Abstract

Nanomaterials usually have specific characteristics due to their incredibly tiny size, which also increases their surface area, providing a more interactive surface. Compared to their macro-sized counterparts, these tiny nanoparticles exhibit a multitude of size-dependent properties. Plant tissue culture (PTC) plays an important role in bioactive chemical synthesis, mass cultivation, protection, genetic control, and plant enhancement. Different nanoparticles (NPs) are utilized to improve the tissue culture responses of explants. Various nanoparticles, including cobalt, copper, silver, gold, zinc, selenium, titanium, iron, palladium, cerium, indium, manganese, aluminum, barium, silicon, nickel, zirconium, and their oxides, are used in this regard. Nowadays, it is critical to use nanosystems in conjunction with PTC for mass reproduction, conservation, genetic engineering, crop enhancement, and the synthesis of bioactive compounds. Nanostructured metal oxides play an important role in in vitro plant cultivation. The use of metal nanoparticles (MNPs) has successfully removed microbial contaminants from explants and had a favorable impact on organogenesis (increasing the growth of shoots, roots, and multiplication ratios), callus induction, metabolic changes, and the synthesis of secondary metabolites (NPs are used as elicitors or stress agents). Additionally, NPs cause somaclonal variation (modifications to DNA), improve cryopreservation (increasing the survival rate), and enhance genetic transformation (facilitating gene transformation to bypass the plant cell wall barrier and accelerating protoplast isolation). This review aims to summarize the current breakthroughs achieved by integrating nanotechnology with PTC.

金属纳米颗粒在离体条件下植物器官形成、次生代谢物产生和遗传转化中的作用:综述
纳米材料通常因其难以置信的微小尺寸而具有特殊的特性,这也增加了它们的表面积,提供了一个更具交互性的表面。与宏观尺寸的同类产品相比,这些微小的纳米颗粒表现出多种与尺寸有关的特性。植物组织培养(PTC)在生物活性化学品合成、大规模栽培、保护、遗传控制和植物强化方面发挥着重要作用。不同的纳米颗粒(NPs)可用于改善外植体的组织培养反应。各种纳米粒子,包括钴、铜、银、金、锌、硒、钛、铁、钯、铈、铟、锰、铝、钡、硅、镍、锆及其氧化物,都被用于这方面。如今,将纳米系统与 PTC 结合用于大规模繁殖、保护、基因工程、作物增产和生物活性化合物的合成至关重要。纳米结构的金属氧化物在体外植物培育中发挥着重要作用。金属纳米颗粒(MNPs)的使用已成功清除了外植体中的微生物污染物,并对器官发生(增加芽、根的生长和繁殖率)、胼胝体诱导、代谢变化和次生代谢物的合成(NPs 可用作诱导剂或胁迫剂)产生了有利影响。此外,NPs 还能引起体细胞变异(DNA 的改变)、改善低温保存(提高存活率)和加强基因转化(促进基因转化以绕过植物细胞壁屏障并加速原生质体的分离)。本综述旨在总结目前通过将纳米技术与 PTC 相结合而取得的突破性进展。

期刊介绍: This journal highlights the myriad breakthrough technologies and discoveries in plant biology and biotechnology. Plant Cell, Tissue and Organ Culture (PCTOC: Journal of Plant Biotechnology) details high-throughput analysis of gene function and expression, gene silencing and overexpression analyses, RNAi, siRNA, and miRNA studies, and much more. It examines the transcriptional and/or translational events involved in gene regulation as well as those molecular controls involved in morphogenesis of plant cells and tissues. The journal also covers practical and applied plant biotechnology, including regeneration, organogenesis and somatic embryogenesis, gene transfer, gene flow, secondary metabolites, metabolic engineering, and impact of transgene(s) dissemination into managed and unmanaged plant systems.
