Functional analysis of the GRMZM2G174449 promoter to identify Rhizoctonia solani-inducible cis-elements in maize.
Article in BMC plant biology, 2017. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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
backgroundBanded leaf and sheath blight (BLSB), caused by the necrotrophic fungus Rhizoctonia solani, is a highly devastating disease in most maize and rice growing areas of the world. However, the molecular mechanisms of perceiving pathogen signals are poorly understood in hosts.
resultsHere, we identified a Rhizoctonia solani-inducible promoter pGRMZM2G174449 in maize. Deletion analysis showed that the -574 to -455 fragment was necessary for pGRMZM2G174449 in responding to R. solani and this fragment contained the unknown pathogen-inducible cis-elements according to the bioinformatics analysis. Furthermore, detailed quantitative assays showed that two cis-elements, GCTGA in the -567 to -563 region and TATAT in the -485 to -481 region, were specifically responsible for the R. solani-inducible activity. A series of point mutation analysis indicated that the two cis-elements have the conserved motifs of NHWGN and DWYWT, respectively.
conclusionOur results indicated that pGRMZM2G174449 is a good R. solani-inducible promoter suitable for genetic engineering of BLSB resistance. And NHWGN and DWYWT are two R. solani-inducible cis-elements that play important roles in pGRMZM2G174449 responding to R. solani.
