Anopheles gambiae, the main mosquito vector of human malaria, is a challenging organism to manipulate genetically. As a consequence, reverse genetics studies in this disease vector have been largely limited to RNA interference experiments. Here, we report the targeted disruption of the immunity gene TEP1 using transgenic expression of Transcription-Activator Like Effector Nucleases (TALENs), and the isolation of several TEP1 mutant A. gambiae lines. These mutations inhibited protein production and rendered TEP1 mutants hypersusceptible to Plasmodium berghei. The TALEN technology opens up new avenues for genetic analysis in this disease vector and may offer novel biotechnology-based approaches for malaria control.
冈比亚按蚊是人类疟疾的主要传播媒介,是一种在基因操作上颇具挑战性的生物体。因此,在这种病媒中进行的反向遗传学研究在很大程度上仅限于RNA干扰实验。在此,我们报告了利用转录激活样效应核酸酶(TALENs)的转基因表达对免疫基因TEP1进行靶向破坏,并分离出了多个TEP1突变的冈比亚按蚊品系。这些突变抑制了蛋白质的产生,使TEP1突变体对伯氏疟原虫高度敏感。TALEN技术为这种病媒的遗传分析开辟了新途径,并可能为疟疾控制提供基于生物技术的新方法。
