Pea DNA helicase 45 promotes salinity stress tolerance in IR64 rice with improved yield.
Article in Plant signaling & behavior, 2012. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 18 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
The helicases provide duplex unwinding function in an ATP-dependent manner and thereby play important role in almost all the nucleic acids transaction. Since stress reduces the protein synthesis by affecting the cellular gene expression machinery, so it is evident that molecules involved in nucleic acid processing including translation factors/helicases are likely to be affected. Earlier pea DNA helicase 45 (PDH45), a homolog of translation initiation factor 4A (eIF4A) was reported to play important role in salinity stress tolerance in tobacco and Bangladeshi rice variety Binnatoa. We report here the overexpression of PDH45 gene in the indica rice variety IR64, via Agrobacterium-mediated transformation. Molecular analysis of the transgenics revealed stable integration of the transgene in the T1 generation. Enhanced tolerance to salinity was observed in the plants transformed with PDH45 gene. Better physiological and yield performances including endogenous nutrient contents (N, P, K, Na) of the transgenics under salt treatment were observed as compared with wild type (WT), vector control and antisense transgenics. All these results indicated that the overexpression of PDH45 in the IR64 rice transgenics enable them to perform better with enhanced salinity stress tolerance and improved physiological traits. Based on the homology of PDH45 protein with eIF4A protein we suggest that it may act at the translational level to enhance or stabilize protein synthesis under stress conditions.
