"The morphology of the cytoskeleton (microtubules and actin) in the cells during the life cycle and in the protoplasts of the yeast Schizosaccharomyces japonicus var. versatilis were studied. Three types of microtubules were observed : (i) interphase microtubules (MTs) consisting of microtubule bundles arranged in parallel to the longitudinal cell axis; (ii) spindle microtubules involved in karyokinesis and (iii) astral microtubules emanating from the poles of the spindle at the end of mitotic anaphase and after meiosis I and II. The astral MTs were responsible for migration of the nucleus into the conjugation projection during mating, and facilitated contact between the haploid nuclei. Actin was visualised as actin patches situated at the sites of cell wall synthesis, i.e., at growth poles and at the equatorial plane, which also showed the presence of an actin ring during cytokinesis. Actin patches accumulated at the tip of the conjugation projection during the process of mating and, in the fresh zy" . .
