Gene expression associated with apogamy commitment in Ceratopteris richardii.
Article in Sexual plant reproduction, 2012. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 9 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
Apogamy is a phenomenon in which a sporophyte develops asexually, directly from a cell or cells of a gametophyte. It is a phenomenon described mainly in lower plants, but shares certain aspects with apomixis in angiosperms. The genes involved in apogamy commitment in ferns are unknown. We hypothesize that the mechanism of asexual reproduction is controlled in lower and higher plants by overlapping sets of genes. To this end, we created a normalized subtracted cDNA library that represents genes with increased expression during apogamy commitment in the fern Ceratopteris richardii. The cDNA library consists of 170 unique sequences. Compared to the mature gametophyte transcriptome of the fern Pteridium aquilinum, the apogamy library is enriched in plant GO-Slim terms that are associated with stress and metabolism. In silico expression analyses of the closest Arabidopsis homologs of the apogamy library revealed many genes that display preferential expression in seed and flower tissues, structures that are absent in ferns. This apogamy library provides a rich resource for investigations into the genetic control of apogamy in ferns and comparisons with the asexual processes of higher plants.
