Modulation of the polyamine biosynthetic pathway in transgenic rice confers tolerance to drought stress.
Article in Proceedings of the National Academy of Sciences of the United States of America, 2004. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 155 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
We have generated transgenic rice plants expressing the Datura stramonium adc gene and investigated their response to drought stress. We monitored the steady-state mRNA levels of genes involved in polyamine biosynthesis (Datura adc, rice adc, and rice samdc) and polyamine levels. Wild-type plants responded to the onset of drought stress by increasing endogenous putrescine levels, but this was insufficient to trigger the conversion of putrescine into spermidine and spermine (the agents that are believed to protect plants under stress). In contrast, transgenic plants expressing Datura adc produced much higher levels of putrescine under stress, promoting spermidine and spermine synthesis and ultimately protecting the plants from drought. We demonstrate clearly that the manipulation of polyamine biosynthesis in plants can produce drought-tolerant germplasm, and we propose a model consistent with the role of polyamines in the protection of plants against abiotic stress.
