A gene block causing cross-incompatibility hidden in wild and cultivated rice.
Article in Genetics, 2003. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 20 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
Unidirectional cross-incompatibility was detected in advanced generations of backcrossing between wild (Oryza rufipogon) and cultivated (O. sativa) rice strains. The near-isogenic line (NIL) of T65wx (Japonica type) carrying an alien segment of chromosome 6 from a wild strain gave a reduced seed setting only when crossed with T65wx as the male. Cytological observations showed that abortion of hybrid seeds occurred as a consequence of a failure of early endosperm development followed by abnormalities in embryo development. The genetic basis of cross-incompatibility reactions in the female and male was investigated by testcrosses using recombinant inbred lines (RILs) that were established through dissecting the introgressed segments of wild and cultivated (Indica type) strains. The results revealed that the cross-incompatibility reaction was controlled by Cif in the female and by cim in the male. When the female plant with Cif was crossed with the male plant with cim, a failure of early endosperm development was observed in the hybrid zygotes. Among cultivars of O. sativa, cim was distributed predominantly in the Japonica type but not in the Indica type. In addition, a dominant suppressor, Su-Cif, which changes the reaction in the female from incompatible to compatible was proposed to present near the centromere of chromosome 6 of the Indica type. Further, the death of young F(1) zygotes was controlled by the parental genotypes rather than by the genotype of the hybrid zygote itself since all three genes acted sporophytically, which strongly suggests an involvement of parent-of-origin effects. We discuss the results in relation to the origin of a crossing barrier as well as their maintenance within the primary gene pool.
