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

In higher plants, dominant mitochondrial mutations are associated with pollen sterility. This phenomenon is known as cytoplasmic male sterility (CMS). It is thought that the disruption in pollen development is a consequence of mitochondrial dysfunction. To provide definitive evidence that expression of an abnormal mitochondrial gene can interrupt pollen development, a CMS-associated mitochondrial DNA sequence from common bean, orf239, was introduced into the tobacco nuclear genome. Several transformants containing the orf239 gene constructs, with or without a mitochondrial targeting sequence, exhibited a semi sterile or male-sterile phenotype. Expression of the gene fusions in transformed anthers was confirmed using RNA gel blotting, ELISA, and light and electron microscopic immunocytochemistry. Immunocytological analysis showed that the ORF239 protein could associate with the cell wall of aberrant developing microspores. This pattern of extracellular localization was earlier observed in the CMS common bean line containing orf239 in the mitochondrial genome. Results presented here demonstrate that ORF239 causes pollen disruption in transgenic tobacco plants and may do so without targeting of the protein to the mitochondrion.
