摘要

摘要线虫是发育研究的优秀模型，具有许多有利的特性。Rhabditidae家族是一组在性腺结构、繁殖方式、卵裂模式等方面表现出多样性的食菌线虫。在本文中，Rhabditdae的两个物种，即Poucipapillata Paetzold Mesorhabditis，1955和Cephaloboides anisospiculus Tahsee et al.，2017，分别具有性腺单倍体和双倍体类型，被选择用于性腺发育的胚胎模式和趋势的比较分析。在C.anisospiculus的AB系中连续三次分裂后，观察到早期细胞系的分裂模式随着EMS的分裂而显著变化。性腺发育的模式不同，分支的数量是决定原基形状和方向的关键因素；相反，外阴的形成在很大程度上取决于外阴开口的位置和形状。

A comparative account of the embryonic lineage and gonad development in two species of Rhabditidae (Nematoda)

ABSTRACT Nematodes serve as excellent models for developmental studies, with a good number of favourable properties. The family Rhabditidae is a paraphyletic group of bacterivorous nematodes showing diversity in the structure of gonads, mode of reproduction, cleavage pattern, etc. In the present paper, two species of Rhabditidae, namely Mesorhabditis paucipapillata Paetzold, 1955 and Cephaloboides anisospiculus Tahseen et al., 2017, with monodelphic and didelphic types of gonads, respectively, were selected for a comparative analysis of the embryonic patterns and trends in gonad development. The cleavage patterns of the early cell lineages were observed to vary considerably with the division of EMS after three consecutive divisions in the AB line in C. anisospiculus. The patterns of gonad development differed, with the number of branches being the key factor in determining the shape and orientation of the primordium; in contrast, vulva formation largely depended on the position and shape of the vulval opening.

期刊介绍： Journal of Natural History is an international zoological journal publishing original research and reviews in evolutionary biology and ecology. It maintains its historical niche by publishing a broad range of systematics papers on all animal phyla from Porifera to Chordata, encompassing traditional taxonomic revisions and descriptions, cladistic analyses and molecular phylogenetics and phylogenomics. The journal has recognized strengths in entomology and marine invertebrates, but also welcomes papers on the natural history of all animal species and on the interactions of species with their environment. Preference is given to in-depth papers and extensive taxonomic reviews: single species descriptions and checklists are not normally considered. Authors wishing to suggest a review paper should contact the relevant editor.
