1 · What the graph read from it

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.

2 · The registry

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

Analysis of chromosome pairing has been an important tool to assess the genetic similarity of homologous and homoeologous chromosomes in polyploids. However, it is technically challenging to monitor the pairing of specific chromosomes in polyploid species, especially for plant species with a large number of small chromosomes. We developed oligonucleotide-based painting probes for four different potato chromosomes. We demonstrate that these probes are robust enough to monitor a single chromosome throughout the prophase I of meiosis in polyploid Solanum species. Cultivated potato (Solanum tuberosum, 2n = 4x = 48) is an autotetraploid. We demonstrate that the four copies of each potato chromosome pair as a quadrivalent in 66-78% of the meiotic cells at the pachytene stage. Solanum demissum (2n = 6x = 72) is a hexaploid and has been controversial regarding its nature as an autopolyploid or allopolyploid. Interestingly, no hexavalent pairing was observed in meiosis. Instead, we observed three independent bivalents in 83-98% of the meiotic cells at late diakinesis and early metaphase I for the four chromosomes. These results suggest that S. demissum has evolved into a cytologically stable state with predominantly bivalent pairing in meiosis.
