Fine mapping and candidate gene analysis of a novel fertility restorer gene for C-type cytoplasmic male sterility in maize (Zea mays L.).
Article in TAG. Theoretical and applied genetics. Theoretische und angewandte Genetik, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
key messageA novel strong fertility restorer gene Rf12 for C-type cytoplasmic male sterility of maize was finely mapped on chromosome 2. Its best candidate gene Zm00001d007531 is predicted to encode a p-type PPR protein. The lack of strong restorer gene of maize CMS-C greatly limits its application in hybrid seed production. Therefore, the cloning of maize CMS-C novel strong restorer genes is necessary. In this study, a strong restorer line ZH91 for maize CMS-C was found, and the novel restorer gene named Rf12 in ZH91 had been mapped in a 146 kb physical interval on maize chromosome 2. Using the third-generation high-throughput sequencing (ONT), the whole genome sequence of ZH91 was got, and with integrating the annotation information of the reference genome B73_RefGen_v4 and B73_RefGen_v5, four candidate genes were predicted in ZH91 within the mapping region. Then using gene cloning, stranded specific RNA sequencing, qRT-PCR analysis and subcellular localization, Zm00001d007531 was identified as the most likely candidate gene of Rf12. Zm00001d007531 encodes a p-type PPR protein with 19 PPR motifs and targets mitochondria and chloroplast. Stranded specific RNA sequencing and qRT-PCR results both show that the expression of Zm00001d007531 between anthers of near-isogenic lines C478
