An active photosynthetic electron transfer chain required for mcyD transcription and microcystin synthesis in Microcystis aeruginosa PCC7806.
Article in Ecotoxicology (London, England), 2012. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 13 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
In this study, quantitative real time RT-PCR has been used to monitor changes in the levels of transcripts encoding mcyD in Microcystis aeruginosa PCC7806 under oxidative agents and different conditions of light intensity. Microcystin content has also been determined in the same stressed cell aliquots. Our results corroborate the fact that changes in light intensities are able to induce mcyD gene transcription, but our data show that this is an early and short-term event. mcyD transcription requires an active photosynthetic electron transfer chain and the increased transcript level as a consequence of light is not related to oxidative stress. Indeed, oxidative stress leads to a general trend of a decrease of mcyD trancript. Microcystin amount found in the cells follows a tendency consistent with the mcyD transcript level. In summary, the data indicate that the synthesis of microcystin is dependent on photosynthesis, and also show that oxidative stress decreases the microcystin synthesis in toxigenic Microcystis.
