Powerful effect of an atypical bifactorial endosperm box from wheat HMWG-Dx5 promoter in maize endosperm.
Article in Plant molecular biology, 2002. 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 proximal region of the high-molecular-weight glutenin promoter of the Dx5 gene (PrHMWG-Dx5) carries an atypical bifactorial endosperm box containing two cis-acting elements, namely a G-box like motif followed by a prolamin-box motif (Pb1). Transient expression assays in maize endosperm indicate that a promoter fragment containing at least the G-box like element is necessary and sufficient for maximal expression of the HMWG-Dx5 promoter. In transformed maize, we have shown that a 89 bp sequence bearing the bifactorial endosperm box behaves like a functional cis-acting unit. Its repetition in tandem confers a strong specific additive effect specifically in endosperm tissue. In contrast, the fusion of the activation sequences 1 (as-1) and 2 (as-2) of the cauliflower mosaic virus (CaMV) 35S promoter with HMWG-Dx5 derived promoter sequences deregulates its activity in transformed maize. By gel mobility shift assays we have demonstrated that the G-box like motif may alternatively bind two protein groups which have the same DNA-binding affinities as the transcription factors of either the Opaque2 (O2) family and/or the ASF-1 family.
