Most naked basal bodies visualized in protargol stains on the surface of Tetrahymena are new basal bodies which have not yet developed cilia. The rarity of short cilia is explained by the rapid development of the ciliary shaft once it begins to grow. The high frequency of naked basal bodies (about 50 percent) in log cultures indicates that the interval between assembly of the basal body and the initiation of the cilium is long, approximately a full cell cycle. Naked basal bodies are more frequent in the mid and posterior parts of the cell and two or more naked basal bodies may be associated with one ciliated basal body in these regions. Daughter cells produced at division are apparently asymmetric with respect to their endowment of new and old organelles.
在嗜银染色中,在四膜虫表面观察到的大多数裸露基体是尚未发育出纤毛的新基体。短纤毛的稀少是由于纤毛轴一旦开始生长就迅速发育。对数生长期培养物中裸露基体的高频率(约50%)表明,基体组装与纤毛起始之间的间隔很长,大约为一个完整的细胞周期。裸露基体在细胞的中部和后部更为常见,在这些区域,两个或更多的裸露基体可能与一个有纤毛的基体相关联。分裂产生的子细胞在新细胞器和旧细胞器的分配方面显然是不对称的。
