Identification of plasmids from thermophilic Streptomyces strains and development of a gene cloning system for thermophilic Streptomyces species.
Article in Journal of industrial microbiology & biotechnology, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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 host-vector system for use in thermophilic Streptomyces, multi-copy plasmids were screened for thermophilic Streptomyces species using data from public bioresource centers (JCM and NBRC). Of 27 thermophilic Streptomyces strains, 3 harbored plasmids. One plasmid (pSTVU1), derived from S. thermovulgaris NBRC 16615 (= JCM 4520, ATCC 19284, DSM 40444, ISP 5444, NRRL B-12375, and NCIMB 10078), was multi-copy and relatively small in size. Analysis of the sequence of this multi-copy plasmid revealed that it was 7,838 bp and contained at least 10 predicted open reading frames. The plasmid was introduced into 14 thermophilic Streptomyces strains (of 18 strains examined) and several mesophilic Streptomyces strains (S.lividans, S.parvulus, and S.avermitilis). pSTVU1 can be transferred by mixed culture because the plasmid encodes the ORF that regulates the transfer function. Plasmid transfer was observed not only between strains within the same species but also between mesophilic Streptomyces and thermophilic Streptomyces (and vice versa); however, the efficiency of this transfer was extremely low. We also confirmed that a derivative of pSTVU1 can be used as a multi-copy vector in the gene expression system that is expected to exhibit gene-dosage effects, establishing a method for efficient production of thermophilic α-amylase. ONE-SENTENCE SUMMARY: A multi-copy plasmid was identified in thermophilic Streptomyces and used to develop a gene cloning system for thermophilic Streptomyces species.
