The inhibitory effects of metabolites from Bacillus pumilus on potato virus Y and the induction of early response genes in Nicotiana tabacum.
Article in AMB Express, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
To develop a new antiviral preparation from a microbial source, the halophilic bacterium Bacillus pumilus E303035 was isolated from a soil sample collected at Qarhan Salt Lake in Qinghai, China. The inhibitory activity of an ethyl acetate extract of its fermentation broth was higher than that of an n-butanol extract. After isolation and purification, 9 compounds were obtained: cyclo(L-Leu-L-Pro) (1), cyclo(L-Pro-L-Tyr) (2), Brevianamide F (3), 2-(3-Indolyl) ethanol (4), N-[2-(1H-indol-3-yl) ethyl] acetamide (5), 3, 3-di(1H-indol-3-yl)propane-1,2-diol (6), Lincomycin B (7), dibutylphthalate (8), and p-hydroxyphenethyl alcohol (9). Compounds 1, 5, and 9 showed inhibitory activities against potato virus Y (PVY). Compounds 1, 4, and 9 had significant inhibitory activity against genes HC-pro, P3, and Nib, compound 5 against gene P3, and compounds 1 and 4 against NIa. Compounds 1, 4, 5, and 9 had significant inhibitory activity against genes VPg and 6K1. Active compounds 1, 5, and 9 had various effects on the expression of viral genes related to pathogenesis. Expression of genes cullin and XTH was up-regulated and CP was down-regulated, compared to the positive control. In conclusion, compounds 1, 5, and 9 might be considered as potential antiviral agents for future development.
