Identification and characterization of Dicer-like, Argonaute and RNA-dependent RNA polymerase gene families in maize.
Article in Plant cell reports, 2011. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 74 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
Eukaryotic gene expression is regulated at least by two processes, RNA interference at the post-transcriptional level and chromatin modification at the transcriptional level. Distinct small RNAs (approximately 21-24 nucleotides; sRNAs) were demonstrated to play vital roles in facilitating gene silencing. In plants, the generation of these sRNAs mainly depends on some proteins encoded by respective Dicer-like (DCL), Argonaute (AGO) and RNA-dependent RNA polymerases (RDR) gene families. Here, we analyzed the DCL, AGO and RDR gene families in maize, including gene structure, phylogenetic relationships, protein conserved motifs and genomic localization among gene family members. A total of 5 Zmdcl, 18 Zmago and 5 Zmrdr genes were identified in maize. Phylogenetic analyses clustered each of these genes families into four subfamilies. In addition, gene chromosomal localization revealed that five pairs of Zmago genes resulted from tandem or segmental duplication, respectively. EST expression data mining revealed that these newly identified genes had temporal and spatial expression pattern. Furthermore, the transcripts of these genes were detected in the leaves by two different abiotic stress treatments using semi-quantitative RT-PCR. The data demonstrated that these genes exhibited different expression levels in stress treatments. The results of this study provided basic genomic information for these gene families and insights into the probable roles of these genes in plant growth and development. This will further provide a solid foundation for future functional genomics studies of Dicer-like, Argonaute and RDR gene families in maize.
