Biography
Dr Jia’s main research focuses on the interaction between rice viruses and their insect vectors. He elucidated the infection routes of SRBSDV and RRSV in different vector planthoppers and used RNAi strategy to investigate gene functions of plant viruses in insect and its culture cells. Using RNAi induced by synthesized dsRNA, Dr Jia found that P9-1 of SRBSDV and Pns10 of RRSV were the constituent of the viroplasm matrix and were essential for viral replication. Tubular structures formed by P7-1 of SRBSDV contained viral particles and participated in viral spread in insect. These studies are useful for understanding the efficiently transmission mechanism of SRBSDV and RRSV in their vectors, and provided theoretical basis and new targets to control viral diseases of rice by RNAi strategy.
