Effects of cell wall synthesis on cell polarity in the red alga Porphyra yezoensis.
Article in Plant signaling & behavior, 2008. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
Polarity is a fundamental cell property essential for differentiation, proliferation and morphogenesis in unicellular and multicellular organisms. We have recently demonstrated that phosphatidylinositol 3-kinase (PI3K) activity is required for the establishment of anterior-posterior axis, leading to asymmetrical localization of F-actin in migrating monospores of the red alga Porphyra yezoensis. We also showed that the formation of the apical-basal axis via adhesion of monospores to the substratum after the cessation of migration requires newly synthesized proteins and does not depend on PI3K activity. However, little is known about the mechanism and regulation of axis conversion during development of monospores. In this addendum, we report our investigation as to the role of the cell wall in axis conversion. Our results indicate that inhibition of cell wall synthesis prevented the development of germlings. Also, defects in the cell wall disrupted the asymmetrical distribution of F-actin and inhibited the adhesion to the substratum that is required for establishment of apical-basal axis. Hence, we conclude that the cell wall is critical for the maintenance of cell polarity in migrating cells, which is indirectly involved in axis conversion via enabling monospores to adhere to the substratum.
