Identification of novel broad host-range promoter sequences functional in diverse Pseudomonadota by a promoter-trap approach.
Article in Brazilian journal of microbiology : [publication of the Brazilian Society for Microbiology], 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Finding novel promoter sequences is a cornerstone of synthetic biology. To contribute to the expanding catalog of biological parts, we employed a promoter-trap approach to identify novel sequences within an Antarctic microbial community that act as broad host-range promoters functional in diverse Pseudomonadota. Using Pseudomonas putida KT2440 as host, we generated a library comprising approximately 2,000 clones resulting in the identification of thirteen functional promoter sequences, thereby expanding the genetic toolkit available for this chassis. Some of the discovered promoter sequences prove to be broad host-range as they drove gene expression not only in P. putida KT2440 but also in Escherichia coli DH5α, Cupriavidus taiwanensis R1
