Previous genetic pest management (GPM) systems in diamondback moth (DBM) have relied on expressing lethal proteins (‘effectors’) that are ‘cell-autonomous’, that is, they do not leave the cell in which they are expressed. To increase the flexibility of future GPM systems in DBM, we aimed to assess the use of a non-cell-autonomous, invertebrate-specific, neurotoxic effector – the scorpion toxin AaHIT. This AaHIT effector was designed to be secreted by expressing cells, potentially leading to effects on distant cells, specifically neuromuscular junctions.

无脊椎动物特异性蝎子毒素 AaHIT 的工程表达降低了小菜蛾 Plutella xylostella 的成虫寿命和雌性繁殖力

以前的小菜蛾 (DBM) 遗传害虫管理 (GPM) 系统依赖于表达“细胞自主”的致死蛋白(“效应子”),也就是说,它们不会离开表达它们的细胞。为了提高未来 GPM 系统在 DBM 中的灵活性,我们旨在评估非细胞自主、无脊椎动物特异性、神经毒性效应物——蝎子毒素 AaHIT 的使用。这种 AaHIT 效应器被设计为通过表达细胞分泌,可能导致对远处细胞的影响,特别是神经肌肉接头。
