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

We analysed the products of male meiosis in microspore-derived progeny from a Brassica napus (AAC(n)C(n)) x Brassica carinata (BBC(c)C(c)) interspecific hybrid (ABC(n)C(c)). Genotyping at 102 microsatellite marker loci and nuclear DNA contents provided strong evidence that 26 of the 28 progeny (93%) were derived from unreduced (2n) gametes. The high level of C(n)C(c) marker heterozygosity, and parallel spindles at Anaphase II in the ABC(n)C(c) hybrid, indicated that unreduced gametes were formed by first division restitution. The frequency of dyads at the tetrad stage of pollen development (2.6%) suggested that unreduced gametes were preferentially selected in microspore culture. Segregation of marker alleles in the microspore-derived progeny was consistent with homologous recombination between C(n) and C(c) chromosomes and homoeologous recombination involving A-, B- and C-genome chromosomes during meiosis in the ABC(n)C(c) hybrid. We discuss the potential for using microspore culture of unreduced gametes in interspecific hybrids to map Brassica centromeres through half-tetrad analysis.
