Species-specific abundant retrotransposons elucidate the genomic composition of modern sugarcane cultivars.
Article in Chromosoma, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 13 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
Modern sugarcane cultivars are highly polyploid and derived from the hybridization of Saccharum officinarum and S. spontaneum, thus leading to singularly complex genomes. The complex genome has hindered the study of genomic structures. Here, we adopted a computational strategy to isolate highly repetitive and abundant sequences in either S. officinarum or S. spontaneum and isolated four S. spontaneum-enriched retrotransposons. Fluorescence in situ hybridization (FISH) assays with these repetitive DNA sequences generated whole-genome painting signals for S. spontaneum but not for S. officinarum. We demonstrated that these repetitive sequence-based probes distinguish the parental S. spontaneum genome in hybrids derived from crosses between it and S. officinarum. A cytological analysis of 14 modern sugarcane cultivars revealed that the percentages of chromosomes with introgressive S. spontaneum fragments ranged from 11.9 to 40.9% and substantially exceeded those determined for previously investigated cultivars (5-13%). The comparatively higher percentages of introgressive S. spontaneum fragments detected in the aforementioned cultivars indicate frequent recombination between parental genomes. Here, we present the application of our strategy to isolate species-specific cytological markers. This information may help to elucidate complex plant genomic structures and trace their evolutionary histories.
