从形态学不同到基因水平差异:家蚕与果蝇早期胚胎发育比较

Comparison of Early Embryogenesis Between Silkworm and Drosophila from both Morphology and Gene Content Level

昆虫的分化多样性一直是研究的一个热点,对家蚕胚胎发育调控机制的研究将有助于加深人们对其他昆虫早期胚胎发育机制的了解。文章综述了鳞翅目昆虫家蚕和双翅目昆虫果蝇的早期胚胎发育在形态学及基因水平的研究结果。通过比较,发现二者的早期胚胎发育存在较大差异。这一结果不但可以为家蚕胚胎发育调控机制的分子水平研究提供重要参考,也可为昆虫分化多样性的分子机制研究提供线索。

The diversity of insects has been the focus of many investigations. Research in the early embryonic developmental mechanism of silkworm will promote understanding in early embryonic developmental mechanism of other insects. This paper reviews the differences in early embryonic development of silkworm and Drosophila from both morphology and gene content level. The results not only provide evidences for the study of early embryonic development mechanism in silkworm, but also give clues for the study of insects diversity.
