Rice Responses and Resistance to Planthopper-Borne Viruses at Transcriptomic and Proteomic Levels

Feng Cui, Wan Zhao, Lan Luo and Le Kang

Rice (Oryza sativa) is one of the most important cereal crops in the world, especially in Asian areas. Rice virus diseases are considered as the most serious threat to rice yields. Most rice viruses are transmitted by hemipteran insects such as planthoppers and leafhoppers. In Asia five rice viruses are transmitted mainly by three planthopper species in a persistent manner: Rice stripe virus, Rice black-streaked dwarf virus, Rice ragged stunt virus, Rice grassy stunt virus, and Southern rice black-streaked dwarf virus. In rice antivirus studies, several individual genes have been shown to function in rice resistance to viruses. Since plant responses to viral infection are complex, system-level omic studies are required to fully understand the responses. Recently more and more omic studies have appeared in the literatures on relationships between planthoppers and viruses, employing microarray, RNA-Seq, small RNA deep sequencing, degradome sequencing, and proteomic analysis. In this paper, we review the current knowledge and progress of omic studies in rice plant responses and resistance to four planthopper-borned viruses. We also discuss progress in the omic study of the interactions of planthoppers and rice viruses. Future research directions and translational applications of fundamental knowledge of virus-vector-rice interactions are proposed.
