Nanomaterials in plant management: functions, mechanisms and prospects

Abstract

Efficient, sustainable agricultural methods are critical to meet the food requirements of a rapidly growing global population.

Nanotechnology in Agriculture: Manganese Ferrite Nanoparticles as a Micronutrient Fertilizer for Wheat

“…The counterpart fertilizer treatments (ION) were increased by 13% (from 4.2 ± 0.4 to 4.7 ± 0.26) (Figure 3d). Those results show the possibility that nanoparticles can stimulate the expression of plant-related genes [10]. For instance, the application of chitosan nanoparticles on wheat induces the expression of auxin-related genes, expedites the biosynthesis and transportation of indoleacetic acid (IAA), and elevates IAA concentrations in wheat tissues, thereby exerting a positive impact on plant growth [39].…”

“…Therefore, researchers focus on enhancing plant nutrient uptake efficiency by refining the chemical fertilizers. Recently, studies have shown that under equivalent ionic concentrations, nano-fertilizers composed of macronutrients or micronutrients exhibit higher efficiency than traditional fertilizers and demonstrate the effective reduction of nutrient leaching [9,10].…”

Mechanistic approaches for crosstalk between nanomaterials and plants: plant immunomodulation, defense mechanisms, stress resilience, toxicity, and perspectives

“…Specialized research providing insights into these inquiries will facilitate the development of innovative nanomaterials with controlled physicochemical properties to support the agricultural management strategies. 264 However, despite the attention given to the prospective benefits of nanomaterials in plant management, there remain numerous obstacles that must be surmounted to fully exploit the capabilities of nanomaterials-enabled technologies for plants. For example, nanomaterials effect on plants majorly depends on exposed concentration and it may cause adverse effects if exceeded beyond a certain limit.…”

Fostering sustainable agriculture: genotype-independent plant cell transfection mediated by piezoelectric nanomaterials via sonoporation

“…[35][36][37][38][39][40] These include their ability to interact with DNA, providing protection against mechanical and enzymatic shearing, as well as facilitating the transfer of macromolecules into intact plant cells. [41][42][43][44] There have been limited accounts regarding the application of nanocarriers in sonication-mediated DNA delivery into protoplasts and intact plant cells, reported across various plant species. 12,17,18,42,45 These approaches offer advantages such as cost-effectiveness, species independence, and simplicity.…”
