Multiple fertility restorer loci for cytoplasmic male sterility caused by mitochondrial gene orf137 in tomato.
Article in Journal of experimental botany, 2025. 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
Cytoplasmic male sterility (CMS) in plants is caused by incompatibility between nuclear and cytoplasmic genetic information. Fertility can be restored through the action of fertility restorer (RF) genes, which are usually present in the nucleus. CMS lines of tomato (Solanum lycopersicum) caused by mitochondrial gene orf137 have been developed from asymmetric cell fusions, and in these lines, cultivated tomato served as a nuclear donor and its wild relative, S. acaule, as a cytoplasm donor. Although RF genes are present in wild relatives of tomato, no genetic or genomic information on the RF genes is yet available. This study reports an RF genetic locus, RF1, on chromosome 1 of S. pimpinellifolium LA1670 and S. lycopersicum var. cerasiforme LA1673, which was revealed by bulked segregant analysis and sequencing. An additional RF locus, RF2, was identified on chromosome 2 of LA1670. The genomic sequence of S. cheesmaniae LA0166 was assembled using high-fidelity, long-read sequencing technology. Sequence comparisons identified further candidate RF genes on chromosome 1 of S. cheesmaniae LA0166. These results suggested that multiple gene loci control the fertility restoration trait in wild relatives of tomato.
