In vitro transcripts from RNA5 wild type clone were co-inoculated into Tetragonia expansa with the RNAs of Hu3 isolate containing RNA1, 2 and 3. Following RT-PCR and Northern blotting results shows RNA5 could be biologically replicated in the leaves. The virus concentration of the isolate containing RNA5 in T. expanxa was higher than that of the isolate Hu3 evaluated by ELISA detection.

野生型RNA5的体外转录物与含Hu3(RNA1+2+3)分离物的总RNA混合接种番杏叶片的RT-PCR和Northern blot检测结果都表明，野生型RNA5能够在接种寄主体内复制，并且ELISA检测证明含有RNA5的番杏病叶中病毒浓度高于不含RNA5病叶的病毒浓度。

Objective To study the effect of Borna disease virus infection on the transcription of monoaminergic receptor genes in the brain tissues of neonatally inoculated rats.
