Metabolomics combined with proteomics reveals phytotoxic effects of norfloxacin under drought stress on Oryza sativa
In recent decades, plants enduring abiotic stresses such as drought and chemical stresses. Currently, the mechanism of combined antibiotic and drought stress response and its impact on crop growth and food security remains poorly understood. Here, the mechanism of stress responses under the exposure of norfloxacin (NF) and drought (D) individually and in combination (DNF) were explored on rice (Oryza sativa) cultivar Hanyou73 through proteomics and metabolomic analysis. All treatments adversely affected chlorophyll fluorescence kinetics, antioxidant enzyme activities, rice grain composition and yield. The results showed that in DNF the antibiotic was accumulated 627% more than NF treatment in rice grains while in leaves there was no significant difference under both treatments. The proteomic revealed that differentially expressed identified proteins were involved in carbohydrate metabolism, amino acid metabolism, photosynthesis and mRNA binding. However, the metabolomics results showed that the abundance of metabolites related to RNA biosynthesis and amino acid metabolism were more affected. The disruptions caused in rice plant under DNF treatment become more severe, this makes it more susceptible than individual D and NF treatment. These findings improve our knowledge about the response of rice plant to cope with antibiotic contamination alone and in combination with drought.
期刊介绍:
Plant Physiology and Biochemistry publishes original theoretical, experimental and technical contributions in the various fields of plant physiology (biochemistry, physiology, structure, genetics, plant-microbe interactions, etc.) at diverse levels of integration (molecular, subcellular, cellular, organ, whole plant, environmental). Opinions expressed in the journal are the sole responsibility of the authors and publication does not imply the editors'' agreement.
Manuscripts describing molecular-genetic and/or gene expression data that are not integrated with biochemical analysis and/or actual measurements of plant physiological processes are not suitable for PPB. Also "Omics" studies (transcriptomics, proteomics, metabolomics, etc.) reporting descriptive analysis without an element of functional validation assays, will not be considered. Similarly, applied agronomic or phytochemical studies that generate no new, fundamental insights in plant physiological and/or biochemical processes are not suitable for publication in PPB.
Plant Physiology and Biochemistry publishes several types of articles: Reviews, Papers and Short Papers. Articles for Reviews are either invited by the editor or proposed by the authors for the editor''s prior agreement. Reviews should not exceed 40 typewritten pages and Short Papers no more than approximately 8 typewritten pages. The fundamental character of Plant Physiology and Biochemistry remains that of a journal for original results.
