Horticultural plants, in particular fruit trees, berry crops, and ornamentals, are valuable objects for studying their genetic and biochemical properties. Along with traditional methods of studying these plants, modern molecular genetic technologies are emerging, in particular genome editing using CRISPR/Cas9 nucleases. In this review, we have analyzed modern advances in genome editing of horticultural plants. To date, it has become possible to improve many plant characteristics using this technology, e.g., making plants resistant to biotic and abiotic stress factors, changing the time of flowering and fruit ripening, changing the growth characteristics of plants, as well as the taste properties of their fruits. CRISPR/Cas9 genome editing has been successfully carried out for many horticultural plants. Dozens of genes from these plants have been modified by means of genome editing technology. We have considered the main ways of delivering genetic constructs to plants as well as limitations that complicate the editing of target genes. The article reviews the prospects of using genome editing to improve the valuable properties of plants important to humans. |
