A reference high-density genetic map of greater yam (Dioscorea alata L.).
Article in TAG. Theoretical and applied genetics. Theoretische und angewandte Genetik, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 34 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 messageThis study generated the first high-density genetic map for D. alata based on genotyping-by-sequencing and provides new insight on sex determination in yam. Greater yam (Dioscorea alata L.) is a major staple food in tropical and subtropical areas. This study aimed to produce the first reference genetic map of this dioecious species using genotyping-by-sequencing. In this high-density map combining information of two F1 outcrossed populations, 20 linkage groups were resolved as expected and 1579 polymorphic markers were ordered. The consensus map length was 2613.5 cM with an average SNP interval of 1.68 cM. An XX/XY sex determination system was identified on LG6 via the study of sex ratio, homology of parental linkage groups and the identification of a major QTL for sex determination. Homology with the sequenced D. rotundata is described, and the median physical distance between SNPs was estimated at 139.1 kb. The effects of segregation distortion and the presence of heteromorphic sex chromosomes are discussed. This D. alata linkage map associated with the available genomic resources will facilitate quantitative trait mapping, marker-assisted selection and evolutionary studies in the important yet scarcely studied yam species.
