Development of chloroplast transformation for five species in the genus Nicotiana.

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
Technologies for the stable genetic transformation of the plastid (chloroplast) genome are currently restricted to a small number of species. The development of highly efficient tissue culture, regeneration, and selection procedures represents the major hurdle that needs to be overcome to extend the species range of the transplastomic technology. Here, we report the development of efficient plastid transformation protocols for five species in the genus Nicotiana: the model species N. benthamiana, the tree tobacco N. glauca, the ornamental plants N. langsdorffii and N. longiflora, and the wild species N. otophora. We have optimized medium composition for efficient regeneration from leaf explants in all five species and determined suitable selection conditions for plastid transformation. We successfully isolated multiple transplastomic lines for each species and also generated lines that express the fluorescent reporter protein DsRed. Molecular and genetic analyses confirmed the homoplasmic state of the transplastomic lines and demonstrated maternal inheritance of the transgenes. Our work makes plastid genome engineering available for a set of new species and enables new applications in horticultural research and ecology. It also informs the future development of plastid transformation technology for other species.
