Intracellular localization and physiological function of a rice Ca²⁺-permeable channel OsTPC1.
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 11 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
Two-pore channels (TPCs) are cation channels with a voltage-sensor domain conserved in plants and animals. Rice OsTPC1 is predominantly localized to the plasma membrane (PM), and assumed to play an important role as a Ca²⁺-permeable cation channel in the regulation of cytosolic Ca²⁺ rise and innate immune responses including hypersensitive cell death and phytoalexin biosynthesis in cultured rice cells triggered by a fungal elicitor, xylanase from Trichoderma viride. In contrast, Arabidopsis AtTPC1 is localized to the vacuolar membrane (VM). To gain further insights into the intracellular localization of OsTPC1, we stably expressed OsTPC1-GFP in tobacco BY-2 cells. Confocal imaging and membrane fractionation revealed that, unlike in rice cells, the majority of OsTPC1-GFP fusion protein was targeted to the VM in tobacco BY-2 cells. Intracellular localization and functions of the plant TPC family is discussed.
