入侵植物  互花米草  资源化利用  秸秆资源  药用价值  耐盐基因  Invasive plant  Spartina alterniflora  Resource utilization  Straw resource  Medicinal value  Salt tolerant gene  In China, Spartina alterniflora, an invasive alien plant species, covers an area of approximately 54 600 hectares. The total dry matter of the aboveground part of S. alterniflora is 7.5*10~5~1.15*10~6 tons per year. The control and utilization of S. alterniflora have received increasing attention. A combined utilization and control approach could produce simultaneous economic and ecological benefits. Studies of the utilization of S. alterniflora in China tended to focus on the direct utilization of straw, including its use as fuel, feed, and raw material. These methods of utilization were generally low-value. Possible high-value utilization includes the medicinal value of S. alterniflora and its salt-tolerant genes. In all the studies, the largest proportion (43%) of straw was utilized as fuel, whereas the smallest proportion (approximately 8%) was utilized for other purposes, such as fertilizer and for its salt-tolerant genes. Previous studies have focused on utilization technologies, but they have not looked at S. alterniflora collection technology and market promotion. In the future, attention should be paid to every link of the industry chain of S. alterniflora utilization, and cooperation between research institutions and enterprises is essential for the synchronous development of industry, education, and research.

微塑料  生菜  聚苯乙烯微球  吸收  积累  健康风险  microplastics  lettuce  polystyrene microbeads  uptake  accumulation  human health risk  Microplastic (MP, 100 nm-5 mm) may present an attributable risk to ecosystem and human health, and its pollution has become a global environmental concern. 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.
