDHAR1. In P OsCon1 ::GUS transgenic rice, we showed that P OsCon1 had a broad expression spectrum in all tested tissues. The expression of the promoter was further analyzed in comparison with the previously characterized strong constitutive promoters. P OsCon1 exhibited comparable activity to OsCc1, OsAct1 or ZmUbi promoters in most tissues, and more active than 35S promoter in roots, seeds, and calli. Further quantitative assays indicated that P OsCon1 activity was not affected by developmental stages or by environmental factors. Further, 5'-deletions analysis indicated that the distinct regions might contribute to the strong expression of P OsCon1 in different tissues. Overall, our results suggest that P OsCon1 is a novel constitutive promoter, which could potentially use in transgenic crop development.
