Effect of overexpression of kinase- or RNase-deficient OsIRE1 on the endoplasmic reticulum stress response in transgenic rice plants.
Article in Plant signaling & behavior, 2013. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
IRE1 is an endoplasmic reticulum (ER) stress sensor protein in eukaryotes. In this study, we generated transgenic rice plants overexpressing three types of OsIRE1, including wild-type OsIRE1 (IRE1-OE) and two disrupted-IRE1s deficient in either kinase activity (K519A-OE) or RNase activity (K833A-OE), under the control of a constitutive promoter. Overexpression of wild-type IRE1 induced the ER stress response in transgenic rice even under non-stress conditions, whereas K519A-OE and K833A-OE had dominant negative effects on endogenous OsIRE1 expression in these transgenic plants. These lines exhibited phenotypes that were quite similar to those of OsIRE1 knock-down rice. These observations suggest that the two types of functionally disrupted OsIRE1 proteins behave as competitive inhibitors toward the ER stress response in transgenic rice plants. Furthermore, OsIRE1 may have a vital, as yet unidentified function, as determined through the characterization of the transgenic plants generated in this study.
