埃及伊蚊的性别决定由位于称为 M 基因座的 Y 染色体样区域内的显性雄性决定因子(M 因子)控制。在这里,我们展示了 M 位点基因 Nix 在埃及伊蚊中充当 M 因子。 Nix 表现出持久的 M 连锁和早期胚胎表达,这是 M 因子所需的两个特征。使用成簇规则间隔短回文重复序列 (CRISPR)–Cas9 进行的 Nix 敲除导致了雄性基因很大程度上女性化,并产生了性分化的两个关键调节因子的雌性亚型:双性和无果。 Nix 的异位表达导致遗传性女性具有几乎完整的男性生殖器。因此,Nix 对于启动雄性发育来说既是必需的,也是充分的。这项研究为将雌性蚊子转变为无害的雄性蚊子的蚊子控制策略奠定了基础。
Sex determination in the mosquito Aedes aegypti is governed by a dominant male-determining factor (M factor) located within a Y chromosome–like region called the M locus. Here, we show that an M-locus gene, Nix, functions as an M factor in A. aegypti. Nix exhibits persistent M linkage and early embryonic expression, two characteristics required of an M factor. Nix knockout with clustered regularly interspaced short palindromic repeats (CRISPR)–Cas9 resulted in largely feminized genetic males and the production of female isoforms of two key regulators of sexual differentiation: doublesex and fruitless. Ectopic expression of Nix resulted in genetic females with nearly complete male genitalia. Thus, Nix is both required and sufficient to initiate male development. This study provides a foundation for mosquito control strategies that convert female mosquitoes into harmless males.
