In this study, we have constructed and expressed inverted repeat chimeras from the first exons of the six known hydrophobins of the fungus Cladosporium fulvum, the causal agent of tomato leaf mold. We used quantitative PCR to measure specifically the expression levels of the hydrophobins. The targeted genes are silenced to different degrees, but we also detected clear changes in the expression levels of nontargeted genes. This work highlights the difficulties that are likely to be encountered when attempting to silence more than one gene in a multigene family.
在本研究中,我们构建并表达了来自番茄叶霉病病原菌——黄枝孢菌六种已知疏水蛋白第一个外显子的反向重复嵌合体。我们使用定量PCR专门测量疏水蛋白的表达水平。靶向基因在不同程度上被沉默,但我们也检测到非靶向基因表达水平的明显变化。这项工作突出了在多基因家族中尝试沉默多个基因时可能遇到的困难。
