Two different signaling pathways for thaxtomin A-induced cell death in Arabidopsis and tobacco BY2.
Article in Plant signaling & behavior, 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
Thaxtomin A (TXT) is a phytotoxin produced by all plant-pathogenic Streptomyces scabies involved in the potato scab disease. Their pathogenicity was previously correlated with the production of TXT. Calcium is known to be an essential second messenger associated with pathogen-induced plant responses and cell death. We have effectively shown that in Arabidopsis thaliana cell suspensions, TXT induces an early short lived Ca(2+) influx which is involved in the cell death process and other TXT-induced responses. We extended our study to Nicotiana tabacum BY2 by monitoring cell death and changes in cytosolic calcium concentration on cells expressing the apoaequorine Ca(2+) reporter protein to compare the responses to TXT of the two model plants, tobacco and A. thaliana. Our investigations show that cell death in BY2 appeared to be dose dependent with a lag of sensitivity comparing to A. thaliana. Moreover, pathway leading to cell death in BY2 does not involve calcium signaling. Our results suggest that different pathways are engaged in A. thaliana and N. tabacum BY2 to achieve the same response to TXT.
