Abstract
Transcriptome analyses of rice genes infected by eight rice viruses (RDV, RRSV, RBSDV, RSV, RGSV, RTYV, RTSV and RTBV) were done. Severe disease signs of infection were observed after RDV and RSV, while in the cases of RTYV and RTSV disease signs were not observed. Numbers of the up- and down-regulated genes were well correlated with the intensity of disease sign. Host genes were classified into the metabolic pathways, transcription, translation, protein processing processes, family of transcription factors, biosynthesis of phytohormones and responsive genes to phytohormones. According to these classifications, what happened in infected cells were analyzed. As for cell-cycle related genes, CycB genes were down-regulated in many virus infections. As for transcription factors, AP2-EREBP, Tify, WRKY families were actively changed after virus infection and they were further classified into some subfamilies by the up- and down-changes. Gene expression profiles of RTSV- and RTBV susceptible (Taichung Native 1) and resistant hosts (TW16: NIL originated from Utri Merah) will also be reported.
