Segregation distortion of T-DNA markers linked to the self-incompatibility (S) locus in Petunia hybrida.
Article in Genetics, 2000. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
In plants with a gametophytic self-incompatibility system the specificity of the pollen is determined by the haploid genotype at the self-incompatibility (S) locus. In certain crosses this can lead to the exclusion of half the gametes from the male parent carrying a particular S-allele. This leads to pronounced segregation distortion for any genetic markers that are linked to the S-locus. We have used this approach to identify T-DNA insertions carrying a maize transposable element that are linked to the S-locus of Petunia hybrida. A total of 83 T-DNA insertions were tested for segregation distortion of the selectable marker used during transformation with Agrobacterium. Segregation distortion was observed for 12 T-DNA insertions and at least 8 of these were shown to be in the same linkage group by intercrossing. This indicates that differential transmission of a single locus (S) is probably responsible for all of these examples of T-DNA segregation distortion. The identification of selectable markers in coupling with a functional S-allele will allow the preselection of recombination events around the S-locus in petunia. Our approach provides a general method for identifying transgenes that are linked to gametophytic self-incompatibility loci and provides an opportunity for transposon tagging of the petunia S-locus.
