Transovarial Transmission of a Plant Virus Is Mediated by Vitellogenin of Its Insect Vector
Figure 6
Quantitative assay of RSV in dsRNA-injected ovarioles.
RSV-infected nymphs were injected with Vg dsRNA, with gfp dsRNA as a control. a: After dsRNA injection, insects that had emerged for 48 hours were selected to detect Vg expression. b: The quantity of RSV pc3 RNA had decreased significantly by 79% in the ovarioles of viruliferous 48 h adult insects. c: RSV level in the other parts of the insect body did not decrease after injections with different dsRNAs.
