Coordination mechanism of cell and cyanelle division in the glaucophyte alga Cyanophora sudae.

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 unicellular algae with a single chloroplast, two mechanisms coordinate cell and chloroplast division: the S phase-specific expression of chloroplast division genes and the permission of cell cycle progression from prophase to metaphase by the onset of chloroplast division. This study investigated whether a similar mechanism exists in a unicellular alga with multiple chloroplasts using the glaucophyte alga Cyanophora sudae, which contains four chloroplasts (cyanelles). Cells with eight cyanelles appeared after the S phase arrest with a topoisomerase inhibitor camptothecin, suggesting that the mechanism of S phase-specific expression of cyanelle division genes was conserved in this alga. Inhibition of peptidoglycan synthesis by β-lactam antibiotic ampicillin arrested cells in the S-G2 phase, and inhibition of septum invagination with cephalexin resulted in cells with two nuclei and one cyanelle, despite inhibition of cyanelle division. This indicates that even in the unicellular alga with four chloroplasts, the cell cycle progresses to the M phase following the progression of chloroplast division to a certain division stage. These results suggested that C. sudae has two mechanisms for coordinating cell and cyanelle division, similar to the unicellular algae with a single chloroplast.
