| 1 | Post-transcriptional Gene Silencing Induced by Short Interfering RNAs in Cultured Transgenic Plant Cells显示文摘Short interfering RNA (siRNA) is widely used for studying post-transcriptional gene silencing and holds great promise as a tool for both identifying function of novel genes and validating drug targets. Two siRNA fragments (siRNA-a and -b), which were designed against di?erent speci?c areas of coding region of the same target green ?uorescent protein (GFP) gene, were used to silence GFP expression in cultured gfp transgenic cells of rice (Oryza sativa L.; OS), cotton (Gossypium hirsutum L.; GH), Fraser ?r [Abies fraseri (Pursh) Poir; AF], and Virginia pine (Pinus virginiana Mill.; PV). Di?erential gene silencing was observed in the bom- barded transgenic cells between two siRNAs, and these results were consistent with the inactivation of GFP con?rmed by laser scanning microscopy, Northern blot, and siRNA analysis in tested transgenic cell cultures. These data suggest that siRNA-mediated gene inactivation can be the siRNA speci?c in di?erent plant species. These results indicate that siRNA is a highly speci?c tool for targeted gene knockdown and for establishing siRNA-mediated gene silencing, which could be a reliable approach for large-scale screening of gene function and drug target validation. | WeiTang VanessaSamuels NickiWhitley NicoleBloom TinyaDeLaGarza RonaldJ.Newton | 2004 | Genomics, Proteomics & Bioinformatics2004，2，2： | 4 |
