Arabidopsis HRE1α, a splicing variant of AtERF73/HRE1, functions as a nuclear transcription activator in hypoxia response and root development.
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 10 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 messageHRE1α shows transcriptional activation activity in its C-terminal region via GCC box but not DRE/CRT and plays an important role in root development via root meristem cell division regulation. AtERF73/HRE1 protein, a member of the Arabidopsis AP2/ERF family, contains a conserved AP2/ERF DNA-binding domain. Here, we studied the molecular function of HRE1α, a splicing variant of AtERF73/HRE1, as well as its role in root development. HRE1α-overexpressing transgenic plants (OXs) showed tolerance to submergence. HRE1α showed transcriptional activation activity via GCC box but not DRE/CRT. The 121-211 aa region of HRE1α was responsible for the transcriptional activation activity, and the region was conserved among homologs of other species but was not found in other Arabidopsis proteins. HRE1α OXs showed increased primary root length due to elevated root cell division. Our results suggest that HRE1α functions as a transcription activator in the nucleus, and plays an important role in root development through regulation of root meristem cell division.
