Article Synopsis
- A survey in Al-Kharj, Riyadh, collected 135 tomato plant samples showing symptoms like mottling and necrosis, identifying TBRV as a significant virus affecting 52.6% of samples, previously undetected in Saudi Arabia.
- Upon confirmation through RT-PCR and sequencing, the study revealed a close phylogenetic relationship between Saudi TBRV isolates and those from Poland, but a more distant relation to those from England and Lithuania.
- This research provides the first report of TBRV's presence in tomato plants in Saudi Arabia and contributes to understanding the virus's molecular characteristics.
