Alterations in Arginase Activity and Polyamine Metabolism Contribute to the Mode of Action of Canavanine in Tomato Roots.

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
Canavanine (CAN) is a nonproteinogenic amino acid, synthesised by many legumes (e.g., alfalfa, hairy vetch) and acts as a strong inhibitor of root growth. Thus, CAN may be considered as an allelopathic compound, influencing natural and agroecosystems. CAN is a structural analogue of arginine (Arg), so its toxicity results from its primary mode of action due to interference with Arg-dependent processes, especially incorporation into proteins instead of Arg. The aim of the work was to investigate the impact of CAN (10, 50 µM) treatment (24 or 72 h) on Arg catabolism and content of polyamines (PAs) in the roots of tomato (
