研究了赤霉（Chilodonella uncinata Ehrenberg, 1838）细胞发生过程中气孔的形成和皮层的发育。在造口过程中涉及五种躯体运动。它们中的每一个都产生一个动性收缩。这些着丝细胞片段是口服动力学和胞浆的抗原复合物。体细胞单动素是气孔发生的基本单位。奇洛多纳菌形态发生的基本特征与大多数细胞体相似：旧的口腔器官保留在蛋白质中；新口腔原基（OP）起源于左躯体运动。其形态发生始于背动肌（DBA）的出现。原基野位于体细胞纤毛的左野。最里面的5个左动素片段，每个发育1个动素片段（anage），从右到左编号为1 ~ 5（图2:A中只标记了3个anlagen）。着丝碎片1是口前运动的样本，着丝碎片2是内环运动的样本。动分裂体3、4和5一起是外环动的分支。
The stomatogenesis and cortical development during the cell ontogeny in Chilodonella uncinata Ehrenberg, 1838 have been investigated. In stomatogenesis five somatic kineties are involved. Each of them produces one kinetofiagment. These kinetofragments are anla-gen-complexes for the oral kineties and cyrtos. The somatic monokinetid is the elementary unit of stomatogenesis.The basic characteristics of the morphogenesis of Chilodonella uncinata are similar to those exhibited by most cyrtophorids: the old oral apparatus remains in the proter; the new oral primordium (OP) of opisthe originates from the left somatic kineties.The morphogenesis starts with the appearence of the anlage of dorsal kinety (DBA). The primordium field is situated in the left field of the somatic ciliature. The five innermost left kineties segment and develop one kinetoframent (anlage) each, which are numbered 1 to 5 from right to left (in the figure 2:A only 3 anlagen are marked). Kinetofragment 1 is the anlage of the preoral kinety and kinetofragment 2 is the anlage of the inner circumoral kinety. Together the kinetoframents 3, 4 and 5 are the anlage of the outer circumoral kinety.
