Impacts of Whole-Genome Triplication on MIRNA Evolution in Brassica rapa.
Article in Genome biology and evolution, 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 15 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
MicroRNAs (miRNAs) are a class of short non-coding, endogenous RNAs that play essential roles in eukaryotes. Although the influence of whole-genome triplication (WGT) on protein-coding genes has been well documented in Brassica rapa, little is known about its impacts on MIRNAs. In this study, through generating a comprehensive annotation of 680 MIRNAs for B. rapa, we analyzed the evolutionary characteristics of these MIRNAs from different aspects in B. rapa. First, while MIRNAs and genes show similar patterns of biased distribution among subgenomes of B. rapa, we found that MIRNAs are much more overretained than genes following fractionation after WGT. Second, multiple-copy MIRNAs show significant sequence conservation than that of single-copy MIRNAs, which is opposite to that of genes. This indicates that increased purifying selection is acting upon these highly retained multiple-copy MIRNAs and their functional importance over singleton MIRNAs. Furthermore, we found the extensive divergence between pairs of miRNAs and their target genes following the WGT in B. rapa. In summary, our study provides a valuable resource for exploring MIRNA in B. rapa and highlights the impacts of WGT on the evolution of MIRNA.
