Considerable advances have been made in the past decade in understanding the mechanisms of virus resistance in plants. In particular, RNA silencing, resistance (R) protein-associated effector triggered immunity (ETI), and recessive resistance (impaired susceptibility), have been at the forefront. While conserved pathogen associated molecular patterns (PAMPs) have generally not been identified in viruses, it is highly likely that virus-encoded glycoproteins or proteins such as the coat protein, and ribonucleoprotein complexes are analogous to PAMPs and can trigger pathogen triggered immunity (PTI)-like responses. More recently, the role of the chloroplast, and its signalling with the nucleus and mitochondrion, has attracted attention in virus resistance studies. Developments in high throughput DNA and RNA sequencing, as well as protein and metabolite technologies, have enabled unravelling of defence responses to virus at a global level, leading to the current belief that resistance mechanisms form a complex of interacting networks. Unravelling these networks will provide opportunities for the next generation of new strategies for plant virus resistance engineering read more ...
