Temporal responses of wild-type pigmentation and RcaE-deficient strains of Fremyella diplosiphon during light transitions.
Article in Communicative & integrative biology, 2011. 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
A temporal study was conducted to evaluate the dynamic complementary chromatic adaptation (CCA) response of two Fremyella diplosiphon strains-wild-type pigmentation strain SF33 and an RcaE-deficient (ΔrcaE) strain, which lacks the photosensor that regulates CCA. SF33 and ΔrcaE cultures were monitored for 15 days after transition of green-light (GL) acclimated cultures to red light (RL) and vice versa. SF33 showed similar growth irrespective of the external light quality; however, a ΔrcaE strain grew slower than SF33 under both RL and GL. Chlorophyll a (chla) content increased in both strains over time and was not much different under RL and GL indicating that chla biosynthesis is not affected significantly by light quality or RcaE function. Phycoerythrin is the sole pigment to absorb GL, whereas several pigments, i.e., allophycocyanin, phycocyanin and chla, function under RL to drive photosynthesis. SF33 compensates for this by synthesizing a higher percentage of PE under GL. The final pigment distribution in the ΔrcaE mutant was found to be more different from SF33 under GL than under RL indicating that RcaE is needed for a transitional response to RL and RL-dependent repression of PE accumulation, yet RcaE is virtually critical for both transitioning to and a full adaptation to GL.
