Full-length RNA sequencing reveals the mechanisms by which an TSWV-HCRV complex suppresses plant basal resistance

Viruses deploy numerous strategies to infect plants, typically by forming a complex with another virus, leading to more efficient infection. However, the detailed plant responses to viral infection and the underlying mechanisms of co-infection remained unclear. Previously, we found that Tomato spotted wilt orthotospovirus (TSWV) and Hippeastrum chlorotic ringspot orthotospovirus (HCRV) could infect plants in the field by forming a complex. In this study, we found that TSWV infected tobacco (Nicotiana benthamiana) plants in cooperation with HCRV, leading to a more efficient infection rate of both viruses.
