摘要:
环境纳米材料在环境治理与农业生产等领域具有积极作用,但也给生态系统带来了不容忽视的潜在危害。丛枝菌根(Arbuscular mycorrhizal, AM)真菌可促进植物对营养元素的吸收并提高植物的抗逆性,也可降低环境纳米材料的毒性作用,探究AM真菌对环境纳米材料的响应和减毒效应已成为近来的研究热点。通过梳理相关研究进展发现,纳米材料会因材料自身性质、环境浓度和土壤性质等的差异而对土壤AM真菌群落结构、多样性及其生长与侵染产生不同影响,同时AM真菌也能通过固持纳米颗粒、改善根际环境和调节宿主植物营养与水分状况、降低纳米材料的吸收转运以及增强系统防御等途径来调控纳米材料的生物环境效应,缓解其进入环境后所带来的危害。最后结合现状,提出了未来AM真菌与纳米材料互作研究中应该关注的重点:一方面可通过借助新型手段探究AM真菌对纳米材料的响应机制并试图识别具有纳米材料高耐受性AM真菌,另一方面通过加强对复杂体系下纳米材料土壤环境行为和植物毒害效应的研究以最大限度地发挥AM真菌的调控作用,旨在为环境纳米材料的科学应用和安全管控提供理论依据。
Abstract:
Environmental nanomaterials (NMs) have positive effects in fields such as environmental governance and agricultural production , but also bring potential hazards that cannot be ignored in the ecosystem. Arbuscular mycorrhizal (AM) fungi can promote plant nutrient absorption, improve plant resistance to stress, and also reduce the toxicity of environmental NMs. Recently, it has become a hot topic to explore the response and toxicity attenuation role of AM fungi to environmental NMs. Based on a search and review of the relevant literature s, environmental NMs have differential effects on the community structure , diversity, growth and colonization of soil AM fungi due to differences in material properties, environmental concentrations, soil properties , and so on. Meanwhile, AM fungi can regulate the bio-environmental effects of NMs by fixing nanoparticles, improving the rhizosphere environment, regulating the nutritional and water status es of host plants, reducing the absorption and transport of NMs, and enhancing the defense of plant systems. These measures can lessen the hazards caused by NMs after entering the environment. Finally, based on the current status, the key points that should be paid attention to in future research on the interaction between AM fungi and NMs are proposed: revealing the response mechanism s of AM fungi to NMs through new methods and i dentifying species with high tolerance of NMs; strengthening the research on soil environmental behavior and plant toxicity of NMs under complex systems and maximizing the regulation function of AM fungi . These efforts may provide a theoretical basis for the scientific application and safety management of environmental NMs.
