Abstract

Nanotechnology offers a transformative approach to augment plant growth and crop productivity under abiotic and biotic stress conditions. Nanomaterials interact with key phytohormones, triggering the synthesis of stress-associated metabolites, activating antioxidant defense mechanisms, and modulating gene expression networks that regulate diverse physiological, biochemical, and molecular processes within plant systems. This review critically examines the impact of nanoparticles on both conventional and genetically modified crops, focusing on their role in nutrient delivery systems and the modulation of plant cellular machinery. Nanoparticle-induced reactive oxygen species (ROS) generation plays a central role in altering secondary metabolite biosynthesis, highlighting their function as potent elicitors and stimulants in plant systems. The review underscores the significant contribution of nanoparticles in enhancing stress resilience through the modulation of phytohormonal signaling pathways, offering novel insights into their potential for improving crop health and productivity under environmental stressors.

纳米材料对植物激素信号网络的影响

纳米技术提供了一种在非生物和生物胁迫条件下增强植物生长和作物生产力的变革性方法。纳米材料与关键的植物激素相互作用，触发应激相关代谢物的合成，激活抗氧化防御机制，并调节调节植物系统内各种生理、生化和分子过程的基因表达网络。这篇综述批判性地研究了纳米颗粒对传统和转基因作物的影响，重点关注它们在营养输送系统和植物细胞机制调节中的作用。纳米颗粒诱导的活性氧（ROS）的产生在改变次生代谢物的生物合成中起着核心作用，突出了它们在植物系统中作为有效的激发子和兴奋剂的功能。这篇综述强调了纳米颗粒通过调节植物激素信号通路在增强胁迫恢复力方面的重要贡献，为它们在环境胁迫下改善作物健康和生产力的潜力提供了新的见解。

期刊介绍： Plant Science will publish in the minimum of time, research manuscripts as well as commissioned reviews and commentaries recommended by its referees in all areas of experimental plant biology with emphasis in the broad areas of genomics, proteomics, biochemistry (including enzymology), physiology, cell biology, development, genetics, functional plant breeding, systems biology and the interaction of plants with the environment. Manuscripts for full consideration should be written concisely and essentially as a final report. The main criterion for publication is that the manuscript must contain original and significant insights that lead to a better understanding of fundamental plant biology. Papers centering on plant cell culture should be of interest to a wide audience and methods employed result in a substantial improvement over existing established techniques and approaches. Methods papers are welcome only when the technique(s) described is novel or provides a major advancement of established protocols.
