Genetic transformation and regeneration of Sesbania drummondii using cotyledonary nodes.
Article in Plant cell reports, 2009. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
Sesbania drummondii (Rydb.) Cory is a source for phytopharmaceuticals. It also hyperaccumulates several toxic heavy metals. Development of an efficient gene transfer method is an absolute requirement for the genetic improvement of this plant with more desirable traits due to limitations in conventional breeding methods. A simple protocol was developed for Agrobacterium-mediated stable genetic transformation of Sesbania. Agrobacterium tumefaciens strain EHA 101 containing the vector pCAMBIA 1305.1 having hptII and GUS plus genes was used for the gene transfer experiments. Evaluation of various parameters was carried out to assess the transformation frequency by GUS expression analysis. High transformation frequency was achieved by using 7-day-old precultured cotyledonary node (CN) explants. Further, the presence of acetosyringone (150 muM), infection of explants for 30-45 min and 3 days of cocultivation proved to be critical factors for greatly improving the transformation efficiency. Stable transformation of S. drummondii was achieved, and putative transgenic shoots were obtained on medium supplemented with hygromycin (25 mg l(-1)). GUS histochemical analysis of the putative transgenic tissues further confirmed the transformation event. Genomic Southern blot analysis was performed to verify the presence of transgenes and their stable integration. A transformation frequency of 4% was achieved for CN explants using this protocol.
