Activation of Plant Plasma Membrane Ca2+-Permeable Channels by Race-Specific Fungal Elicitors.
Article in Plant physiology, 1997. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 44 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 response of plant cells to invading pathogens is regulated by fluctuations in cytosolic Ca2+ levels that are mediated by Ca2+-permeable channels located at the plasma membrane of the host cell. The mechanisms by which fungal elicitors can induce Ca2+ uptake by the host cell were examined by the application of conventional patch-clamp techniques. Whole-cell and single-channel experiments on tomato (Lycopersicon esculentum L.) protoplasts revealed a race-specific fungal elicitor-induced activation of a plasma membrane Ca2+-permeable channel. The presence of the fungal elicitor resulted in a greater probability of channel opening. Guanosine 5[prime]-[[beta]-thio]diphosphate, a GDP analog that locks heterotrimeric G-proteins into their inactivated state, abolished the channel activation induced by the fungal elicitor, whereas guanosine 5[prime][[gamma]-thio]triphosphate, a nonhydrolyzable GTP analog that locks heterotrimeric G-proteins into their activated state, produced an effect similar to that observed with the fungal elicitor. Mastoparan, which stimulates GTPase activity, mimicked the effect of GTP[[gamma]]S. The addition of HA1004 (a protein kinase inhibitor) in the presence of the elicitor totally abolished channel activity, whereas okadaic acid (a protein phosphatase inhibitor) moderately enhanced channel activity, suggesting that the activation of the channel by fungal elicitors is modulated by a heterotrimeric G-protein-dependent phosphorylation of the channel protein.
