In silico comparative analysis of promoters derived from plant pararetroviruses.
Article in Virusdisease, 2017. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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
Promoters are specific sequence of nucleotides present upstream of gene coding region involved in initiation and regulation of transcription. Multiple cis-acting element forms the architecture of promoter to which trans-acting nucleic binding factors bind and regulates its activity. Since 1980 genome of pararetrovirus, are being exploited for developing efficient promoters. Among all of them Cauliflower mosaic virus is the most widely used promoter for gene expression. The basic rational behind the strength of promoter lies in the sequence of cis elements and the spacer nucleotide elements between them, thereby strength of these promoter fragments can be regulated by altering these nucleotide sequences. In the present study sequence of eight putative promoters of plant pararetrovirus are retrieved from National Centre for Biotechnology Information (NCBI) website. These sequence are subjected to various bioinformatics tools comprises of Clustal W, Plant Care, Mathinspector, ModelInspector for establishing the phylogenetic similarity, to identify the quantity and quality of present cis-elements, to find the various common transcription factors binding sites and to determine the presence of module for various specific functions respectively. A range of 28.80-56.0 percentage identification was observed in phylogenetic analysis, with the greatest similarity in Mirabilis mosaic virus and Dahlia mosaic virus. A broad range of cis-elements (51), transcription factor binding site (512) was obtained and 60% observed module are in combination with DOFF motif which shows a function relevance with abiotic stress inducibility. The present study had revealed the functional significance of these elements in gene regulation of pararetrovirus genome and also gives a overall idea for designing novel synthetic promoter.
