土壤纤毛虫喜藤帕森虫皮层纤毛器微管胞器的形态观察

Morphological Observation of Ciliature Microtubular Organelles of Soil Ciliate Pattersoniella vitiphila

应用荧光紫杉醇直接荧光标记,结果表明,土壤纤毛虫喜藤帕森虫(Pattersoniella vitiphila)皮层纤毛器微管胞器中额棘毛基部含极发达的前纵微管束和后纵微管束;迁移棘毛基部含放射状微管和后纵微管束;中腹棘毛基部含放射状微管束;横棘毛基部含前纵微管束;缘棘毛基部含前纵微管束、后纵微管束、横微管束、放射微管和短微管芽;背触毛基体微管由前纵微管和后纵微管组成。腹棘毛基部仅含有呈放射状的基部微管束,其他纤毛虫中未见报道;推测喜藤帕森虫的纤毛器基部微管具有与土壤环境相适应的结构特征。

The microtubular organelles in the cortical ciliature of soil ciliate Pattersoniella vitiphila were visualized by flutax direct fluorescent labeling. It was found that the anterior longitudinal microtubules and the posterior longitudinal microtubules were located in the basal part of frontal cirri, the radiate microtubules accured in transfer cirri and ventral cirri, and the transfer cirri also contained posterior longitudinal microtubules. Anterior longitudinal microtubules were discovered in the basal part of transverse cirri. The anterior longitudinal microtubules, posterior longitudinal microtubules, transeverse microtubules, radiate microtubules and sprout microtubules were visualized in the basal part of marginal cirri. The anterior longitudinal microtubules and posterior longitudinal microtubules were settled in the basal part of dorsal cirri. The result shows that the characteristic of microtubular structure of P. vitiphila was an adaption of soil environment, and it was first reported that ven- tral cirri only contains radiate microtubules in the basal part.
