The first genetic linkage map for Fraxinus pennsylvanica and syntenic relationships with four related species.
Article in Plant molecular biology, 2019. 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
key messageThe genetic linkage map for green ash (Fraxinus pennsylvanica) contains 1201 DNA markers in 23 linkage groups spanning 2008.87cM. The green ash map shows stronger synteny with coffee than tomato. Green ash (Fraxinus pennsylvanica) is an outcrossing, diploid (2n = 46) hardwood tree species, native to North America. Native ash species in North America are being threatened by the rapid spread of the emerald ash borer (EAB, Agrilus planipennis), an invasive pest from Asia. Green ash, the most widely distributed ash species, is severely affected by EAB infestation, yet few genomic resources for genetic studies and improvement of green ash are available. In this study, a total of 5712 high quality single nucleotide polymorphisms (SNPs) were discovered using a minimum allele frequency of 1% across the entire genome through genotyping-by-sequencing. We also screened hundreds of genomic- and EST-based microsatellite markers (SSRs) from previous de novo assemblies (Staton et al., PLoS ONE 10:e0145031, 2015; Lane et al., BMC Genom 17:702, 2016). A first genetic linkage map of green ash was constructed from 90 individuals in a full-sib family, combining 2719 SNP and 84 SSR segregating markers among the parental maps. The consensus SNP and SSR map contains a total of 1201 markers in 23 linkage groups spanning 2008.87 cM, at an average inter-marker distance of 1.67 cM with a minimum logarithm of odds of 6 and maximum recombination fraction of 0.40. Comparisons of the organization the green ash map with the genomes of asterid species coffee and tomato, and genomes of the rosid species poplar and peach, showed areas of conserved gene order, with overall synteny strongest with coffee.
