Cloning and characterization of TaPP2AbB"-α, a member of the PP2A regulatory subunit in wheat.
Article in PloS one, 2014. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 10 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 phosphatase 2A (PP2A), a major Serine/Threonine protein phosphatase, consists of three subunits; a highly conserved structural subunit A, a catalytic subunit C, and a highly variable regulatory subunit B which determines the substrate specificity. Although the functional mechanism of PP2A in signaling transduction in Arabidopsis is known, their physiological roles in wheat remain to be characterized. In this study, we identified a novel regulatory subunit B, TaPP2AbB"-α, in wheat (Triticum aestivum L.). Subcellular localization indicated that TaPP2AbB"-α is located in the cell membrane, cytoplasm and nucleus. It interacts with both TaPP2Aa and TaPP2Ac. Expression pattern analyses revealed that TaPP2AbB"-α is strongly expressed in roots, and responds to NaCl, polyethylene glycol (PEG), cold and abscisic acid (ABA) stresses at the transcription level. Transgenic Arabidopsis plants overexpressing TaPP2AbB"-α developed more lateral roots, especially when treated with mannitol or NaCl. These results suggest that TaPP2AbB"-α, in conjunction with the other two PP2A subunits, is involved in multi-stress response, and positively regulates lateral root development under osmotic stress.
