Glycine uptake into barley mesophyll vacuoles is regulated but not energized by ATP.
Article in Plant physiology, 1992. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
[U-(14)C]glycine uptake into barley (Hordeum vulgare cv Hasso) vacuoles was investigated. Glycine (2 millimolar) transport was stimulated two- to fourfold by NaATP. Stimulation was saturable with respect to ATP (1 millimolar) and linear up to 20 millimolar glycine. Stimulation by NaATP was suppressed by Mg(2+) in equimolar amounts. Neither MgATP nor Mg-inorganic pyrophosphate had any effect on basal transport rate. Thus, the proton motive force can be excluded as the driving force. Uncouplers (valinomycine/carbonylcyanide-m-chlorophenylhydrazone) inhibited the basal rate up to 30% but had no influence on NaATP-stimulated uptake. Vanadate had no effect on either basal or NaATP-stimulated uptake. Nonhydrolyzable ATP analogs (adenylyl(beta, gamma-methylen)-diphosphate or adenylyl-imidodiphosphate) stimulated comparable to NaATP. Other nucleotides (UTP, ADP) had no effect. Some evidence exists that other amino acids (arginine, alanine, isoleucine, phenylalanine) are transported to a certain extent by a similar mechanism. The results indicate a high capacity channel-like translocator that is regulated but not energized by ATP.
