| 英文摘要 | The interaction between arsenic (As) and phenanthrene (PHE) in Pteris vittata L. was investigated in this study. The migration and occurrence of PHE in P. vittata were determined by two-photon laser scanning confocal microscopy. Data indicated that PHE supplementation lowers the As concentration in P. vittata, decreasing As levels by 16.8-39.9% in the pinnae, 30.0-49.0% in the rachis, and 45-51.5% in the roots, respectively. Different arsenic species inhibited P. vittata PHE absorption. The most significant effect was observed using dimethylarsenic acid (DMA), which decreased PHE accumulation by 20.73%. With the exception of elevated As(V) concentrations in As(III)-treated plants, PHE treatment significantly reduced inorganic As concentrations in P. vittata. However, PHE elevated root DMA concentrations by 9%. According to in situ visualization, PHE is primarily found in the upper and lower epidermis and stomatal cells, particularly the stomata guard cells. (C) 2016 Elsevier Ltd. All rights reserved. |
