Binding of the PTA1 transcriptional activator to the divergent promoter region of the first two genes of the penicillin pathway in different Penicillium species.
Article in Current genetics, 2007. 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
The aim of this work is to establish the correlation between the transcriptional activator PTA1 and the expression of the penicillin genes in different penicillin-producing strains. The level of expression of the first two genes of the penicillin pathway was clearly higher in Penicillium chrysogenum than in Penicillium notatum and Penicillium nalgiovense. The divergent promoter pcbAB-pcbC region contains binding sequences for several transcriptional factors that are conserved in P. notatum and P. chrysogenum, but not in P. nalgiovense. Binding of the purified P. chrysogenum transcriptional activator PTA1 to the palindromic heptamer TTAGTAA took place when the P. chrysogenum 35 bp DNA fragment containing the heptamer was used as a probe, but not when the sequence occurring in P. nalgiovense was used. P. nalgiovense protein fractions purified by heparin agarose chromatography did not bind to the 35-bp DNA fragment either from P. nalgiovense or P. chrysogenum, although some degree of binding was observed when crude extracts were used. This finding may explain the low expression of pcbC in P. nalgiovense. All the P. chrysogenum strains, including the industrial strain E1, showed the same nucleotide sequence, including the consensus PTA1 binding site.
