Bamboo mosaic potexvirus satellite RNA (satBaMV RNA)-encoded P20 protein preferentially binds to satBaMV RNA.
Article in Journal of virology, 1999. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 13 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 satellite RNA of 836 nucleotides [excluding the poly(A) tail] depends on the bamboo mosaic potexvirus (BaMV) for its replication and encapsidation. The BaMV satellite RNA (satBaMV) contains a single open reading frame encoding a 20-kDa nonstructural protein (P20). The P20 protein with eight histidine residues at the C terminus was overexpressed in Escherichia coli. Experiments of gel retardation, UV cross-linking, and Northwestern hybridization demonstrated that purified P20 was a nucleic-acid-binding protein. The binding of P20 to nucleic acids was strong and highly cooperative. P20 preferred binding to satBaMV- or BaMV-related sequences rather than to nonrelated sequences. By deletion analysis, the P20 binding sites were mainly located at the 5' and 3' untranslated regions of satBaMV RNA, and the RNA-protein interactions could compete with the poly(G) and, less efficiently, with the poly(U) homopolymers. The N-terminal arginine-rich motif of P20 was the RNA binding domain, as shown by in-frame deletion analysis. This is the first report that a plant virus satellite RNA-encoded nonstructural protein preferentially binds with nucleic acids.
