Abstract
Genetic engineering of plants has revolutionized agriculture and has had a significant impact on our everyday life. It has allowed for the production of crops with longer shelf lives, enhanced yields and resistance to pests and disease. The application of nanomaterials in plant genetic engineering has further augmented these programs with higher delivery efficiencies, biocompatibility and the potential for plant regeneration. In particular, subcellular targeting using nanomaterials has recently become possible with the cutting-edge developments within nanomaterials, but remains challenging despite the promise in organellar engineering for the introduction of useful traits and the elucidation of subcellular interactions. This feature article provides an overview of nanomaterial delivery within plants and highlights the application of recent progress in nanomaterials for subcellular organelle-targeted delivery.

Polymer-coated carbon nanotube hybrids with functional peptides for gene delivery into plant mitochondria. Nat Commun 2022; 13:2417. [PMID: 35577779 PMCID: PMC9110379 DOI: 10.1038/s41467-022-30185-y] [Citation(s) in RCA: 17] [Impact Index Per Article: 8.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/21/2021] [Accepted: 04/20/2022] [Indexed: 11/15/2022] Open
Abstract
The delivery of genetic material into plants has been historically challenging due to the cell wall barrier, which blocks the passage of many biomolecules. Carbon nanotube-based delivery has emerged as a promising solution to this problem and has been shown to effectively deliver DNA and RNA into intact plants. Mitochondria are important targets due to their influence on agronomic traits, but delivery into this organelle has been limited to low efficiencies, restricting their potential in genetic engineering. This work describes the use of a carbon nanotube-polymer hybrid modified with functional peptides to deliver DNA into intact plant mitochondria with almost 30 times higher efficiency than existing methods. Genetic integration of a folate pathway gene in the mitochondria displays enhanced plant growth rates, suggesting its applications in metabolic engineering and the establishment of stable transformation in mitochondrial genomes. Furthermore, the flexibility of the polymer layer will also allow for the conjugation of other peptides and cargo targeting other organelles for broad applications in plant bioengineering. The delivery of genetic material into plants is challenging due to the cell wall barrier. Here, the authors hybridize polymer-coated carbon nanotubes with functional peptides to deliver plasmid DNA cargo into intact plant mitochondria for transient expression and homologous recombination at high efficiency.

Abstract
RNA interference, which involves the delivery of small interfering RNA (siRNA), has been used to validate target genes, to understand and control cellular metabolic pathways, and to use as a "green" alternative to confer pest tolerance in crops. Conventional siRNA delivery methods such as viruses and Agrobacterium-mediated delivery exhibit plant species range limitations and uncontrolled DNA integration into the plant genome. Here, we synthesize polyethylenimine-functionalized gold nanoclusters (PEI-AuNCs) to mediate siRNA delivery into intact plants and show that these nanoclusters enable efficient gene knockdown. We further demonstrate that PEI-AuNCs protect siRNA from RNase degradation while the complex is small enough to bypass the plant cell wall. Consequently, AuNCs enable gene knockdown with efficiencies of up 76.5 ± 5.9% and 76.1 ± 9.5% for GFP and ROQ1, respectively, with no observable toxicity. Our data suggest that AuNCs can deliver siRNA into intact plant cells for broad applications in plant biotechnology.

Abstract
Oligoproline-containing peptides, GPPG and GPPPG, were designed and developed for nanoparticle-based delivery platforms, and their degradation is triggered by reactive oxygen species (ROS). Peptides containing more than two consecutive proline residues were found to be cleavable in 1 mM of ROS generated by hydrogen peroxide in the presence of CuSO4, which corresponds to plant cells under photosynthetic conditions. The nanoparticles formed by the peptides were also ROS-degradable and efficiently encapsulated a hydrophobic dye. The hydrophobic cargo in the peptide nanoparticles was released into the cytosol of plant leaf cells in response to the ROS generated in chloroplasts by light irradiation. Furthermore, local laser irradiation enabled the peptide nanoparticles to release their cargo at only the irradiated cell, promising site-selective cargo release triggered by irradiation.

Abstract
In order to improve crop plants in terms of their yield, drought resistance, pest resistance, nutritional value, etc., modern agriculture has relied upon plant genetic engineering. Since the advent of recombinant DNA technology, several tools have been used for genetic transformations in plants such as Agrobacterium tumefaciens, virus-mediated gene transfer, direct gene transfer systems such as electroporation, particle gun, microinjection and chemical methods. All these traditional methods lack specificity and the transgenes are integrated at random sites in the plant DNA. Recently novel techniques for gene targeting have evolved such as engineered nucleases such as Zinc Finger Nucleases, Transcription Activator like effector nucleases, Clustered regular interspaced short palindromic repeats. Other advances include improvement in tools for delivery of gene editing components which include carrier proteins, and carbon nanotubes. The present review focuses on the latest techniques for target specific gene delivery in plants, their expression and future directions in plant biotechnology.

Sci Rep 2018; 8:10966. [PMID: 30030484 PMCID: PMC6054692 DOI: 10.1038/s41598-018-29298-6] [Citation(s) in RCA: 34] [Impact Index Per Article: 5.7] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/14/2018] [Accepted: 07/09/2018] [Indexed: 12/16/2022] Open
Abstract
Cell-penetrating peptides (CPPs) are used for various applications, especially in the biomedical field. Recently, CPPs have been used as a part of carrier to deliver proteins and/or genes into plant cells and tissues; hence, these peptides are attractive tools for plant biotechnological and agricultural applications, but require more efficient delivery rates and optimization by species before wide-scale use can be achieved. Here, we developed a library containing 55 CPPs to determine the optimal CPP characteristics for penetration of BY-2 cells and leaves of Nicotiana benthamiana, Arabidopsis thaliana, tomato (Solanum lycopersicum), poplar (hybrid aspen Populus tremula × tremuloides line T89), and rice (Oryza sativa). By investigating the cell penetration efficiency of CPPs in the library, we identified several efficient CPPs for all the plants studied except rice leaf. In the case of rice, several CPPs showed efficient penetration into rice callus. Furthermore, we examined the relationship between cell penetration efficiency and CPP secondary structural characteristics. The cell penetration efficiency of Lys-containing CPPs was relatively greater in plant than in animal cells, which could be due to differences in lipid composition and surface charge of the cell membranes. The variation in optimal CPPs across the plants studied here suggests that CPPs must be optimized for each plant species and target tissues of interest.
