Proteomic analysis of the regulatory network of salt stress in Chrysanthemum.
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 2 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
backgroundSaline-alkali stress is one of the main abiotic stresses that constrains plant growth. Understanding the response mechanism of ornamental plants to saline-alkali stress is of great significance for improving saline-alkali landscape greening. Chrysanthemum is a good ornamental plant with strong resistance to stress, rich colors and easy management.
resultsUsing TMT quantitative proteomics technology, leave and root of Chrysanthemum that were either untreated or treated with 200 mM NaCl for 12 h, screened the differentially expressed proteins. The results showed that 66 and 452 differential proteins were present in leaves and roots after salt treatment, respectively. GO function is mainly related to carbohydrate and energy metabolism, hormone response, antioxidant response and membrane protein activity. The KEGG metabolic pathway is mainly concentrated in glycine metabolism, glutathione metabolic pathway, carbon fixation in prokaryotes, 2-oxy-carboxylic acid metabolism. Combining transcripto-proteomics, GO and KEGG analyses revealed significant enrichment in starch anabolic catabolism, redox processes, ion homeostatic transport, phenylpropane biosynthesis.
conclusionsUnder salt stress, the active pathways of carbohydrate and energy metabolism and glutathione metabolism enable plants to accumulate more energy substances and improve antioxidant capacity, which may play a safeguarding role in maintaining growth and development and mitigating reactive oxygen species damage in Chrysanthemum under stress. The purpose of this study was to screen key proteins and regulatory networks through proteomic assay, and reveal the molecular mechanism of response to salt stress. The research not only provides resources for salt-tolerant breeding of Chrysanthemum but also offers theoretical support for agricultural production and ecological environmental protection.
