| 英文摘要 | The phytotoxicities of TBECH diastereomers to plants at the biochemical and molecular levels were investigated in a hydroponic study by using maize as a model plant. The results showed that TBECH could induce the production of two species of reactive oxygen species (ROS), O-2(center dot-) and H2O2, in maize tissues. The accumulation of ROS was the highest when maize was exposed to beta-TBECH. TBECH enhanced the phosphorylation of plant histone, and the contents of gamma-H2AX in maize followed the order beta-TBECH > alpha beta-TBECH > gamma delta-TBECH > gamma-TBECH. Transcriptome profiling revealed that antioxidant enzyme genes (AEGs) were over-expressed in maize when stressed by technical grade TBECH. The RT-PCR detection further validated that three typical AEGs, including CAT, SOD, and POD genes, were time-dependent and selectively expressed under the influence of TBECH diastereomers. Molecular compositions of maize root exudates characterized by FT-ICR-MS were significantly different among the four groups of TBECH diastereomer treatments. TBECH diastereomers specifically affected the chemical diversity and abundance of root exudates. New insights into the biochemical effects of TBECH on plants are provided in this work, which is helpful to deepening the understanding of their stereo-selectivity. (C) 2020 Elsevier B.V.
