Biocontrol Streptomyces Induces Resistance to Bacterial Wilt by Increasing Defense-Related Enzyme Activity in Solanum melongena L.
Article in Current microbiology, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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
Streptomyces strains were isolated from rhizosphere soil and evaluated for in vitro plant growth and antagonistic potential against Ralstonia solanacearum. Based on their in vitro screening, seven Streptomyces were evaluated for plant growth promotion (PGP) and biocontrol efficacy by in-planta and pot culture study. In the in-planta study, Streptomyces-treated eggplant seeds showed better germination percentage, plant growth, and disease occurrence against R. solanacearum than the control treatment. Hence, all seven Streptomyces cultures were developed as a bioformulation by farmyard manure and used for pot culture study. The highest plant growth, weight, and total chlorophyll content were observed in UP1A-1-treated eggplant followed by UP1A-4, UT4A-49, and UT6A-57. Similarly, the maximum biocontrol efficacy was observed in UP1A-1-treated eggplants against bacterial wilt. The biocontrol potential of Streptomyces is also confirmed through metabolic responses by assessing the activities of the defense-related enzymes peroxidase (POX), polyphenol oxidase (PPO), and phenylalanine ammonia-lyase (PAL) and as well as the levels of total phenol. Treatment with UP1A-1/ UT4A-49 and challenge with R. solanacearum led to maximum changes in the activities of POX, PPO, and PAL and the levels of total phenol in the eggplants at different time intervals. Alterations in enzymes of UP1A-1 treatment were related to early defense responses in eggplant. Therefore, the treatment with UP1A-1 significantly delayed the establishment of bacterial wilt in eggplant. Altogether, the present study suggested that the treatment of Streptomyces maritimus UP1A-1 fortified farmyard manure has improved the plant growth and stronger disease control against R. solanacearum on eggplant.
