Fine mapping of leaf rust resistance gene Rph13 from wild barley.
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 9 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 messageFine mapping of the barley leaf rust resistance locus Rph13 on chromosome 3HL facilitates its use in breeding programs through marker-assisted selection. Barley leaf rust (BLR-caused by Puccinia hordei) is a widespread fungal disease that can be effectively controlled by genetic resistance. There is an ongoing need to both diversify and genetically characterise resistance loci to provide effective and durable control given the ongoing threat of rapidly evolving P. hordei populations. Here, we report on the molecular genetic characterisation of the Rph13 locus, originally derived from wild barley and transferred to barley accession Berac (then referred to as PI 531849). The 2017 reference genome of cv. Morex was used as a road map to rapidly narrow both a genetic and physical intervals around the Rph13 resistance locus. Using recombination-based mapping, we narrowed the physical interval to 116.6 kb on chromosome 3H in a segregating population of a cross of the Rph13 carrying resistant line PI 531849 with the leaf rust-susceptible cultivar Gus. We identified two nucleotide-binding leucine-rich repeat genes as likely candidates for the Rph13 resistance. Sequences from the candidate genes enabled the development of a KASP marker that distinguished resistant and susceptible progeny and was found to be predictive and useful for MAS.
