Construction of plants resistant to TYLCV by using artificial zinc-finger proteins.
Previously, we have demonstrated that plant DNA virus replication could be inhibited in Arabidopsis thaliana by using an artificial zinc-finger protein (AZP) and created AZP-based transgenic A. thaliana resistant to DNA virus infection. Here we apply the AZP technology to tomato yellow leaf curl virus (TYLCV) causing serious damage to an important agricultural crop, tomato. An AZP was designed to block binding of the TYLCV replication protein (Rep) to the replication origin. The designed AZP had much higher affinities towards the replication origin than did the Rep, and efficiently blocked Rep binding in vitro. The AZP gene was then introduced into a plant genome with the help of Agrobacterium tumefaciens to generate the transgenic plants. The current status of the construction of the AZP-expressing transgenic plants will be reported.
