Identification and characterization of the RCI2 gene family in maize (Zea mays).
Article in Journal of genetics, 2014. 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
Rare-cold-inducible (RCI2) genes are structurally conserved members that encode small, highly hydrophobic proteins involved in response to various abiotic stresses. Phylogenetic and functional analyses of these genes have been conducted in Arabidopsis, but an extensive investigation of the RCI2 gene family has not yet been carried out in maize. In the present study, 10 RCI2 genes were identified in a fully sequenced maize genome. Structural characterization and expression pattern analysis of 10 ZmRCI2s (Zea mays RCI2 genes) were subsequently determined. Sequence and phylogenetic analyses indicated that ZmRCI2s are highly conserved, and most of them could be grouped with their orthologues from other organisms. Chromosomal location analysis indicated that ZmRCI2s were distributed unevenly on seven chromosomes with two segmental duplication events, suggesting that maize RCI2 gene family is an evolutionarily conserved family. Putative stress-responsive cis-elements were detected in the 2-kb promoter regions of the 10 ZmRCI2s. In addition, the 10 ZmRCI2s showed different expression patterns in maize development based on transcriptome analysis. Further, microarray and quantitative real-time PCR (qRT-PCR) analysis showed that each maize RCI2 genes were responsive to drought stress, suggesting their important roles in drought stress response. The results of this work provide a basis for future cloning and application studies of maize RCI2 genes.
