Transmission of plant virus through arthropod vector

Abstract

The acquisition and transmission of most plant-pathogenic viruses by an insect vector is central to the infection cycle. There are a number of ways to interact plant viruses with their arthropod host including both non-persistent and circulatory transmission, among all some viruses require arthropod vector cells for replication. Plant viruses in the insect host, replicating viruses can also evoke latent as well as adaptive defensive responses. One consistent feature is that the virus interaction with its vector of insects involves complex molecular interactions between virus and host, usually via proteins. Through interfering with virus uptake and transmission, understanding the interactions between plant viruses and their insect host can underpin strategies to protect plants from infection. This review provide a perspective focused on described novel research methods and their promotion for controlling plant viruses by simple understanding and identifying molecular interactions between viruses and insects. We also draw parallels with molecular interactions in animal virus insect vectors, and consider technical advances that may be more widely applicable to plant virus vectors for their control.
