Acclimation to low or limiting CO2 in non-synchronous Chlamydomonas causes a transient synchronization of the cell division cycle.
Article in Photosynthesis research, 2011. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
Acclimation of Chlamydomonas reinhardtii (hereafter, Chlamydomonas) to low or limiting CO(2) or inorganic carbon (C(i)) has been studied fairly extensively with regard to the mechanisms underlying the inducible C(i) acquisition systems and the signal transduction pathway involved in recognizing and responding to decreased C(i) availability. Investigation of low C(i )acclimation responses typically is performed with non-synchronous cultures grown in continuous light to avoid any effects of the cell division cycle (CDC) confounding interpretation of acclimation responses. However, little is known about whether acclimation to low C(i) might affect the distribution of cells among the various stages of the CDC. To investigate the effects of a limiting-C(i) challenge on the CDC of Chlamydomonas, flow cytometry was used to monitor the distribution of cells among the CDC stages in both synchronous and non-synchronous cultures during acclimation to low or limiting C(i). When faced with C(i) limitation, non-synchronous cultures of Chlamydomonas undergo transient synchronization as those cells past the Commitment point of the CDC undergo division, while the remainder of the cells pause their growth in early G-phase, with the result that the cells all accumulate in early G-phase, appearing transiently synchronized until acclimated sufficiently to the decreased C(i) for growth to resume. This perturbation of the CDC by a limiting-C(i) challenge has important implications for the interpretation of gene expression and other responses apparently induced by low or limiting C(i).
