Abstract

Several phytopathogens have detrimental effects on crop production and productivity potentially threatening global food security. Studying the genetic mechanisms of virulence in phytopathogens is vital to assist in their management. Genome editing tools are paving their fascinating roles from the first-generation site-specific nucleases ZNF and TALEN to the current generation clustered regularly interspaced short palindromic repeat (CRISPR)/CRISPR-associated protein9. The discovery of CRISPR/Cas9 has revolutionised the understanding of resistance as well as the susceptibility mechanism against phytopathogens in crop plants. This emerging tool allows researchers to perform precise genome manipulation, genetic screening, regulation, and correction to develop resistance in crop plants with fewer off-target effects. It provides a new opportunity for disease improvement and strengthens the resistant breeding programme. CRISPR/Cas9-based targeted gene manipulation and its enormous application potential as well as the challenges for developing transgene-free disease-resistant crop plants have been discussed in this review. � 2022, The Author(s), under exclusive licence to Springer Nature B.V.
