چکیده انگلیسی
Southern rice black-streaked dwarf virus (SRBSDV), a fijivirus, is transmitted by the white-backed planthopper in a persistent-propagative manner. In this study, we found that another planthopper species, the small brown planthopper (SBPH), could acquire SRBSDV but not transmit it. To identify the transmission barrier for SRBSDV in SBPHs, sequential infection by SRBSDV in the organs of SBPHs was studied with immunofluorescence for viral antigens. SRBSDV initially entered the epithelial cells of the midgut, then viroplasms, the sites for viral replication, formed in the midgut of viruliferous SBPHs. Furthermore, SRBSDV spread within the midgut, but failed to disseminate from the midgut into the hemocoel or into the salivary glands. All these results indicated that the inability of SBPH to transmit SRBSDV could be due to the restriction of viral dissemination from the midgut of SBPH, which led to the failure of viral spread to the salivary glands for virus transmission.
