摘要
涡鞭毛虫(甲藻)类(Dinoflagellate)由于其细胞周期的任何时候核中都含有致密的染色体结构,且其化学组成上缺乏通常真核生物所含的几种组蛋白组份,因而在进化上具有独特的地位。1971年Dodge首次发现波罗底海多甲藻(Peridinium balticum)含有两种不同类型的核,其中大核为涡鞭毛虫类所固有的核,小核却属于真核类型。以后别人又陆续有所发现,但迄今含有两种类型的核的涡鞭毛虫已报道的还是不多的。
We have observed the division of the eucaryotic nucleus of Glenodinium gymnodinium Penard(dinoflagellate).The result showed that in the division process of the eucaryotic nucleus generated the condensation of chromatin and the formation of chromosomes.This is different from that of Peridinium balticum observed by Tippit and Picktt-Heaps(1976).They only found that the division of eucaryotic nucleus belonged to an amitosis and none morphologically distinct chromosomes were observed at any stage of the cell cycle.
