Restorer genes for different forms of Brassica cytoplasmic male sterility map to a single nuclear locus that modifies transcripts of several mitochondrial genes.

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 oilseed rape plant, Brassica napus, possesses two endogenous male sterile cytoplasms, nap and pol. Previous studies have shown that nuclear restoration of pol cytoplasmic male sterility (CMS) is conditioned by a gene, Rfp, that is also involved in modifying transcripts of the pol CMS-associated orf224/atp6 mtDNA region. We now find that the nap nuclear restorer gene Rfn apparently is identical to Mmt, a gene that conditions the modification of transcripts from several different mtDNA regions, including one that is associated with nap CMS and contains orf222, a chimeric gene related to orf224. Mmt, in turn, is found to be allelic to Rfp, suggesting that restorer genes for the two cytoplasms represent different alleles or haplotypes of a single nuclear locus. This view is supported by restriction fragment length polymorphism mapping studies that indicate that Rfn and Rfp map to the same chromosomal position. Thus, in contrast to CMS in other species, different forms of Brassica CMS are restored by alleles of a single nuclear locus, and the restoration properties of these alleles reflect their involvement in the modification of transcripts of corresponding CMS-associated mtDNA regions. A survey of 51 varieties from 8 Brassica and Sinapis species failed to find evidence of Rfn(Mmt) in other than fertility-restored, nap cytoplasm B. napus. This suggests that Rfn(Mmt) arose in Brassica with nap cytoplasm and that the necessity for fertility restoration may have provided the selective pressure for its origin and maintenance.
