Abstract:The ciliature microtubular organelles in the ventral cortex of Urostyla grandis were visualized by direct fluorescent labeling of FLUTAX. The organelles consist of the adoral zone of membranelles (AZM), undulating membranes (UM), frontal-midventral-transverse cirri (FVTC), left and right marginal cirri (L-and RMC), and the base-associated microtubules. These base-associated microtubules are comprised of membranelle brackets of AZM, its associated oral rib-wall microtubules, base body brackets of UM, anterior longitudinal microtubules (ALM) and posterior longitudinal microtubules (PLM) of frontal cirri (FC), ALM of TC, ALM, PLM and transverse microtubules (TM) of midventral cirri (VC) and L-and RMC. According to the results, despite the fact that ciliature base-associated microtubules of hypotrichous ciliates have a basic structural component, the composition, differentiation characteristics, location and orientation, and level of development are different. Therefore, the results provide new evidence for the morphology of cortex ciliated cells and diversity of microtubules construction.
