Deletion of a 236 kb region around S 4-RNase in a stylar-part mutant S 4sm-haplotype of Japanese pear.
Article in Plant molecular biology, 2008. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 32 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
Japanese pear (Pyrus pyrifolia Nakai) has a gametophytic self-incompatibility (GSI) mechanism controlled by a single S-locus with multiple S-haplotypes, each of which contains separate genes that determine the allelic identity of pistil and pollen. The pistil S gene is the S-ribonuclease (S-RNase) gene, whereas good candidates for the pollen S gene are the F-box protein genes. A self-compatible (SC) cultivar, 'Osa-Nijisseiki', which is a bud mutant of 'Nijisseiki' (S (2) S (4)), has a stylar-part mutant S(4)sm-haplotype, which lacks the S (4)-RNase gene but retains the pollen S gene. To delineate the deletion breakpoint in the S(4)sm-haplotype, we constructed a bacterial artificial chromosome (BAC) library from an S (4)-homozygote, and assembled a BAC contig of 570 kb around the S (4)-RNase. Genomic PCR of DNA from S (4)- and S(4)sm-homozygotes and the DNA sequence of the BAC contig allowed the identification of a deletion of 236 kb spanning from 48 kb upstream to 188 kb downstream of S (4)-RNase. The S(4)sm-haplotype lacks 34 predicted open reading frames (ORFs) including the S (4)-RNase and a pollen-specific F-box protein gene (termed as S (4) F-box0). Genomic PCR with a primer pair designed from the deletion junctions yielded a product specific for the S(4)sm-haplotype. The product could be useful as a maker for early selection of SC cultivars harboring the S(4)sm-haplotype.
