Insect vectors are the only mobile components in tripartite interactions between plant-virus-vector. The virus alters the biological traits of the vectors in such a manner as to favor virus spread. There are a series of interactions of viral proteins in vector and plant cells. Additionally, every plant-virus-vector interaction is very specific and unique in its characteristics. Little is known about the functions of viral proteins in their vector cells and the role of insect factors interplaying the virus infection, endocytosis, transportation, cellular invasion, and fusion are largely unexplored. Therefore, understanding the critical steps of the virus-vector relationship might help to identify the key targets to interrupt the interrelationship and manage the plant-virus-vector complex. With the advent of next-generation sequencing, omics technologies including genomics, transcriptomics, proteomics, and metabolomics and methods for evaluation of small RNAs have been widely used to elucidate complex molecular mechanisms. Therefore, these technologies offer an unprecedented opportunity to unravel the molecular mechanism involved in virus infection in plants, as well as the processes of acquisition and transmission by insect vectors.
At present pest control largely depends on the host plant resistance and insecticides. However, limited host resistance to virus-vector complexes is known. Insecticides are largely ineffective against several insect vectors and cause health and environmental hazards. Considering the wide range of plant hosts for plant viruses and insect vectors, the development of transgenic varieties is not a feasible option. However, omics can be utilized for better understanding of the pathways and key genes involved in the interrelationship of plant viruses and insect vectors. Indeed, Interrupting the critical steps in their interactions is a novel option for the sustainable control of insect vectors and plant viruses transmitted by them.
This Collection invites all types of novel findings making use of omics to explain molecular mechanisms involved in virus acquisition, internalization, and transmission by insect vectors. We encourage the exploration of plant-virus-vector relationships and characterization of the factors influencing the interactions, plant virus-induced responses of insect vectors, diversity of insect vectors, mechanisms of viral infection in insect vectors and plants, bioactive metabolites, genes, proteins involved in different stages of viral infection, internalization, and release in vectors, functions of viral proteins in insect vectors, transcriptomics, small RNAs, and metabolomics information with the aim of addressing unknown events of plant-virus-vector interactions. We welcome the submission of original research articles. Potential contributions could include, but are not limited to:
- Tracking population outbreaks of insect vectors using mitogenomics
- Genomics in elucidating the mechanisms of virus infection in plants, virus acquisition and transmission by insect vectors, insect proteins in plant virus infection, transportation, endocytosis, and cellular fusion
- Functional role of viral proteins in insect vectors and plants
- Changes in the transcriptome, proteome, and small RNAs profile of the vector and crop plants when infected by the virus
