Molecular dissection of the interaction between the transcriptional activator ZmMRP-1 and the promoter of BETL-1.
Article in Plant molecular biology, 2006. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 16 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
The interaction between the transfer cell specific transcriptional activator ZmMRP-1 and the promoter of the transfer cell specific gene BETL-1 constitutes an exceptionally robust system. Reporter constructs containing the BETL-1 promoter are virtually silent in a variety of cell types, from maize leaves to yeast. The introduction of ZmMRP-1 in co-transformation assays leads to the transactivation of the reporter construct by up to two orders of magnitude. In this work we have investigated the molecular basis of this interaction. We found that the BETL-1 promoter includes four potential targets for ZmMRP-1 binding, consisting of a 12 bp motif containing two repeats. Co-transformation assays and electrophoretic mobility shift experiments identified the sequence TATCTCTATCTC as the preferred one for the interaction with the transcription factor. Identification of similar sequences in other transfer cell specific promoters lead us to propose as a transfer cell box a sequence related to those identified in the BETL-1 promoter, positioned 50-100 bp upstream the TATA box.
