Chromosome Painting Using Chromosome-Specific BAC Clones.

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
Chromosome painting (CP) refers to visualization of large chromosome regions, chromosome arms or entire chromosomes via fluorescence in situ hybridization (FISH) of chromosome-specific DNA sequences. For CP in crucifers (Brassicaceae), typically contigs of chromosome-specific bacterial artificial chromosomes (BAC) from Arabidopsis thaliana are applied as painting probes on chromosomes of A. thaliana or other species (comparative chromosome painting, CCP). CP/CCP enables to identify and trace particular chromosome regions and/or chromosomes throughout all mitotic and meiotic stages as well as corresponding interphase chromosome territories. However, extended pachytene chromosomes provide the highest resolution of CP/CCP. Fine-scale chromosome structure, structural chromosome rearrangements (such as inversions, translocations, centromere repositioning), and chromosome breakpoints can be investigated by CP/CCP. BAC DNA probes can be accompanied by other types of DNA probes, such as repetitive DNA, genomic DNA, or synthetic oligonucleotide probes. Here, we describe a robust step-by-step protocol of CP and CCP which proved to be efficient across the family Brassicaceae, but which is also applicable to other angiosperm families.
