Cell-to-cell movement of green fluorescent protein reveals post-phloem transport in the outer integument and identifies symplastic domains in Arabidopsis seeds and embryos.
Article in Plant physiology, 2005. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 127 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
Developing Arabidopsis (Arabidopsis thaliana) seeds and embryos represent a complex set of cell layers and tissues that mediate the transport and partitioning of carbohydrates, amino acids, hormones, and signaling molecules from the terminal end of the funicular phloem to and between these seed tissues and eventually to the growing embryo. This article provides a detailed analysis of the symplastic domains and the cell-to-cell connectivity from the end of the funiculus to the embryo, and within the embryo during its maturation. The cell-to-cell movement of the green fluorescent protein or of mobile and nonmobile green fluorescent protein fusions was monitored in seeds and embryos of plants expressing the corresponding cDNAs under the control of various promoters (SUC2, SUC3, TT12, and GL2) shown to be active in defined seed or embryo cell layers (SUC3, TT12, and GL2) or only outside the developing Arabidopsis seed (AtSUC2). Cell-to-cell movement was also analyzed with the low-molecular-weight fluorescent dye 8-hydroxypyrene-1,3,6-trisulfonate. The analyses presented identify a phloem-unloading domain at the end of the funicular phloem, characterize the entire outer integument as a symplastic extension of the phloem, and describe the inner integument and the globular stage embryo plus the suspensor as symplastic domains. The results also show that, at the time of hypophysis specification, the symplastic connectivity between suspensor and embryo is reduced or interrupted and that the embryo develops from a single symplast (globular and heart stage) to a mature embryo with new symplastic domains.
