Molecular regulation of somatic embryogenesis in potato: an auxin led perspective.
Article in Plant molecular biology, 2008. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 26 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
Potato internodal segments (INS) treated with the auxin 2,4-dichlorophenoxyacetic acid can be induced to develop somatic embryos upon their transfer to an auxin-free medium, while the continuous presence of auxin in the medium suppresses the progression of embryogenically-induced somatic cells to embryos. We have employed these contrasting pathways, in combination with potato microarrays representing circa 10,000 genes, to profile global gene expression patterns during the progression of somatic embryogenesis in potato. The induction phase, characterised by the presence of auxin, was analysed by the direct comparison of RNA isolated from freshly excised (0 days) and embryogenically induced (14 days) INS explants. RNAs from embryo-forming (withdrawal of auxin after 14 days) and embryo-inhibitory (continuous presence of auxin) conditions, isolated over a range of time-points until the emergence of somatic embryos, were compared in a loop design to identify auxin responsive genes putatively involved in the process of somatic embryogenesis. A total of 402 transcripts were found to be showing significant differential expression patterns during somatic embryogenesis 'induction' phase, 524 during 'embryo-transition' phase, while 44 transcripts were common to both phases. Functional classification of these transcripts, using Gene Ontology vocabularies (molecular and biological), revealed that a significant proportion of transcripts were involved in processes which are more relevant to somatic embryogenesis such as apoptosis, development, reproduction, stress and signal transduction. This is the first study profiling global gene expression patterns during true somatic embryogenesis initiated from mature and completely differentiated explants and has enabled the description of stage-specific expression patterns of a large number of genes during potato somatic embryogenesis (PSE). The significance of the key identified genes during critical stages of somatic embryogenesis is discussed.
