Gene expression in opening and senescing petals of morning glory (Ipomoea nil) flowers.
Article in Plant cell reports, 2007. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 16 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
We isolated several senescence-associated genes (SAGs) from the petals of morning glory (Ipomoea nil) flowers, with the aim of furthering our understanding of programmed cell death. Samples were taken from the closed bud stage to advanced visible senescence. Actinomycin D, an inhibitor of transcription, if given prior to 4 h after opening, suppressed the onset of visible senescence, which occurred at about 9 h after flower opening. The isolated genes all showed upregulation. Two cell-wall related genes were upregulated early, one encoding an extensin and one a caffeoyl-CoA-3-O-methyltransferase, involved in lignin production. A pectinacetylesterase was upregulated after flower opening and might be involved in cell-wall degradation. Some identified genes showed high homology with published SAGs possibly involved in remobilisation processes: an alcohol dehydrogenase and three cysteine proteases. One transcript encoded a leucine-rich repeat receptor protein kinase, putatively involved in signal transduction. Another transcript encoded a 14-3-3 protein, also a protein kinase. Two genes have apparently not been associated previously with senescence: the first encoded a putative SEC14, which is required for Golgi vesicle transport, the second was a putative ataxin-2, which has been related to RNA metabolism. Induction of the latter has been shown to result in cell death in yeast, due to defects in actin filament formation. The possible roles of these genes in programmed cell death are discussed.
