Research ArticleOpen accessIn the abstractProposal of a Genome Editing System for Genetic Resistance to Tomato Spotted Wilt VirusFederico Martinelli, Giovanni Grillone, Filippo SgroiViruses provoke considerable economical losses in agriculture. New molecular approaches to develop genetic resistance based on translational genomics and precision genetic modifications are highly expected. The type II Clustered, Regularly Interspaced Palindromic Repeats (CRISPR) system including Cas9 nuclease represent a promising and very powerful tool to specifically modulate the expression and activity of genes involved in biotic stress responses.
