While interactions between viruses and their vectors, as well host plants, have been extensively studied, the genetic mechanisms underlying tripartite remain largely unknown. In this study, phenotypic assays are integrated with molecular biology functional genomic approaches to elucidate involving tomato chlorosis virus (ToCV), a major threat production worldwide, whitefly, Bemisia tabaci, an insect vector, plants. ToCV infection induces of chlorophyll degradation product that acts volatile attractant for whiteflies. Furthermore, suppression Lhca4, gene encoding subunit light-harvesting complex I in by P9 protein leads neophytadiene biosynthesis. Overexpression Lhca4 reduced infection. OBP2, odorant-binding from B. capable binding is identified. Suppression BtOBP2 impaired vector's subsequent preference ToCV-infected The results not only reveal underpinnings, including P9, plant whitefly BtOBP2, governing virus-vector-plant interactions, but also highlight neophytadiene, specialized metabolite mediator intricate multitrophic suggesting new avenues managing vectored insects.
