Despite a wealth of information on the accumulation of MPs in aquatic species, there is no information on the uptake and accumulation of MPs by higher plants. Terrestrial edible plants are directly exposed to MPs when agricultural soil was applied with organic manure, sewage sludge as fertilizer or plastic mulching. In this paper, the uptake of two sizes of polystyrene (PS) microbeads (0.2 and 1.0 mum) and then their distribution and migration in an edible plant lettuce were firstly investigated based on laboratory experiments. We used fluorescent markers to track PS microbeads in plant tissues and found fluorescence to be a sensitive and reliable detection method. Sections from untreated control lettuce showed no autofluorescence. When roots were treated with fluorescently labeled PS microbeads, the microbeads could be identified by its fluorescence. Our main study investigated the uptake of 0.2 mum beads, as few luminescence signals were observed in lettuce roots for 1.0 mum beads in our experiment. We observed that 0.2 mum fluorescent microbeads were extracellularly trapped in the root cap mucilage (which is a highly hydrated polysaccharide) and a dark green tip (which was typical of lettuce roots exposed to label PS beads) was usually visible to the naked eye. Confocal images revealed that the PS luminescence signals were mainly located in the vascular system and on the cell walls of the cortex tissue of the roots, indicated that the beads passed through the intercellular space via the apoplastic transport system. Once inside the central cylinder, the 0.2 mum PS beads were transferred from the roots to the stems and leaves via the vascular system following the transpiration stream. We also observed that the PS beads adhered to one another and self-assembled systematically into grape-like and (chain) string-like clusters in the intercellular space of the root and stem vascular tissue of lettuce plant. In contrast to the root and stem, PS beads were dispersed in the leaf tissue. Here, for the first time we provide evidence of the adherence, uptake, accumulation, and translocation of submicrometer MPs within an edible plant. Our findings highlight the previously underappreciated human exposure pathway to MPs through the consumption of contaminated crops and emphasize the need for new management strategies to control the release of MPs waste products into the terrestrial environment. Ultimately, the potential impacts of low range sized MPs on food safety of crop plants and human health need to be urgently considered.   Manganese Toxicity Inhibited Root Growth by Disrupting Auxin Biosynthesis and Transport in Arabidopsis 期刊论文  OAI收割 frontiers in plant science, 2017, 卷号: 8, 页码: 1-8 作者:  Zhao, Jingjing;  Wang, Wenying;  Zhou, Huakun;  Wang, Ruling;  Zhang, Ping 收藏  |  浏览/下载：82/0  |  提交时间：2017/06/22 manganese (Mn) toxicity  auxin accumulation  auxin efflux carriers  primary root growth  Arabidopsis   Manganese Toxicity Inhibited Root Growth by Disrupting Auxin Biosynthesis and Transport in Arabidopsis 期刊论文  OAI收割 FRONTIERS IN PLANT SCIENCE, 2017, 卷号: 8, 期号: x, 页码: 1-8 作者:  Xu, Jin 收藏  |  浏览/下载：23/0  |  提交时间：2017/04/11 manganese (Mn) toxicity  auxin accumulation  auxin efflux carriers  primary root growth  Arabidopsis   Lanthanum Inhibits Primary Root Growth by Repressing Auxin Carrier Abundances in Arabidopsis 期刊论文  OAI收割 FRONTIERS IN PLANT SCIENCE, 2017, 卷号: 8, 期号: x, 页码: - 作者:  Liu, Yangyang;  Sun, Liangliang;  Zhang, Ping;  Wan, Jinpeng;  Wang, Ruling   |  收藏  |  浏览/下载：36/0  |  提交时间：2017/10/26 Lanthanum  Auxin Accumulation  Auxin Carriers  Pinformed Protein  Primary Root Growth   Saline soil desalination by honeysuckle (Lonicera japonica Thunb.) depends on salt resistance mechanismKun 期刊论文  OAI收割 ECOLOGICAL ENGINEERING, 2016, 卷号: 88, 页码: 226-231 作者:  Yan, K;  Xu, HL;  Zhao, SJ;  Shan, JJ;  Chen, XB 收藏  |  浏览/下载：233/0  |  提交时间：2016/05/24 Phytoremediation  Root Na+ extrusion  Root respiration  Shoot Na+ accumulation   The Nitrification Inhibitor Methyl 3-(4-Hydroxyphenyl)Propionate Modulates Root Development by Interfering with Auxin Signaling via the NO/ROS Pathway 期刊论文  OAI收割 PLANT PHYSIOLOGY, 2016, 卷号: 171, 期号: 3, 页码: 1686-1703 作者:  Xu, Jin 收藏  |  浏览/下载：44/0  |  提交时间：2016/09/23 STEM-CELL NICHE  NITRIC-OXIDE PLAYS  ARABIDOPSIS ROOT  MERISTEM SIZE  TRANSCRIPTIONAL REGULATION  AUX/IAA PROTEINS  OXIDATIVE STRESS  SOLANUM-NIGRUM  GROWTH  ACCUMULATION   Red mud (RM)-Induced enhancement of iron plaque formation reduces arsenic and metal accumulation in two wetland plant species SCI/SSCI论文  OAI收割 2016 作者:  Yang J.
