Genetically Modified Plants and Crops Can Contribute to Remarkable Increase in Global Food Supply, with Improved Yield and Resistance to Plant Diseases or Insect Pests. the Development of Biotechnology Introducing Exogenous Nucleic Acids in Transgenic Plants is Important for Plant Health Management. Different Genetic Engineering Methods for DNA Delivery, Such as Biolistic Methods, Agrobacterium Tumefaciens-Mediated Transformation, and Other Physicochemical Methods Have Been Developed to Improve Translocation Across the Plasma Membrane and Cell Wall in Plants. Recently, the Peptide-Based Gene Delivery System, Mediated by Cell-Penetrating Peptides (CPPs), Has Been Regarded as a Promising Non-Viral Tool for Efficient and Stable Gene Transfection into Both Animal and Plant Cells. CPPs Are Short Peptides with Diverse Sequences and Functionalities, Capable of Agitating Plasma Membrane and Entering Cells. Here, We Highlight Recent Research and Ideas on Diverse Types of CPPs, Which Have Been Applied in DNA Delivery in Plants. Various Basic, Amphipathic, Cyclic, and Branched CPPs Were Designed, and Modifications of Functional Groups Were Performed to Enhance DNA Interaction and Stabilization in Transgenesis. CPPs Were Able to Carry Cargoes in Either a Covalent or Noncovalent Manner and to Internalize CPP/cargo Complexes into Cells by Either Direct Membrane Translocation or Endocytosis. Importantly, Subcellular Targets of CPP-Mediated Nucleic Acid Delivery Were Reviewed. CPPs Offer Transfection Strategies and Influence Transgene Expression at Subcellular Localizations, Such as in Plastids, Mitochondria, and the Nucleus. in Summary, the Technology of CPP-Mediated Gene Delivery Provides a Potent and Useful Tool to Genetically Modified Plants and Crops of the Future.
