Roles of a putative mechanosensitive plasma membrane Ca2+-permeable channel OsMCA1 in generation of reactive oxygen species and hypo-osmotic signaling in rice.
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 5 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
Mechanosensing and its downstream responses are speculated to involve sensory complexes containing Ca(2+)-permeable mechanosensitive channels. On recognizing hypo-osmotic stress, plant cells initiate activation of a widespread signal transduction network involving second messengers such as Ca(2+) to trigger inducible defense responses including the induction of transcriptional factors. However, most of the components involved in these signaling networks still remain to be identified. Recently we identified and investigated OsMCA1, the sole homolog of the MCA family putative Ca(2+)-permeable mechanosensitive channels in rice. Functional characterization of the OsMCA1-suppressed cells as well as the overexpressing cells indicated that OsMCA1 is involved in the regulation of plasma membrane Ca(2+) influx and NADPH oxidase-mediated generation of reactive oxygen species (ROS) induced by hypo-osmotic stress. Here we will discuss possible molecular mechanisms and physiological functions of the MCA protein in hypo-osmotic signaling.
