Ultrastructure of Mitosis and Spindle Pole Bodies in the Zygomycetous Fungus Coemansia reversa Using Conventional Fixation and Freeze Substitution
نویسندگان
چکیده
The purpose of the Assembling the Fungal Tree of Life project (AFTOL) is to better understand the evolutionary history of the Kingdom Fungi using multiple data types, including molecular sequences and ultrastructural characters [1]. Microscopic features such as nuclear division and associated organelles, e.g., spindle pole bodies (SPB), are informative for revealing relationships between many taxonomic groups.

Evolution of zygomycetous spindle pole bodies: Evidence from Coemansia reversa mitosis.
PREMISE OF THE STUDY The earliest eukaryotes were likely flagellates with a centriole that nucleates the centrosome, the microtubule-organizing center (MTOC) for nuclear division. The MTOC in higher fungi, which lack flagella, is the spindle pole body (SPB). Can we detect stages in centrosome evolution leading to the diversity of SPB forms observed in terrestrial fungi? Zygomycetous fungi, whic...
متن کاملMitosis in the fission yeast Schizosaccharomyces pombe as revealed by freeze-substitution electron microscopy.
Nuclear division in Schizosaccharomyces pombe has been studied in transmission electron micrographs of sections of cells fixed by a method of freeze-substitution. We have found cytoplasmic microtubules in the vicinity of the spindle pole bodies and two kinds of microtubules, short discontinuous ones and long, parallel ones in the intranuclear mitotic spindle. For most of the time taken by nucle...
متن کاملUltrastructure of mitosis in the cowpea rust fungus Uromyces phaseoli var. Vignae
Aspects of the ultrastructure of mitotic nuclei of the fungus Uromyces phaseoli var. vignae are described from both intercellular hyphae in the cowpea host and infection structures induced to differentiate in vitro. The interphase nucleus-associated organelle (NAO) consists of two trilamellar acircular disks connceted by an osmiophilic bar. The intranuclear spindle develops between these disks ...
متن کاملA novel mechanism of nuclear envelope break-down in a fungus: nuclear migration strips off the envelope.
In animals, the nuclear envelope disassembles in mitosis, while budding and fission yeast form an intranuclear spindle. Ultrastructural data indicate that basidiomycetes, such as the pathogen Ustilago maydis, undergo an 'open mitosis'. Here we describe the mechanism of nuclear envelope break-down in U. maydis. In interphase, the nucleus resides in the mother cell and the spindle pole body is in...
متن کاملUltrastructure of Kurloff body proteoglycans after high pressure freezing, cryosubstitution and postembedding staining with cuprolinic blue.
Very high pressure freezing and cryosubstitution of Kurloff cells preserves the ultrastructural morphology of Kurloff bodies, particularly the myelin figures, as shown by embedding in epoxy resin and conventional postembedding staining. It also preserves the Kurloff body proteoglycans as more expanded spindle-like shapes than does fixation with formaldehyde at atmospheric pressure. But, proteog...
