A quick and efficient system for antibiotic-free expression of heterologous genes in tobacco roots.
Article in Plant cell reports, 2004. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 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
Requirement for antibiotic-resistance selection markers and difficulty in identifying transgenes with the highest expression levels remain the major obstacles for rapid production of recombinant proteins in plants. An alternative approach to producing transgenic plants free of antibiotic-resistance markers is the phenotypic-based selection with root-proliferation genes (rol genes) of Agrobacterium rhizogenes. By using Agrobacterium tumefaciens harboring the pRYG transformation vector with a cluster of rol genes linked to a heterologous gene of interest, we have developed a rapid transformation tool using hairy root formation as a selection marker. The expression of beta-glucuronidase in newly induced transgenic tobacco roots could be detected as early as 12 days after inoculation. Higher levels of transgene expression in the roots correlated positively with the rates of root elongation on hormone-free medium and thus could be used for positive selection. When tobacco plants were transformed with pRYG harboring the expression cassette for secreted alkaline phosphatase (SEAP), the release of SEAP from roots of the fully regenerated transgenic plants could be quantified at rates as high as 28 microg/g root dry weight per day.
