    • Kinetochores distinguish GTP from GDP forms of the microtubule lattice
    • of outstanding interest. There is a preference of in vitro reconstituted S. cerevisiae kinetochores for binding to GMPCPP/microtubules rather than GDP/microtubules, which provides a possible explanation for end-binding of kinetochores to the putative GTP/tubulin-capped spindle fibers. The in vitro binding is also predominantly to the plus ends of microtubules, reflecting the situation in vivo.

The structure of Candida glabrata centromeric DNA is very similar in sequence and size to that of S. cerevisiae, with conserved CDE I and III sequences separated by an AT-rich CDE II.

    • The centromere enhancer mediates centromere activation in Schizosaccharomyces pombe
    • of outstanding interest. Two important points regarding centromere function in S. pombe emerge from this work. The first is that the centromere enhancer region of the K type repeat is not absolutely essential for centromere function but is needed for immediate centromere activation when the centromeric central core is introduced via transformation on a minichromosome into an S. pombe host. This immediate activation is probably a consequence of the centromeric DNA assuming the proper chromatin conformation for kinetochore formation. The second point is that two entirely different DNA sequences derived from two native centromeres can display centromere function in S. pombe. Thus, there is no 'magic' sequence required for a functional S. pombe centromere.

A detailed analysis of centromeric DNA carried on the Drosophila minichromosome Dp1187 reveals that most of the region is composed of simple satellite sequences interspersed with single copies of six types of transposable elements. Neither the satellite sequences nor the transposable elements are localized specifically to the centromere, and it appears that these elements are not present at all Drosophila centromeres. Thus, analogous to the S. pombe system, there is no single specific DNA sequence required for centromere function in Drosophila.

Neither the satellite sequences nor the transposable elements are localized specifically to the centromere, and it appears that these elements are not present at all Drosophila centromeres. Thus, analogous to the S. pombe system, there is no single specific DNA sequence required for centromere function in Drosophila.

    • Identification of Trans-acting genes necessary for centromere function in Drosophila melanogaster
    • of outstanding interest. A genetic system based on the Drosophila Dp1187 minichromosome is used to show that mutations in genes that affect chromosome transmission (ncd, klp3A) also affect minichromosome derivatives with partially defective centromeres. Increased dosage of the nod kinesin-like protein gene also affects minichromosome inheritance. Thus, dominant genetic interactions between mutationally altered alleles and centromere-compromised minichromosomes might be used to target other genes important in centromere function in Drosophila.

    • Conservation of the centromere/kinetochore protein ZW10
    • of special interest. The product of the essential Drosophila ZW10 gene probably acts at anaphase as part of a kinetochore-associated tension-sensing checkpoint. DmZW10 is localized to the centromere/kinetochore at prometaphase, to microtubules at metaphase, and again to the kinetochore/centromere at anaphase. This study shows that DmZW10-related proteins are present in a variety of species from plants to humans and play roles in chromosomes segregation in humans and C. elegans.

    • Neocentromere activity of structurally acentric minichromosomes
    • of special interest. Stable acentric derivatives of the Drosophila minichromosome Dp1187 bind the centromere protein ZW10 and associate with spindle poles at anaphase. Evidence strongly suggests that non-centromeric sequences on the acentric derivatives have acquired partial centromere function, perhaps mediated by their previous location near a functional centromere.

    • The product of proliferation disrupter is concentrated at centromeres and required for mitotic chromosome condensation and cell proliferation
    • of special interest. The product of the Drosophila proliferation disrupter (prod) gene is localized at Chromosome 2 and 3 centromeres and a number of euchromatic sites. Cells with homozygous null prod mutations have undercondensed chromosomes and fail to undergo metaphase/anaphase transition. It is postulated that improper centromere chromatin organization interferes with kinetochore assembly and function in the mutants.

    • Centromere position in budding yeast: Evidence for anaphase A
    • of special interest. As a result of their overall simplicity, it has been postulated that S. cerevisiae cells may lack the intricacies of chromosome movement that are evident in higher eukaryotic cells. This study uses fluorescence in situ hybridization at centromeric regions to demonstrate that yeast centromeres move in a cell-cycle-dependent manner similar to that seen in complex systems. Evidence for anaphase A-like movement is also provided, on the basis of changes in centromere position relative to the spindle poles.

    • Mitosis in living budding yeast: Anaphase A but no metaphase plate
    • of special interest. A fusion of green fluorescent protein (GFP) to Lac repressor, targeted to multiple Lac operator sequences integrated into the chromosome, and a GFP fusion to alpha tubulin have enabled the visualization in living yeast cells of chromosome and spindle dynamics. This powerful technology - applied to a system where chromosomes are not visible by conventional microscopy - has so far shown that whereas S. cerevisiae chromosomes do not align at a metaphase plate, they do exhibit anaphase A movement. Often anaphase is initiated when the centromeres are closer to one spindle pole than the other, and centromeres separate before telomeres. The ability to visualize these events in living yeast cells, combined with the sophisticated genetics available with this system, should greatly facilitate the study of chromosome movement in eukaryotes.
