1 · What the graph read from it

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.

2 · The registry

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

Cytokinins are adenine derivatives serving as phytohormones, which are essential regulators of plant growth, development, and response to environmental factors. The transport process of cytokinins determines their spatial distributions and is critical to their functions. The AZA-GUANINE RESISTANT (AZG) family member AZG2 in Arabidopsis thaliana has been identified as a cytokinin and purine transporter. Here, we characterize the binding and transport of AZG2 towards the natural cytokinin, trans-zeatin (tZ), as well as adenine. AZG2 structures are determined in both the substrate-unbound, adenine-bound, and tZ-bound states, under both acidic and neutral pH. Key residues involved in substrate binding are identified. Two distinct conformations are observed in the tZ-bound state of AZG2 in the neutral pH. Structural analysis reveals the structural dynamics of AZG2 during cytokinin transport, which fit into the elevator-type transport model. These results provide insights into the molecular mechanism of cytokinin transport in plants.
