Dynamic changes in the frequency and architecture of plasmodesmata during the sink-source transition in tobacco leaves.

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 sink-source transition in tobacco leaves was studied noninvasively using transgenic plants expressing the green-fluorescent protein (GFP) under control of the Arabidopsis thaliana SUC2 promoter, and also by imaging transgenic plants that constitutively expressed a tobacco mosaic virus movement protein (MP) fused to GFP (MP-GFP). The sink-source transition was measured on intact leaves and progressed basipetally at rates of up to 600 microns/h. The transition was most rapid on the largest sink leaves. However, leaf size was a poor indicator of the current position of the sink-source transition. A quantitative study of plasmodesmatal frequencies revealed the loss of enormous numbers of simple plasmodemata during the sink-source transition. In contrast, branched plasmodesmata increased in frequency during the sink-source transition, particularly between periclinal cell walls of the spongy mesophyll. The progression of plasmodesmal branching, as mapped by the labelling of plasmodesmata with MP-GFP fusion, occurred asynchronously in different cell layers, commencing in trichomes and appearing lastly in periclinal cell walls of the palisade layer. It appears that dividing cells retain simple plasmodesmata for longer periods than nondividing cells. The rapid conversion of simple to branched plasmodesmata is discussed in relation to the capacity for macromolecular trafficking in developing leaf tissues.
