New strategies to control rice viral diseases

Plant viruses cause significant losses in agricultural crops worldwide and affect the yield and quality of agricultural crops. The emergence of new viruses or species through genetic evolution, continuous changes in agricultural practices, synergism of diseases and the effects of global warming are factors that create continuous challenges for the management of epidemics caused by plant virus diseases.

Rice (Oryza sativa L.) is one of the main foods for global consumption. The major obstacle to global rice production is the continuous loss of crops due to plant diseases, including rice blast, pod blight, bacterial blight, and especially a variety of rice viral diseases that are transmitted to other plants through vectors. Since the end of the 19th century, 19 viral pathogens have been known to damage rice production to varying degrees. Of these, 15 cases have been reported from Asia. Among them, Southern Black Vein Dwarf Virus (SRBSDV) and Yellow Mottle Virus Vein Dwarf Virus (RYMV) in Africa and Rice Necrosis Virus (RSNV) in America. It is now a serious threat to rice yield.

The emergence of next-generation sequencing technologies has great potential to identify unknown viruses. Establishing genetic resistance in crops is an effective and desirable method for managing viral diseases. Several dominant and recessive resistance genes have been used to manage virus diseases in crops. Recently, the introduction of resistant cultivars using RNA-based molecular technologies such as RNA interference based on dsRNA and siRNA, microRNA, and CRISPR/Cas9 is done in the development of plants resistant to viral diseases.
