Overlapping alternative sigma factor regulons in the response to singlet oxygen in Rhodobacter sphaeroides.
Article in Journal of bacteriology, 2010. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 43 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
Organisms performing photosynthesis in the presence of oxygen have to cope with the formation of highly reactive singlet oxygen ((1)O(2)) and need to mount an adaptive response to photooxidative stress. Here we show that the alternative sigma factors RpoH(I) and RpoH(II) are both involved in the (1)O(2) response and in the heat stress response in Rhodobacter sphaeroides. We propose RpoH(II) to be the major player in the (1)O(2) response, whereas RpoH(I) is more important for the heat stress response. Mapping of the 5' ends of RpoH(II)- and also RpoH(I)/RpoH(II)-dependent transcripts revealed clear differences in the -10 regions of the putative promoter sequences. By using bioinformatic tools, we extended the RpoH(II) regulon, which includes genes induced by (1)O(2) exposure. These genes encode proteins which are, e.g., involved in methionine sulfoxide reduction and in maintaining the quinone pool. Furthermore, we identified small RNAs which depend on RpoH(I) and RpoH(II) and are likely to contribute to the defense against photooxidative stress and heat stress.
