CRISPR/Cas9-mediated editing of eukaryotic elongation factor 1B gamma (eEF1Bγ) reduces Tobacco etch virus accumulation in Nicotiana benthamiana.

ABSTRACT:

Key message

Tobacco etch virus accumulation declined in Nicotiana benthamiana eEF1Bγ gene-edited lines, suggesting that eEF1Bγ may be a host factor for this virus. Viruses use host factors to replicate and move from cell to cell. Therefore, the editing of genes encoding viral host factors that are not essential for plant survival enables the rapid development of plants with durable virus resistance. Eukaryotic initiation factors, such as eIF4E and eIF4G, function as host factors for viral infection, and loss-of-function mutations of these factors lead to virus resistance. Broadening the spectrum of host factor targets would help expand resources for engineering virus resistance. In this study, we tested whether editing the eukaryotic translation elongation factor gene eEF1Bγ would
