Sequence-specific interactions of wound-inducible nuclear factors with mannopine synthase 2' promoter wound-responsive elements.
Article in Plant molecular biology, 1996. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 9 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
A 318 bp mannopine synthase 2' (mas2') promoter element from the T-DNA of Agrobacterium tumefacians can direct wound-inducible and root-preferential expression of a linked uidA gene in transgenic tobacco plants. Wound inducibility is further enhanced by sucrose in the medium. Promoter deletion analysis indicated that the sucrose enhancement is conferred by a region extending from -318 to -213. DNase I footprinting indicated that an A/T-rich DNA sequence in this region is protected by tobacco nuclear factors. Regions extending from -103 to +66 and from -213 to -138 directed wound-inducibile expression of a linked uidA gene when placed downstream of a CaMV 35S enhancer or upstream of a truncated (-209) CaMV 35S promoter, respectively. DNase I footprinting analyses indicated that proteins from wounded tobacco leaves specifically bound to three contiguous motifs downstream of the mas2' TATA box. In addition to a common retarded band formed by the upstream wound-responsive element complexed with proteins from either wounded or unwounded tobacco leaves, two unique retarded bands were observed when this element was incubated with protein from wounded leaves. Methylation interference analysis additionally identified an unique motif composed of promoter elements and nuclear factors derived specifically from wounded tobacco leaves. We propose a model to describe the involvement of nuclear factors with mas2' promoter elements in wound-inducible gene expression.
