Characterization of an RNA silencing suppressor encoded by maize yellow dwarf virus-RMV2.
Article in Virus genes, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
Maize yellow dwarf virus-RMV2 (MYDV-RMV2) causes dwarfing and yellowing symptoms on leaves in field-grown maize plants in Anhui province in China. Herein, we evaluated the RNA silencing suppressor (RSS) activity of the P0 protein from MYDV-RMV2 by co-infiltration assays using wild-type and GFP-transgenic Nicotiana benthamiana (line 16C). The P0 of MYDV-RMV2 exhibited RSS activity and inhibited RNA silencing both locally and systemically. MYDV-RMV2 P0 acts as an F-box-like motif, and mutations to Ala at positions 67, 68, and 81 in the F-box-like motif (67LPxx81P) abolished the RSS activity of P0. However, MYDV-RMV2 P0 failed to interact with AGO1 from Arabidopsis thaliana. Expressing P0 induced developmental defects. P0 was targeted to both the nuclei and cytoplasm of plant cells. These findings expand our knowledge of the role of polerovirus P0 proteins in RNA silencing.
