Diversity and biopotential of Bacillus velezensis strains A6 and P42 against rice blast and bacterial blight of pomegranate.
Article in Archives of microbiology, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 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
Bacillus velezensis is widely known for its inherent biosynthetic potential to produce a wide range of bio-macromolecules and secondary metabolites, including polyketides (PKs) and siderophores, as well as ribosomally and non-ribosomally synthesized peptides. In the present study, we aimed to investigate the bio-macromolecules, such as proteins and peptides of Bacillus velezensis strains, namely A6 and P42 by whole-cell sequencing and highlighted the potential application in controlling phytopathogens. The bioactive compounds, specifically secondary metabolites, were characterized by whole-cell protein profiling, Thin-Layer Chromatography, Infra-Red Spectroscopy, Nuclear Magnetic Resonance, Gas Chromatograph and Electro Spray Liquid Chromatography. Gas Chromatography analysis revealed that the A6 and P42 strains exert different functional groups of compounds, such as aromatic ring, aliphatic, alkene, ketone, amine groups and carboxylic acid. Whole-cell protein profiling of A6 and P42 strains of B. velezensis by nano-ESI LC-MS/MS revealed the presence of 945 and 5303 proteins, respectively. The in vitro evaluation of crude extracts (10%) of A6 and P42 significantly inhibited the rice pathogen, Magnaporthe oryzae (MG01), whereas the cell-free culture filtrate (75%) of strain P42 showed 58.97% inhibition. Similarly, in vitro evaluation of crude extract (10%) of P42 strain inhibited bacterial blight of pomegranate pathogen, Xanthomonas axonopodis pv. punicae, which eventually resulted in a higher inhibition zone of 3 cm, whereas the cell-free extract (75%) of the same strain significantly suppressed the growth of the pathogen with an inhibition zone of 1.48 cm. From the results obtained, the crude secondary metabolites and cell-free filtrates (containing bio-macromolecules) of the strains A6 and P42 of B. velezensis can be employed for controlling the bacterial and fungal pathogens of crop plants.
