Abstract
The disease caused by Tomato zonate spot virus (TZSV), transmitted by Frankliniella occidentalis in a circulative-propagative manner, results in significant loss in production and quality in ornamentals and vegetable crops. Related to this recently found tospovirus (TZSV), knowledge involving the interaction between virus, vector, and host plants remains unknown. In this study, we investigated the effects of TZSV infection on the changes in concentration of the plant hormones jasmonic acid (JA) and salicylic acid (SA), and the transcriptional regulation of JA- and SA-associated genes. Additionally, we verified that JA and SA inhibit the fitness of the vector F. occidentalis. This work brings to a new perspective on plant—virus–vector interactions is proposed, which could be applied to control the TZSV infection.
