Fine mapping of wheat powdery mildew resistance gene Pm6 using 2B/2G homoeologous recombinants induced by the ph1b mutant.
Article in TAG. Theoretical and applied genetics. Theoretische und angewandte Genetik, 2020. 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
key messageUsing the ph1b mutant, the recombination frequency between the homoeologous region of 2B and 2G was significantly increased. By this, we narrowed Pm6 to a 0.9 Mb physical region. The powdery mildew (Pm) resistance gene Pm6 from Triticum timopheevii (2n = 48, AAGG) was mapped to the long arm of chromosome 2G and introduced into common wheat in the form of 2B-2G introgressions. The introgression line IGV1-465 has the shortest 2G segment, which is estimated 37 Mb in size when referring to 2BL genome reference of Chinese Spring (CS). The further fine mapping of Pm6 was impeded by the inhibition of allogeneic chromosome recombination between 2B and 2G in the Pm6 region. In the present study, to overcome 2B/2G recombination suppression, a ph1b-based strategy was employed to produce introgressions with reduced 2G fragments for the fine mapping of Pm6. IGV1-465 was crossed and backcrossed to the CSph1b mutant to produce plants with increased 2B/2G chromosome pairing frequency at the Pm6 region. A total of 182 allogeneic recombinants were obtained through two-round screening, i.e., first round of screening of 820 BC
