Heritable Virus-Induced Genome Editing (VIGE) in Nicotiana attenuata

Methods Mol Biol. 2023:2606:203-218. doi: 10.1007/978-1-0716-2879-9_16.

Abstract

The CRISPR/Cas9 system is an extremely powerful tool for targeted mutagenesis in plants. However, plant genome editing relies on the labor-intensive plant regeneration method for generating gene-edited plants. To overcome this bottleneck, several virus-induced genome editing (VIGE) techniques have been developed. The VIGE system aims to induce targeted mutations in germ cells without plant regeneration. However, due to the delivery issues of a large Cas9 protein, scientists focus on developing a virus-mediated delivery system for guide RNA into Cas9-overproducing plants. Here, we describe how to induce heritable targeted mutations in a non-model plant, Nicotiana attenuata, using VIGE system. This method will be applied for manipulating the target genes in any plants that scientists are interested in.
