    • The present invention provides an eukaryotic recombinant vector suited for bi-directional transcription of a transgene to yield both sense and antisense RNA transcripts of the transgene in an eukaryotic cell. The invention vectors are particularly suited for mediating gene silencing in a variety of biological systems. The present invention also provides host cells and transgenic plants comprising the invention vectors. Further provided by the invention are methods of inhibiting expression of an endogenous gene present in an eukaryotic cell. Also included is a method of identifying a biological function(s) of an endogenous gene of interest in an eukaryotic cell by selectively inhibiting the expression of the endogenous gene.
    • 本发明提供了适用于转基因双向转录的真核重组载体,以产生真核细胞中转基因的有义和反义RNA转录物。 本发明载体特别适用于介导各种生物系统中的基因沉默。 本发明还提供宿主细胞和包含本发明载体的转基因植物。 本发明进一步提供的是抑制存在于真核细胞中的内源基因表达的方法。 还包括通过选择性抑制内源基因的表达来鉴定真核细胞中感兴趣的内源基因的生物学功能的方法。
