Abstract
Rice tungro disease (RTD), caused by the co-infection of rice tungro bacilliform virus (RTBV) and rice tungro spherical virus, is one of the most important viral diseases of rice in South and Southeast Asia. The disease remains one of the major threats to sustainable rice production in many countries. The lack of resistance genes to RTBV—the causal agent of tungro disease—makes it even more difficult to manage RTD. In this review, we summarize previous and current research efforts to genetically engineer rice in order to increase the crop’s resistance to tungro disease, including the use of pathogen-derived resistance and of host genes that confer RTD resistance and/or that restrict feeding by the insect vector. The prospects of developing rice cultivars with durable resistance to RTD are also discussed.
