Abstract

Abstract Silver nanoparticles (AgNP) exhibit size and concentration dependent toxicity to terrestrial plants, especially crops. AgNP exposure could decrease seed germination, inhibit seedling growth, affect mass and length of roots and shoots. The phytotoxic pathway has been partly understood. Silver (as element, ion or AgNP) accumulates in roots/leaves and triggers the defense mechanism at cellular and tissue levels, which alters metabolism, antioxidant activities and related proteomic expression. Botanical changes (either increase or decrease) in response to AgNP exposure include reactive oxygen species generation, superoxide dismutase activities, H2O2 level, total chlorophyll, proline, carotenoid, ascorbate and glutathione contents, etc. Such processes lead to abnormal morphological changes, suppression of photosynthesis and/or transpiration, and other symptoms. Although neutral or beneficial effects are also reported depending on plant species, adverse effects dominate in majority of the studies. More in depth research is needed to confidently draw any conclusions and to guide legislation and regulations.
银纳米粒子对陆地植物种子萌发和生长的植物毒性作用
摘要银纳米粒子(AgNP)对陆地植物,尤其是作物具有大小和浓度依赖性毒性。AgNP暴露可降低种子发芽率,抑制幼苗生长,影响根和芽的质量和长度。植物毒性途径已被部分了解。银(作为元素、离子或AgNP)在根/叶中积累,并在细胞和组织水平上触发防御机制,从而改变代谢、抗氧化活性和相关蛋白质组表达。AgNP暴露引起的植物变化(增加或减少)包括活性氧生成、超氧化物歧化酶活性、H2O2水平、总叶绿素、脯氨酸、类胡萝卜素、抗坏血酸和谷胱甘肽含量等。这些过程会导致异常形态变化、光合作用和/或蒸腾作用抑制以及其他症状。尽管根据植物种类也有中性或有益影响的报道,但在大多数研究中,不良影响占主导地位。需要进行更深入的研究,以自信地得出任何结论,并指导立法和法规。
