Mastoparan-Induced Intracellular Ca2+ Fluxes May Regulate Cell-to-Cell Communication in Plants.
Article in Plant physiology, 1996. 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 relationship of Ca2+ and plasmodesmatal closure was examined in staminal hairs of Setcreasea purpurea by microinjecting cells with active mastoparan (Mas-7), inactive mastoparan (Mas-17), active inositol-1,4,5-trisphosphate (IP3), or inactive IP3. Calcium green dextran 10,000 was used to study cellular free Ca2+, and carboxyfluorescein was used to monitor plasmodesmatal closure. When Mas-7 was microinjected into the cytoplasm of cell 1 (the tip cell of a chain of cells), a rapid increase in calcium green dextran-10,000 fluorescence was observed in the cytoplasmic areas on both sides of the plasmodesmata connecting cells 1 and 2 during the same time that the diffusion of carboxyfluorescein through them was blocked. The inhibition of cell-to-cell diffusion was transient, and the closed plasmodesmata reopened within 30 s. The elevated Ca2+ level near plasmodesmata was also transient and returned to base level in about 1.5 min. The transient increase in Ca2+, once initiated in cell 1, repeated with an oscillatory period of 3 min. Elevated Ca2+ and oscillations of Ca2+ were also observed near interconnecting cell walls throughout the chain of cells, indicating that the signal had been transmitted. Previously, we reported that IP3 closed plasmodesmata; now we report that it stimulated Ca2+ and oscillations similar to Mas-7. The effect was specific for similar concentrations of Mas-7 over Mas-17 and active IP3 over inactive IP3. It is important that the Ca2+ channel blocker La3+ eliminated the responses from Mas-7 and IP3, indicating that an influx of Ca2+ was required. These results support the contention that plasmodesmata functioning is regulated via Ca2+ and that IP3 may be an intermediary between the stimulus and Ca2+ elevations.
