Subcellular localization of MURA and MURB proteins encoded by the maize MuDR transposon.
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 12 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
MuDR controls transposition of the Mu transposable element family in Zea mays L. It produces two major transcripts: mudrA and mudrB, mudrA encodes the MURA transposase, but no specific function has been ascribed to mudrB, which lacks strong homology to known genes. Using transient expression assays in onion epidermal cells, we defined three monopartite nuclear localization signals (NLSs) of MURA; each was functionally sufficient for nuclear targeting of MURA:GUS fusion proteins. Interestingly, one NLS (NLS-A3) is produced by the splicing of the third intron. In contrast, there were no clear NLS in MURB, and the major form of MURB aggregated in the cytoplasm. Self-interaction of MURA and of MURB was also shown in a yeast two-hybrid assay. To test whether interactions of MURA and MURB can occur at the level of protein translocation into the nucleus, a cytoplasmically localized MURB:GFP was co-expressed with MURA or with the GUS fusion proteins. Co-expression did not change the localization pattern of either MURA or MURB; MURA and MURB do not detectably interact in a yeast two-hybrid assay. These results suggest that MURA and MURB do not mutually affect their localization, at least in the forms examined here.
