Transposon based activation tagging in diploid strawberry and monoploid derivatives of potato.
Article in Plant cell reports, 2014. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
key messageDiploid strawberry and potato transformed with a transposon tagging construct exhibited either global (strawberry) or local transposition (potato). An activation tagged, compact-sized strawberry mutant overexpressed the gene adjacent to Ds. As major fruit and vegetable crops, respectively, strawberry and potato are among the first horticultural crops with draft genome sequences. To study gene function, we examined transposon-tagged mutant strategies in model populations for both species, Fragaria vesca and Solanum tuberosum Group Phureja, using the same Activation/Dissociation (Ac/Ds) construct. Early somatic transposition during tissue culture occurred at a frequency of 18.5% in strawberry but not in potato transformants. Green fluorescent protein under a monocot promoter was a more reliable selectable marker in strawberry compared to potato. BASTA (gluphosinate herbicide) resistance served as an effective selectable marker for both species (80 and 85% reliable in strawberry and potato, respectively), although the effective concentration differed (0.5% for strawberry and 0.03% for potato). Transposons preferentially reinserted within genes (exons and introns) in both species. Real-time quantitative PCR revealed enhanced gene expression (670 and 298-fold expression compared to wild type in petiole and leaf tissue, respectively) for an activation tagged strawberry mutant with Ds inserted about 0.6 kb upstream from a gene coding for an epidermis-specific secreted glycoprotein EP1. Our data also suggested that endopolyploid (diploid) cells occurring in leaf explants of monoploid potato were the favored targets of T-DNA integration during transformation. Mutants obtained in these studies provide a useful resource for future genetic studies.
