About this Research Topic
Viruses are intracellular obligate parasites that rely on host machinery at every stage of the infection cycle including replication, viral migration, and pathogenesis. Plant virus interactions include host and non-host interactions. Host interactions are often compatible interactions, and it results in infection and pathogenesis of the viruses within the host cells. While the non-host interactions are non-compatible interactions, and it does not result in successful virus infection. Plant virus-host interactions result in either host susceptibility or host resistance. In susceptible hosts, viruses take control of highly orchestrated cellular host cellular events by interacting with various host factors and facilitates the virus infection, replication, and disease development in the host plants. In resistant hosts, the virus infection and disease development are highly restricted or limited to the infection site due to plant natural resistance mechanism. Plant immunity to viruses is also mediated by complicated host-virus interactions that are frequently challenging to explain mechanistically. Identification of the host factors that is associated with providing the natural resistance against plants viruses is crucial.
Plants have developed numerous multifaceted defence strategies against virus infection and pathogenesis. Across the world, several research groups are working to decipher the host resistance factors against viruses. On the other hand, understanding how various plant virus-encoded proteins evade host-mediated resistance through novel mechanisms is also exciting. Together, understanding the findings from this area will provide new insights into the development of antiviral strategies against plant viruses. The manuscripts or reviews collected in this Research Topic will run through current knowledge regarding plant-virus interaction, such as providing insights on the following areas: understanding host natural resistance to viruses; identification of host factors involved in virus replication; understanding the host defence response against viruses; and various novel resistance mechanisms that provide resistance against virus infection.
In this Research Topic, we are focusing on studies that help to understand the host-virus interaction, providing insights on the following areas:
• Natural resistance of hosts against viruses.
• Host factors involved in virus replication.
• Host defence responses against viruses.
• Aspects of resistance to virus infection.
