PROJECT SUMMARY Gene drives enable a super-Mendelian inheritance where the chance of passing on the gene to the progeny is 100%, and this super-Mendelian inheritance has been demonstrated for several engineered genes in multiple organisms. Gene-drive mediated trait propagation in the entire ecosystem may find use in the elimination of diseases (e.g., malaria, dengue fever) or invasive species, and reversing the pesticide resistance in plants. We propose to use tools and principles of chemistry to develop controllers that will allow us to understand the strength and limitations of the gene drive technologies.

项目摘要 基因驱动使超孟德尔遗传成为可能，其中将基因传递给后代的机会是 100%，这种超级孟德尔遗传已经在多个基因工程中的几个基因中得到证实。 有机体在整个生态系统中，基因驱动介导的性状传播可能会用于消除 疾病（例如，疟疾、登革热）或入侵物种，以及逆转植物对杀虫剂的抗药性。我们 我建议使用化学的工具和原理来开发控制器，使我们能够理解 基因驱动技术的优势和局限性。
