摘要

植物科学的最新进展大大加强了农艺实践,包括叶面施用农用化学品,如化肥和杀虫剂。然而,某些营养物质和非系统农药的韧皮部流动性有限,降低了这些策略的有效性。纳米颗粒(NPs)已经成为一种有希望的载体,通过远距离运输和有针对性地递送必需营养素和活性成分,提高养分利用效率(NUE)和作物保护。虽然越来越多的证据表明,叶面施用的NPs可以在植物内部转移,但对其机制的理解和与农学相关的案例研究仍然很少。因此,NP易位在多大程度上可以促进植物内的显著分布和货物释放尚未完全确定。这篇综述批判性地评估了现有的叶面NP易位研究,强调了植物科学框架内的关键发现。具体来说,我们研究了NP设计如何影响植物内的转运,并评估了现有的NP再动员的定量数据。此外,我们还探讨了生理过程如何影响NP转运,并强调了其他经常被忽视的转运途径。最后,我们评估了目前用于研究NP输运的技术,讨论了它们的适用性和局限性。这篇综述指出了必须解决的重大研究空白,以推进纳米植物营养和作物保护,因此可以用来激励未来的研究。

Translocation of Foliar-Applied Nanoparticles: A Critical Review From a Plant Science Perspective.

Translocation of Foliar-Applied Nanoparticles: A Critical Review From a Plant Science Perspective.

Recent advances in plant science have greatly enhanced agronomic practices involving the foliar application of agrochemicals such as fertilizers and pesticides. However, the limited phloem mobility of certain nutrients and nonsystemic pesticides reduces the effectiveness of these strategies. Nanoparticles (NPs) have emerged as promising carriers to improve nutrient use efficiency (NUE) and crop protection by enabling long-distance transport and targeted delivery of essential nutrients and active ingredients. While increasing evidence suggests that foliar-applied NPs can translocate within plants, a mechanistic understanding and agronomically relevant case studies remain scarce. As a result, the extent to which NP translocation can facilitate significant distribution and cargo release within plants is yet to be fully established. This review critically evaluates existing research on foliar NP translocation, emphasizing key findings within a plant science framework. Specifically, we examine how NP design can influence translocation and assess the existing quantitative data of NP remobilization within plants. Additionally, we explore how physiological processes affect NP transport and highlight alternative, often overlooked translocation pathways. Lastly, we assess current techniques used to study NP transport, discussing their applicability and limitations. This review identifies significant research gaps that must be addressed to advance nano-enabled plant nutrition as well as crop protection and can therefore be used to inspire future research.

期刊介绍: Physiologia Plantarum is an international journal committed to publishing the best full-length original research papers that advance our understanding of primary mechanisms of plant development, growth and productivity as well as plant interactions with the biotic and abiotic environment. All organisational levels of experimental plant biology – from molecular and cell biology, biochemistry and biophysics to ecophysiology and global change biology – fall within the scope of the journal. The content is distributed between 5 main subject areas supervised by Subject Editors specialised in the respective domain: (1) biochemistry and metabolism, (2) ecophysiology, stress and adaptation, (3) uptake, transport and assimilation, (4) development, growth and differentiation, (5) photobiology and photosynthesis.
