Rice CYP734A cytochrome P450s inactivate brassinosteroids in Arabidopsis.
Article in Planta, 2011. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 18 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
Endogenous brassinosteroid concentrations are an important target for optimizing the growth of crop plants because these hormones influence yield and stress tolerance. The CYP734A subfamily of cytochrome P450 enzymes has been shown to inactivate brassinosteroid hormones in Arabidopsis and tomato. Rice has three genes for CYP734A enzymes whose expression appears to be up-regulated by exogenous brassinolide. The amino acids predicted to be in the active site of the rice enzymes vary when compared with the Arabidopsis protein sequence, suggesting that there could be differences in their ability to inactivate the hormone. We have cloned three CYP734A rice genes and expressed them in Arabidopsis to assess their efficacy as brassinosteroid-inactivating enzymes. We found that incorrect transcript splicing can complicate the expression of monocot genomic clones in a eudicot. However, the Arabidopsis system allowed us to characterize an atypical splice variant in one of the rice genes. cDNA clones produced high levels of expression and conferred the brassinosteroid inactivation phenotype. This study shows that Arabidopsis is a useful heterologous system for testing plant genes predicted to act in biochemical pathways that are conserved between monocots and eudicots.
