Due to recent progress in the development of genetic tools, nematodes have become excellent models to address the mechanistic basis of evolution of development. The gonad is one of the most variable structures in nematodes, reflecting the diverse modes of reproduction and lifestyle in this phylum. During larval development, the gonad primordium has a key role in organizing the neighboring tissues. Therefore, changes in the development of the gonad do not only influence the evolution of its morphology but also the overall body plan of the nematode. Here, we review recent progress on the evolution of development of the germline and somatic gonad in nematodes.
由于遗传工具的最新进展，线虫已成为解决发育进化机制基础的优秀模型。性腺是线虫中最具变异性的结构之一，反映了该门中不同的繁殖和生活方式。在幼虫发育过程中，性腺原基在组织相邻组织方面起着关键作用。因此，性腺发育的变化不仅影响其形态的进化，而且还影响线虫的整体身体计划。在这里，我们回顾了线虫生殖细胞和体细胞性腺发育进化的最新进展。
