Cloning and characterization of TaVIP2 gene from Triticum aestivum and functional analysis in Nicotiana tabacum.
Article in Scientific reports, 2016. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
Wheat is recalcitrant to genetic transformation. A potential solution is to manipulate the expression of some host proteins involved in T-DNA integration process. VirE2 interacting protein 2 (VIP2) plays an important role in T-DNA transport and integration. In this study, a TaVIP2 gene was cloned from common wheat. Southern blot and allele-specific polymerase chain reaction (AS-PCR) combined with an online chromosomal location software tool revealed that three TaVIP2 genes were located on wheat chromosomes 1AL, 1BL, and 1DL. These three homoeoallelic TaVIP2 genes all contained 13 exons and 12 introns, and their coding sequences were the same; there were a few single nucleotide polymorphisms (SNPs) among the three genes. The heterologous expression of the TaVIP2 gene in tobacco led to enhancement of the Agrobacterium-mediated transformation efficiency up to 2.5-fold. Transgenic tobacco plants expressing TaVIP2 showed enhanced resistance to powdery mildew. Further quantitative real-time PCR (qRT-PCR) revealed that overexpression of TaVIP2 in transgenic tobacco up-regulated the expression of an endogenous gene, NtPR-1, which likely contributed to powdery mildew resistance in transgenic tobacco. Our study indicates that the TaVIP2 gene may be highly useful in efforts to improve Agrobacterium-mediated transformation efficiency and to enhance powdery mildew resistance in wheat.
