Tapeworms are a group of more than 10,000 known species adversely affecting the health of both ourselves and our domesticated animals. Their complex life histories centre on the maintenance of a germinative 'neck' region that produces a continuous chain of segments throughout their lives, each replete with male and female reproductive organs capable of producing an enormous number of new infections. Genetic mechanisms underpinning their development are unknown, but have implications for both understanding novel means of therapeutic intervention as well as understanding basic developmental processes in the animal kingdom. This research will examine the roles of Hox and other developmental genes that act to coordinate embryonic axial patterning and other aspects of development throughout the animal kingdom (e.g. establishing which end will develop into the 'head' and which into the 'tail'). By understanding the actions of these genes, this research will resolve fundamental questions regarding how tapeworms became segmented to enable their parasitic lifestyle and how Hox genes are used in the complex development of a parasitic animal. In turn, this will provide a platform for future research on development in other parasitic flatworm groups.

Tapeworms是一组由10,000多种已知物种组成的，对我们自己和我们家养动物的健康都有不利影响。它们复杂的生活历史集中在维持一个发芽的“颈部”区域，该区域一生都会产生连续的细分市场，每一个都充满了能够产生大量新感染的男性和女性生殖器官。基于其发展的遗传机制是未知的，但对了解新颖的治疗干预手段以及了解动物界的基本发展过程具有影响。这项研究将研究HOX和其他发育基因的作用，这些基因在整个动物王国整个动物王国的胚胎轴向图案和发育的其他方面作用（例如，确定最终将发展成“头”和“尾巴”）。通过了解这些基因的作用，这项研究将解决有关如何进行tape虫的细分以使其寄生生活方式以及如何将HOX基因用于寄生动物的复杂发展中的基本问题。反过来，这将为其他寄生虫群中的开发研究提供一个平台。
