Properties of enhanced tonoplast zinc transport in naturally selected zinc-tolerant silene vulgaris
Article in Plant physiology, 1999. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 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
It was demonstrated recently that isolated tonoplast vesicles derived from plants of a Zn-tolerant ecotype of Silene vulgaris accumulate more Zn than vesicles derived from a Zn-sensitive ecotype. We have now characterized the tonoplast-transport system that causes this uptake difference and demonstrated its genetic correlation to Zn tolerance using plant crosses. We conclude that the tonoplast Zn uptake system of the tolerant ecotype differs greatly in its characteristics from that of the sensitive one, with the most prominent differences being its insensitivity to protonophores and ortho-vanadate and its stimulation by Mg-GTP. These differences in characteristics are most likely due to the fact that Zn can be taken up by two or more parallel pathways, which are not present in the same proportions in both ecotypes. In both ecotypes, Zn is actively transported across the tonoplast (temperature coefficient > 1.6), most likely as a free ion, since citrate does not accumulate in vesicles. Most importantly, the uptake difference found using the ecotypes was also found between homozygous Zn-tolerant and Zn-sensitive F3 plants, proving the genetic correlation between increased tonoplast Zn transport and naturally selected Zn tolerance in S. vulgaris.
