A polymorphic pseudoautosomal boundary in the Carica papaya sex chromosomes.
Article in Molecular genetics and genomics : MGG, 2015. 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
Sex chromosomes are defined by a non-recombining sex-determining region (SDR) flanked by one or two pseudoautosomal regions (PARs). The genetic composition and evolutionary dynamics of the PAR is also influenced by its linkage to the differentiated non-recombining SDR; however, understanding the effects of this linkage requires a precise definition of the PAR boundary. Here, we took a molecular population genetic approach to further refine the location of the PAR boundary of the evolutionary young sex chromosomes of the tropical plant, Carica papaya. We were able to map the position of the papaya PAR boundary A to a 100-kb region between two genetic loci approximately 2 Mb upstream of the previously genetically identified PAR boundary. Furthermore, this boundary is polymorphic within natural populations of papaya, with an approximately 100-130 kb expansion of the non-recombining SDR found in 16 % of individuals surveyed. The expansion of the PAR boundary in one Y haplotype includes at least one additional gene. Homologs of this gene are involved in male gametophyte and pollen development in other plant species.
