Is there a link between protein kinase CK2 and auxin signaling?
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 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
Protein kinase CK2 is a pleitropic Ser/Thr kinase present in all eukaryotes. In order to study the effects of CK2 depletion on plant development, we have recently generated Arabidopsis transgenic plants expressing a CK2alpha-inactive mutant under the control of an inducible promoter. Our results showed that continuous expression of the transgene had a dominant negative effect and was lethal for Arabidopsis plants. Overexpression of the CK2alpha-inactive subunit provoked cell cycle arrest, by perturbation of both G(1)/S and G(2) cell cycle phases. The effects on cell division were particularly strong in root meristems, causing inhibition of lateral root formation even when the mutant protein was transiently induced. Processes that rely on cell expansion, such as hypocotyl elongation in dark-grown seedlings, were also strongly affected. We propose that CK2 regulates auxin-signaling pathways.
