1 The base composition of a virus was found to be 11% A, 32% G, 18% U and 39% C It this a DNA or RNA virus? , Recognition of 5′ triphosphate by RIGI helicase requires short blunt doublestranded RNA as contained in panhandle of negativestrand virus Immunity 31, 25 (09) doi /jimmuni8 pmidRNAdependent RNA polymerase 6 (RDR6) is an essential component of RNAi, which plays an important role in the resistance against viruses in the model plants We found previously that rice RDR6 (OsRDR6) functioned in the defense against Rice stripe virus (RSV), and Rice Dwarf Phytoreovirus (RDV) infection resulted in downregulation of expression of RDR6 a Schematic of the doublestranded RNA
