1 · What the graph read from it

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.

2 · The registry

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

Transient expression of genes using Agrobacterium is a powerful tool for the analysis of gene function in plants. We have developed this method for the analysis of genes involved in disease resistance in grapevine leaves. Our research showed that the quality of the plant material, the plant genotype used for agro-infiltration and the presence of additional virulence factors (carried on plasmid pCH32) in the Agrobacterium strain are all important factors for success of the procedure. After optimising these factors, we consistently achieve sufficient acceptable levels of expression of the markers beta-glucuronidase (GUS) and green fluorescent protein (GFP) using vacuum infiltration of grapevine leaves from plants grown in vitro. We used this procedure to investigate the proposed role of stilbenes in defense against grapevine downy mildew (Plasmopara viticola) by transiently overexpressing stilbene synthase in grapevine leaves, before infection with P. viticola. We found that agro-infiltration itself induces the synthesis of stilbenes in grapevine leaves, thus preventing us to test the effect of the overexpression of stilbene synthase in defense. However, our results revealed that agro-infiltration before P. viticola inoculation had an effect on the development of the infection. Further research is required to show whether stilbenes or some other factor are the causal agent restricting pathogen development. The method described here provides and excellent tool to exploit at the many grapevine genomic resources now available, and will contribute to a better understanding of many areas of grapevine biology.
