罗氏沼虾卵母细胞细胞器与卵黄发生的关系

STUDIES ON THE RELATIONSHIP OF ORGANELLES IN OOCYTE WITH VITELLOGENESIS OF MACROBRACHIUM ROSENBERGII

作者研究了罗氏沼虾卵母细胞细胞器与卵黄发生的关系。细胞核物质通过核孔与细胞质进行物质交换，由核仁而来的核糖体前体物在细胞质中形成大量的核糖体。一部分核糖体附着在内质网囊泡的膜上，形成粗糙型内质网。粗糙型内质同囊泡具有合成和运输卵黄物质的功能。一部分核糖体是游离的，它们可在细胞质中合成致密蛋白质小颗粒，随后这些颗粒逐渐聚集融合成致密的卵黄粒。溶酶体可吞噬这些由游离核糖体形成的蛋白质颗粒团或其它膜状物，并将它们消化、融合，从而形成大的卵黄粒。部分线粒体参与了卵黄粒的合成并最终演变成卵黄体。微丝也参与了卵黄粒的形成。

This thesis described the relationship of organelles in the oocyte withvitellogenesis in Macrobrachium rosenbergii. A large quanhhes of particles from thenucleolus may pass through the nuclear pores into the ooplasm and then form theribosomes, some of which adhere to the membrane to form the rough endoplasmicreticulum (RER). The RER was shown to have funchons of synthesizing andtransmitting yolk materials. A lot of free ribosomes exsiting in cytoplasm provide theplaces for protein synthesizing, and thus form yolk bodies by aggregation and fusionof these proteinous particles. Some mitochondria take part in the production of anddirectly developed into yolk granules. Lysosomes and microfilaments are also involvedin the formation of yolk grannles.
