A loss-of-function mutation in Calmodulin2 gene affects pollen germination in Arabidopsis thaliana.
Article in Plant molecular biology, 2010. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 21 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
Calmodulin (CAM) is an ubiquitous calcium binding protein whose function is to translate the signals, perceived as calcium concentration variations, into the appropriate cellular responses. In Arabidopsis thaliana there are 4 CAM isoforms which are highly similar, encoded by 7 genes, and one possible explanation proposed for the evolutionary conservation of the CAM gene family is that the different genes have acquired different functions so that they play possibly overlapping but non-identical roles. Here we report the characterization of the Arabidopsis mutant cam2-2, identified among the lines of the gene-trapping collection EXOTIC because of a distorted segregation of kanamycin resistance. Phenotypic analysis showed that in normal growth conditions cam2-2 plants were indistinguishable from the wild type while genetic analysis showed a reduced transmission of the cam2-2 allele through the male gametophyte and in vitro pollen germination revealed a reduced level of germination in comparison with the wild type. These results provide genetic evidence of the involvement of a CAM gene in pollen germination and support the theory of functional diversification of the CAM gene family.
