A New Type of Light-Harvesting Complex Detected when Growing Rhodopseudomonas palustris under Low Light Intensity Conditions.

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
The predominance of the maximum at 800 nm for the light-harvesting complex LH4 (B800) and at 850 nm for LH2 (B800-850) from Rps. palustris is determined by the composition of αβ-polypeptides and pigments. In low light (LL) for Rps. palustris, strain KM 286 (1e5), along with LH4, the LL LH2 complex was synthesized with the same absorption at 800 and 850 nm. It differed from the LH4 and LH2 complex, which is synthesized under high illumination, in the composition and content of carotenoids (Car) and bacteriochlorophyll a (BChl a). LH4 differed from LL LH2 and LH2 by an additional emission maximum at 766 nm in the BChl a fluorescence spectra. All three complexes had approximately the same level (about 45%) of the energy transfer efficiency from Car to BChl a. Isolation of LL LH2 complex from Rps. palustris confirms the hypothesis of the synthesis in these bacteria under low light conditions of other types of complexes, except LH4, which is due to the multiple biosynthesis genes of αβ-polypeptides and the possibility of their various combinations.
