Integrated physiological and proteomic analysis of embryo and endosperm reveals central salt stress response proteins during seed germination of winter wheat cultivar Zhengmai 366.
Article in BMC plant biology, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It has been retracted, and should not be counted. Cited by 3 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
backgroundSalinity is a major abiotic stressor that affects seed germination, plant growth, and crop production. Seed germination represents the beginning of plant growth and is closely linked with subsequent crop development and ultimate yield formation. This study attempted to extend findings regarding the potential proteomic dynamics during wheat seed germination under salt stress and to explore the mechanism of crop salt response.
resultsSalt stress significantly affected seed physiological activities during the germination process, resulting in significant decreases in phytohormone and α-amylase activity and significant increases in soluble sugar, starch, and ADP glucose pyrophosphorylase activity. A comparative proteomics approach was applied to analyze the dynamic proteome changes of embryo and endosperm during seed germination in Chinese winter wheat cultivar Zhengmai 366 under salt stress. Two-dimensional electrophoresis identified 92 and 61 differentially accumulated proteins (DAPs) in response to salt stress in embryo and endosperm, respectively. Both organs contained a high proportion of DAPs involved in stress defense, energy metabolism, and protein/amino acid metabolism. The endosperm had more DAPs related to storage proteins and starch metabolism than the embryo, and 2% of DAPs participating in lipid and sterol metabolism were specifically detected in the embryo.
conclusionsSeed physiological activities were significantly affected during the germination process when subjected to salt stress. The DAPs involved in stress defense and energy metabolism were upregulated whereas those related to reserve substance degradation and protein/amino acid metabolism were significantly downregulated, leading to delayed seed germination under salt stress. Our proteomic results revealed synergistic regulation of the response to salt stress during seed germination.
