Centromeric retroelements and satellites interact with maize kinetochore protein CENH3.
Maize centromeres are composed of CentC tandem repeat arrays, centromeric retrotransposons (CRs), and a variety of other repeats. One particularly well-conserved CR element, CRM, occurs primarily as complete and uninterrupted elements and is interspersed thoroughly with CentC at the light microscopic level. To determine if these major centromeric DNAs are part of the functional centromere/kinet...
متن کاملGenome-wide characterization of centromeric satellites from multiple mammalian genomes.
Despite its importance in cell biology and evolution, the centromere has remained the final frontier in genome assembly and annotation due to its complex repeat structure. However, isolation and characterization of the centromeric repeats from newly sequenced species are necessary for a complete understanding of genome evolution and function. In recent years, various genomes have been sequenced...
متن کاملSimple and Complex Centromeric Satellites in Drosophila Sibling Species
Centromeres are the chromosomal sites of assembly for kinetochores, the protein complexes that attach to spindle fibers and mediate separation of chromosomes to daughter cells in mitosis and meiosis. In most multicellular organisms, centromeres comprise a single specific family of tandem repeats-often 100-400 bp in length-found on every chromosome, typically in one location within heterochromat...
متن کاملNucleosomes and centromeric DNA packaging.
The eukaryotic chromosome is a conserved structure, with the DNA double-helix wrapping around octamers of histone proteins to form the chromatin, which is further packaged into chromosomes. The centromere defines the kinetochore, the region of spindle microtubule attachment that pulls the two replicated chromatids of each chromosome apart during cell division (Fig. 1), leading to fidelity in tr...
متن کاملStrand-biased DNA methylation associated with centromeric regions in Arabidopsis.
The Arabidopsis genome project assembled 15 megabases of heterochromatic sequence, facilitating investigations of heterochromatin assembly, maintenance, and structure. In many species, large quantities of methylcytosine decorate heterochromatin; these modifications are typically maintained by methyltransferases that recognize newly replicated hemimethylated DNA. We assessed the extent and patte...
