A set of vectors and strains for chromosomal integration in fission yeast.
Article in Scientific reports, 2023. 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
The expression of heterologous genes is an important technique in yeast genetics. In fission yeast, the leu1 and ura4 genes have been used mainly as selectable markers for heterologous expression. To expand the repertoire of selection markers available for heterologous expression of genes, here we developed new host-vector systems employing lys1 and arg3. By employing genome editing with the CRISPR/Cas9 system, we isolated several alleles of lys1 and arg3, each having a critical mutation in the ORF region. In parallel, we developed a set of vectors that complement the amino acid auxotrophy of lys1 and arg3 mutants when integrated into each locus. Using these vectors in combination with the previously developed integration vector pDUAL, we successfully observed the localization of three proteins in a cell simultaneously by fusing them with different fluorescent proteins. Thus, these vectors enable combinatorial expression of heterologous genes, which addresses increasingly diverse experimental challenges.
