15 صفحه اولBdelloid rotifers revisited.
S exual reproduction is one of the most striking features of the biological world. The great majority of the animals and plants with which we are most familiar reproduce at least part of the time by means of sexual reproduction with meiosis, recombination, and fertilization. But many eukaryotes reproduce asexually part of the time, and some are exclusively asexual (1, 2). Two articles in a rece...
متن کاملRotifers ingest Giardia cysts.
Seven species of rotifers representing 6 genera, Epiphanes, Plationus, Asplanchna, Philodina species A, Philodina species B. Platyias, and Brachionus, were exposed to Giardia cysts isolated from the feces of experimentally infected holstein calves. Giardia cysts were prestained with a fluorescein isothiocyanate-conjugated monoclonal antibody and mixed with viable rotifers on 3-well Teflon-coate...
متن کاملEvidence for meiotic sex in bdelloid rotifers
In their study of genetic exchange in the bdelloid rotifer Adineta vaga, Debortoli et al. [1] conclude that the patchwork pattern of allele sharing among three individuals in the genomic regions they examined is "…unlikely to arise in cases of PTH (Oenothera-like) meiosis since haplotypes are transferred as entire blocks…" and therefore that "Genetic exchange among bdelloid rotifers is more lik...
متن کاملAge Variations in Cortical Membranes of Rotifers
Electron micrographs were made of rotifers of known ages embedded in Vestopal and stained with lead hydroxide. In epithelial cells lining the gut of the rotifer, anatomical continuity is seen between the cell membrane, the cortical membranes, and the rough endoplasmic reticulum at the basal region of the cells. At their luminal surface, these cells possess a terminal web, and colloidal gold is ...
