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

S-cytoplasm is the most common source of cytoplasmic-genic male sterility (CMS) used to produce hybrid-onion seed. Identification of the cytoplasm of a single plant takes from 4 to 8 years and is complicated by the segregation of a nuclear gene that restores fertility. Although CMS in onion may be due to an incompatibility between the mitochondrial and nuclear genomes, Southern analyses of DNA from individual plants from crosses of S- and N-cytoplasmic plants supported maternal inheritance of the chloroplast and mitochondrial DNA and, therefore, polymorphisms in the chloroplast DNA may be used to classify cytoplasms. Amplification by the polymerase chain reaction of a fragment that carries an autapomorphic 100-bp insertion in the chloroplast DNA of N-cytoplasm offers a significantly quicker and cheaper alternative to crossing or Southern analysis. Molecular characterization of N- and S-cytoplasms and frequencies of the nuclear non-restoring allele allow onion breeders to determine the proportion of plants in open-pollinated populations that maintain CMS and can significantly reduce the investment required to identify individual maintainer plants.
