摘要显微外科达到冠状假性频尿柱 克里斯蒂塔)无小核系中,分得的财产细胞因口围带交换部小膜呈现不一样度的残缺而理由畸形的部分;在细胞追溯不变的期的群体中,口围带畸形的部分率高达50%由于;对无小核系600多个刚执行二分裂生殖的前、后邋遢人和1 1000多种虫生理后期蛋白质的银染,除4只二歧化邋遢人和3只二歧化邋遢人出入口周带非常外,压倒的多数表示保留或保存时用以图案装饰产生后的细胞都具有有规律的的胞口体系.在另一方面,专一性培育试验而且显示,出入口周畸形的部分产生在非以图案装饰产生阶段。,损失小核的细胞,同时也损失了胞口体系的稳定性.To explore the generality of the morphogenetic function of the micronucleus among ciliates, we employed five stocks of hypotrichous ciliate Pseudourostyla 克里斯蒂塔 : 2, 4, 6, 28 and 46, and five a小核 cell lines:2aml, 4aml, 6aml, 28aml and 46aml derived from stocks 2, 4, 6, 28 and 46 respectively, which were generated by amputation of the cell when the micronuclei became aligned on the left side of the amalgamated macronuclei during cell 机关。 小核 cell lines 2ml, 4ml, 28ml and 46ml derived after amputation but retaining the micronuclei were also studied and served as 把持。 For observation of the cortex and nuclei, protargol staining was used 从头到尾。 The evident character of the a小核 cell lines, as compared with the normal and the 小核 cell lines, was that a substantial proportion of cells exhibited an abnormal adoral zone of membranelles (阿兹姆) When the culture medium began to age after 7~10 days, the culture soon entered stationary phase of 增长。 During the period abnormal AZMs were observed in over 50% of a小核 cells in various cell lines, among which the percentage of 6aml cells with defective AZM came up to 98%. In fact, the percentage of cells with abnormal AZM in a culture population was changeable and varied from low to high from exponential growth phase to stationary 阶段。 These abnormal patterns involved various degrees of reduction of membranellar width in the anterior and middle part of the AZM lapel (阿兹姆 L), and in severe cases disruption of AZM continuity due to the loss of some membranelles, and also indentation of the cytoplasm in this 区域。 Morphogenesis of the a小核s in binary fission and in physiological reorganization was 当观察员。 Restructuring of the pre existing oral apparatus, both during binary fission in the putative proter and during physiological reorganization, resulted in the formation of a normal 阿兹姆。 After restoration of normal AZM in binary fission or physiological reorganization, abnormal AZM pat
