S-like ribonuclease gene expression in carnivorous plants.
Article in Planta, 2013. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 20 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
Functions of S-like ribonucleases (RNases) differ considerably from those of S-RNases that function in self-incompatibility. Expression of S-like RNases is usually induced by low nutrition, vermin damage or senescence. However, interestingly, an Australian carnivorous plant Drosera adelae (a sundew), which traps prey with a sticky digestive liquid, abundantly secretes an S-like RNase DA-I in the digestive liquid even in ordinary states. Here, using D. adelae, Dionaea muscipula (Venus flytrap) and Cephalotus follicularis (Australian pitcher plant), we show that carnivorous plants use S-like RNases for carnivory: the gene da-I encoding DA-I and its ortholog cf-I of C. follicularis are highly expressed and constitutively active in each trap/digestion organ, while the ortholog dm-I of D. muscipula becomes highly active after trapping insects. The da-I promoter is unmethylated only in its trap/digestion organ, glandular tentacles (which comprise a small percentage of the weight of the whole plant), but methylated in other organs, which explains the glandular tentacles-specific expression of the gene and indicates a very rare gene regulation system. In contrast, the promoters of dm-I, which shows induced expression, and cf-I, which has constitutive expression, were not methylated in any organs examined. Thus, it seems that the regulatory mechanisms of the da-I, dm-I and cf-I genes differ from each other and do not correlate with the phylogenetic relationship. The current study suggests that under environmental pressure in specific habitats carnivorous plants have managed to evolve their S-like RNase genes to function in carnivory.
