Plasmodesma-mediated selective protein traffic between "symplasmically isolated" cells probed by a viral movement protein.
Article in The Plant cell, 2002. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 20 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
Intercellular communication is essential for differentiation and development. In plants, plasmodesmata (PD) form cytoplasmic channels for direct communication. During plant development, programmed reduction in PD number and transport capacity creates the so-called symplasmic domains. Small fluorescent dyes and ions can diffuse among cells within a domain but not across domain boundaries. Such symplasmic isolation is thought to allow groups of cells to differentiate and develop into tissues with distinct structures and functions. Whether or how "symplasmically isolated" cells communicate with one another is poorly understood. One well-documented symplasmic domain is the sieve element-companion cell (SE-CC) complex in the phloem tissue. We report here that, when produced in the CC of transgenic tobacco, the 3a movement protein (3a MP) of Cucumber mosaic virus fused to green fluorescent protein (GFP) can traffic out of the SE-CC complex via PD. The extent of 3a MP:GFP traffic across the boundary between vascular and nonvascular tissues depends on organ type and developmental stage. Our findings provide experimental evidence that endogenous machinery exists for protein traffic between the symplasmically isolated SE-CC complex and neighboring cells. We suggest that PD-mediated traffic of selected macromolecules can be a mechanism for symplasmically isolated cells to communicate with one another.
