Evaluation of the molecular mechanism underlying proline metabolic and catabolic pathways and some morpho-physiological traits of tobacco (Nicotiana tabacum L.) plants under arsenic stress.
Article in BMC plant biology, 2025. 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
backgroundIn recent decades, arsenic (As) toxicity has emerged as a significant challenge in many countries. It not only reduces the growth and performance of plants, but also poses a threat to human health. The synthesis of compatible solutes, particularly proline, is a mechanism plants utilize to cope with stress. Investigating the metabolic pathways of proline would deepen our understanding for future molecular breeding or genetic engineering efforts. Therefore, the aim of this study was to explore the metabolic and catabolic pathways of proline, as well as the morpho-physiological traits of tobacco, under As stress.
resultsThe results revealed a significant decrease in morphological traits and photosynthetic efficiency, chlorophyll content, and total soluble protein content with increasing As concentration. The results also showed that proline content, total soluble carbohydrates, hydrogen peroxide, and malondialdehyde, as well as the activity of two antioxidant enzymes, superoxide dismutase and ascorbate peroxidase, increased with increasing As concentration.

conclusionThe results showed that the accumulation of proline at the lowest (10 mg As Kg
