Plant Resistance to Infection by Viruses

Abstract

Damages caused by viruses have a major economic and agronomic impact in agriculture. To counter these attacks, plants have developed efficient defence mechanisms that prevent or limit viral infection. Recently, important advances in our understanding of the molecular nature and mechanisms associated with recessive or dominant natural virus resistance genes have been made, as well as concerning the general antiviral defence system based on ribonucleic acid (RNA) silencing.

“…Most of the r genes encode translational factors of the 4E and 4G families, and the resistance in this case is due to the presence of a mutated version or to the absence of that factor. Recessive resistance has been described for Bymo-, Carmo-, Cucumo-, Ipomo-, Poty-and Sobemovirus genus (Revers and Nicaise, 2014).…”
