Differential expression of U5snRNA gene variants in maize (Zea mays) protoplasts.
Article in Plant molecular biology, 1993. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
The small nuclear ribonucleoprotein particles U1, U2, U4/U6 and U5 participate in the removal of introns from pre-messenger RNAs in the nucleus. Three genes encoding U5snRNAs, the RNA moiety of U5snRNPs, have been isolated from maize. As in other plant UsnRNA gene families the three maize U5snRNA genes exhibit sequence variation. Two of the gene variants (MzU5.1 and MzU5.2) are clearly expressed after transfection into maize leaf protoplasts while the third gene variant (MzU5.3) is expressed at very low levels. These different levels of expression cannot be directly correlated with sequence changes in the highly conserved Upstream Sequence Element (USE) required for expression of Arabidopsis UsnRNA genes nor with differential stability of the U5snRNA transcripts. Further sequence elements may therefore have a role in regulating maize UsnRNA gene expression.
