| 英文摘要 | insecticide is always used to control the damage from pests, while the potential influence on plants is rarely known. time-course metabolic changes of wild and bacillus thuringiensis (bt) transgenic rice (oryza sativa l.) plants after insecticide treatment were investigated by using gas chromatography-mass spectrometry (gc-ms). a combined statistical strategy of 2-way anova and multivariate analyses (principal component analysis and hierarchal cluster analysis) was performed to find the stress-associated effects. the results reveal that a wide range of metabolites were dynamically varied in both varieties as a response to insecticide, in multiple metabolic pathways, such as biosynthesis and metabolism of amino acids, carbohydrates, fatty acids, tca cycle, and the shikimate/phenylpropanoid pathway, and most of the changes were correlated with the exposure time and dependent on the variety. a set of stress defenses were activated, including phytohormone signaling pathway, antioxidant defense system, shilcimate-mediated secondary metabolism, and so on. in particular, insecticide led to much stronger regulations of signaling molecules (salicylate and the precursor of jasmonate) and antioxidants (alpha-tocopherol and dehydroascorbate/ascorbate) in bt-transgenic variety at the early stage. our results demonstrated that the bt-transgenic rice had a more acute and drastic response to insecticide stress than its non-transgenic counterpart in antioxidant system and signaling regulation. |
