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

In this study, we present a method for transient expression of the type III effector AvrGf1 from Xanthomonas citri subsp. citri strain A(w) in grapefruit leaves (Citrus paradisi) via Agrobacterium tumefaciens. The coding sequence of avrGf1 was placed under the control of the constitutive CaMV 35S promoter in the binary vectors pGWB2 and pGWB5. Infiltration of grapefruit leaves with A. tumefaciens carrying these constructs triggered a hypersensitive response (HR) in grapefruit 4 days after inoculation. When transiently expressed in grapefruit leaves, two mutants, AvrGf1ΔN116 and AvrGf1ΔC83, failed to induce an HR. Moreover, using bioinformatics tools, a chloroplast transit signal was predicted at the N terminus of AvrGf1. We demonstrated chloroplast localization by using an AvrGf1::GFP fusion protein, where confocal images revealed that GFP fluorescence was accumulating in the stomatal cells that are abundant in chloroplasts. Transient expression in citrus has the potential for aiding in the development of new disease defense strategies in citrus.
