Organization of the Smallest Eukaryotic Spindle
In metazoans, plants, and fungi, the spindle checkpoint delays mitosis until each chromosome is attached to one or more of its own kinetochore microtubules (kMTs). Some unicellular eukaryotes, however, have been reported to have fewer kMTs than chromosomes [1-5]. If this is the case, it is unclear how the spindle checkpoint could be satisfied. In the vast majority of the previous studies, mitot...

15 صفحه اولCryptic sex in the smallest eukaryotic marine green alga.
Ostreococcus spp. are common worldwide oceanic picoeukaryotic pelagic algae. The complete genomes of three strains from different ecological niches revealed them to represent biologically distinct species despite their identical cellular morphologies (cryptic species). Their tiny genomes (13 Mb), with approximately 20 chromosomes, are colinear and densely packed with coding sequences, but no se...

15 صفحه اولOrganization of spindle microtubules in Ochromonas danica
The entire framework of microtubules (MTs) in the mitotic apparatus of Ochromonas danica is reconstructed (except at the spindle poles) from transverse serial sections. Eleven spindles were sectioned and used for numerical data, but only four were reconstructed: a metaphase, an early anaphase, a late anaphase, and telophase. Four major classes of MTs are observed: (a) free MTs (MTs not attached...
