The oral apparatus of tetrahymena pyriformis strain wh 6 part 4 observations on the organization of micro tubules and filaments in the isolated oral apparatus and the differential effect of potassium chloride on the stability of oral apparatus micro tubules

An ultrastructural analysis of the organization of the isolated oral apparatus of T. pyriformis, strain WH-6, syngen 1, with emphasis on the organization of microtubules and filaments in oral apparatus membranelles was carried out. Oral apparatus membranellar basal bodies were characterized with respect to structural differentiations at the distal and proximal ends. The distal region of membranellar basal bodies contained the basal plate, accessory microtubules and filaments. The proximal end contained a dense material from which emanate accessory microtubules and filaments. There were at least 2, possibly 3 different arrangements of accessory structures at the proximal end of membranellar basal bodies. All membranellar basal bodies appeared to have a dense material at the proximal end from which filaments emanate. Some of these basal bodies have accessory microtubules and filaments emanating from this dense material. A possible 3rd arrangement was represented by basal bodies which had lateral projections, from the proximal end, of accessory microtubules and filaments which constituted cross or peripheral connectives. There were at least 3 examples of direct associations between oral apparatus microtubules and filaments: filaments which formed links between basal body triplet microtubules; filaments which linked the material of the basal plate to internal basal body microtubules; and filaments which linked together microtubule bundles from membranellar connectives. KCl extraction of the isolated oral apparatus resulted in the selective solubilization of oral apparatus basal bodies, remnants of ciliary axonemes and fused basal plates. Based on their response to KCl extraction, 2 distinct sets of morphologically similar microtubules could be identified: microtubules which constituted the internal structure of basal bodies and ciliary axonemes, and those which constitute the fiber connectives between basal bodies.
