Nanoparticle-Mediated Nucleic Acid Delivery Systems in Plant Biotechnology: Recent Advances and Emerging Challenges

Résumé fourni par la source

-mediated transformation, gene gun bombardment, and electroporation have been widely applied in plant genetic engineering, these systems exhibit limitations including species-dependent efficacy, propensity to cause plant tissue damage, low transformation efficiency, susceptibility to environmental factors. In recent years, with the advancement of nanotechnology, nanoparticle-based nucleic acid delivery systems are emerging as novel tools for applications such as novel tools for dsRNA or transgene delivery. These systems leverage the unique physicochemical properties of nanomaterials, including size-dependent phenomena, tunable surface charge, and enhanced membrane penetration capabilities, to achieve targeted delivery and stable expression of genetic payloads. Nevertheless, nanomaterial-mediated gene delivery systems for plants are still in their nascent stages, and their widespread application faces numerous challenges. This article briefly introduces traditional delivery methods, systematically reviews the applications and progress of nanoparticle-based nucleic acid delivery systems, and discusses the cross-species applicability of nanoparticles, as well as the associated biosafety concerns. We aim to offer insights for tackling the prevailing technical bottlenecks and to provide guidance for the rational design of nanomaterials that efficiently traverse the plant cell wall-plasma membrane barrier and stably deliver nucleic acids without eliciting phytotoxicity.
