Resumen
Viruses are silent enemies that intrude and take control of the plant cell?s machinery for their own multiplication. Infection by viruses and the resulting damage is still a major challenge in the agriculture sector. Plants have the capability to fight back, but the ability of viruses to mutate at a fast rate helps them to evade the host?s response. Therefore, classical approaches for introgressing resistance genes by breeding have obtained limited success in counteracting the virus menace. Genetic modification (GM)-based strategies have been successful in engineering artificial resistance in plants. Several different approaches based on pathogen-derived resistance, antisense constructs, hairpin RNAs, double-stranded RNA, etc., have been used to enhance plants? resistance to viruses. Recently, genome editing (GE) strategies mainly involving the CRISPR/Cas-mediated modifications are being used for virus control. In this review, we discuss the developments and advancements in GM- and GE-based methods for tackling viral infection in plants.
