The chloroplast and mitochondrial genome sequences of the charophyte Chaetosphaeridium globosum: insights into the timing of the events that restructured organelle DNAs within the green algal lineage that led to land plants.

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
The land plants and their immediate green algal ancestors, the charophytes, form the Streptophyta. There is evidence that both the chloroplast DNA (cpDNA) and mitochondrial DNA (mtDNA) underwent substantial changes in their architecture (intron insertions, gene losses, scrambling in gene order, and genome expansion in the case of mtDNA) during the evolution of streptophytes; however, because no charophyte organelle DNAs have been sequenced completely thus far, the suite of events that shaped streptophyte organelle genomes remains largely unknown. Here, we have determined the complete cpDNA (131,183 bp) and mtDNA (56,574 bp) sequences of the charophyte Chaetosphaeridium globosum (Coleochaetales). At the levels of gene content (124 genes), intron composition (18 introns), and gene order, Chaetosphaeridium cpDNA is remarkably similar to land-plant cpDNAs, implying that most of the features characteristic of land-plant lineages were gained during the evolution of charophytes. Although the gene content of Chaetosphaeridium mtDNA (67 genes) closely resembles that of the bryophyte Marchantia polymorpha (69 genes), this charophyte mtDNA differs substantially from its land-plant relatives at the levels of size, intron composition (11 introns), and gene order. Our finding that it shares only one intron with its land-plant counterparts supports the idea that the vast majority of mitochondrial introns in land plants appeared after the emergence of these organisms. Our results also suggest that the events accounting for the spacious intergenic spacers found in land-plant mtDNAs took place late during the evolution of charophytes or coincided with the transition from charophytes to land plants.
