Functional characterisation of OsCPK21, a calcium-dependent protein kinase that confers salt tolerance in rice.
Article in Plant molecular biology, 2011. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 70 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
Calcium acts as a messenger in various signal transduction pathways in plants. Calcium-dependent protein kinases (CDPKs) play important roles in regulating downstream components in calcium signaling pathways. In rice, the CDPKs constitute a large multigene family consisting of 29 genes, but the biological functions and functional divergence or redundancy of most of these genes remain unclear. Using a mini-scale full-length cDNA overexpressor (FOX) gene hunting system, we generated 250 independent transgenic rice plants overexpressing individual rice CDPKs (CDPK FOX-rice lines). These CDPK FOX-rice lines were screened for salt stress tolerance. The survival rate of the OsCPK21-FOX plants was higher than that of wild-type (WT) plants grown under high salinity conditions. The inhibition of seedling growth by abscisic acid (ABA) treatment was greater in the OsCPK21-FOX plants than in WT plants. Several ABA- and high salinity-inducible genes were more highly expressed in the OsCPK21-FOX plants than in WT plants. These results suggest that OsCPK21 is involved in the positive regulation of the signaling pathways that are involved in the response to ABA and salt stress.
