Viral pathogens cause physiological changes in infected plants that lead to different types of host-virus interactions including: compatible interactions, that result in host infection (infectible), and non-compatible interactions, that do not result in host infection (non-host, immune). A compatible interaction results in either host susceptibility - the virus infects the host, replicates in the host, and severe disease symptoms occur - or host resistance - where the virus may or may not replicate in the host to some degree. However, invasion is limited compared to a susceptible host and the apparent disease symptoms are highly localized or do not occur. In general, a host-pathogen (in this case, the virus) dualism remains the fact that, on one hand, plant resistance can be genetically inherited and/or improved by breeding or genetic modification while, on the other hand, the virus itself possesses a counter-defense strategy to convert the host's resistance mechanism.
Viral diseases of plants are difficult to control because these intracellular pathogens use cellular machinery to invade the host. The focus and goal of this Research Topic is to gather comprehensive knowledge on host-virus interactions, from genes to plant fitness as a process of overcoming viral infections and disease severity in crops. The ultimate goal of this Research Topic is to provide a condensed collection of data and knowledge on non-compatible plant-virus interactions, focusing on the mechanism of resistance, sources of resistance, and various molecular aspects of plant resistance to viruses.
This Research Topic welcomes review articles and original research articles that address new findings and current knowledge about plant resistance to viruses. This will cover areas such as:
-natural resistance of crops
-resistance and defense genes
-different resistance mechanisms
-factors involved in defense response
-breeding and new breeding technologies for durable plant resistance
-dominant and recessive resistance
-engineered resistance in plants (especially RNAi-mediated defense)
-gene silencing
-marker-assisted resistance
-signaling pathways related to resistance
-other aspects of crop resistance to viral infections.
Please note that descriptive studies and those defining gene families or descriptive collections of transcripts, proteins, or metabolites, will not be considered for review unless they are expanded and provide mechanistic and/or physiological insights into the biological system or process being studied.
