In vivo role of Arabidopsis arginase in arginine metabolism and abiotic stress response.
Article in Plant signaling & behavior, 2013. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 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
Nitric oxide (NO) and polyamines play essential roles in many developmental processes and abiotic stress responses in plants. NO and polyamines are metabolized from arginine through NO synthase (NOS) and arginine decarboxylase (ADC), respectively. Function of arginase, another important enzyme involved in arginine metabolism, in abiotic stress remains largely unknown. In the recent study, we have dissected the impact of arginase on arginine metabolism and abiotic stress responses through manipulating AtARGAHs expression. The results suggested that manipulation of arginase expression modulated accumulation of arginine and direct downstream products of arginine catabolism. AtARGAHs knockout lines exhibited increased accumulation of polyamines and NO and enhanced abiotic stress tolerance, while AtARGAHs overexpressing lines displayed the opposite results. Notably, we highlighted that Arabidopsis arginase plays distinctive and dual roles in the crosstalk between polyamines and NO signaling during abiotic stress responses, mediating both arginine metabolism and reactive oxygen species (ROS) accumulation. It is likely that accumulation of both NO and polyamines might activate abiotic stress responses in the plant.
