Molecular analysis of hormone-regulated petal regeneration in Petunia.
Article in Plant cell reports, 2008. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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 petal is an important floral organ of higher plants. To study the mechanism of petal development, the in vitro regeneration system of petals was established in Petunia. High-frequency induction of petals occurred directly from explants on the media containing the combination of N6-benzyladenine (6-BA) and indole-3-acetic acid (IAA). Expression analysis of genes involved in flower development indicated that these genes were classified into three types. ABERRANT LEAF AND FLOWER (ALF) gene was induced during petal regeneration. Whereas, B-class and E-class genes, and genes involved in cell division were constitutively upregulated. In contrast, C-class and D-class genes were not expressed in explants and regenerated tissues. Further, in situ hybridization analysis showed that both ALF and GREEN PETAL (GP) expression were spatially regulated. The results suggest that differential regulation of gene expression occurs in the presence of hormones during petal regeneration, and hormone-regulated gene expression might be required for petal regeneration. This study provides the preliminary information to understand the mechanism of petal regeneration.
