Centromere location in Arabidopsis is unaltered by extreme divergence in CENH3 protein sequence
Genome Research, 2017 During cell division, spindle fibers attach to chromosomes at centromeres. The DNA sequence at regional centromeres is fast evolving with no conserved genetic signature for centromere identity.

Integrative genomics analysis identifies pericentromeric regions of human chromosomes affecting patterns of inter-chromosomal interactions [PDF]
arXiv, 2014 Genome-wide analysis of distributions of densities of long-range interactions of human chromosomes with each other, nucleoli, nuclear lamina, and binding sites of chromatin state regulatory proteins, CTCF and STAT1, identifies non-random highly correlated patterns of density distributions along the chromosome length for all these features.

Biological Diversity, EarlyView.This study presents a subgenome‐resolved telomere‐to‐telomere reference genome of Capsella bursa‐pastoris, named Cbp_T2T, constructed using PacBio HiFi reads, Nanopore ultra‐long reads, and Hi‐C data. Notable divergences were observed between its subgenomes, and comparative genomics identified two large inversions within the species.

Genome Biology, 2017 BackgroundParadoxically, centromeres are known both for their characteristic repeat sequences (satellite DNA) and for being epigenetically defined. Maize (Zea mays mays) is an attractive model for studying centromere positioning because many of its large

Reconstruction of the kinetochore: a prelude to meiosis
Cell Division, 2007 In eukaryotic organisms, chromosomes are spatially organized within the nucleus. Such nuclear architecture provides a physical framework for the genetic activities of chromosomes, and changes its functional organization as the cell moves through the ...

Scrambling eggs: Meiotic drive and the evolution of female recombination rates [PDF]
arXiv, 2011 Theories to explain the prevalence of sex and recombination have long been a central theme of evolutionary biology. Yet despite decades of attention dedicated to the evolution of sex and recombination, the widespread pattern of sex-differences in the recombination rate is not well understood and has received relatively little theoretical attention ...

G3: Genes, Genomes, Genetics, 2018 Crossover recombination during meiosis is accompanied by a dramatic chromosome reorganization. In Saccharomyces cerevisiae, the onset of meiotic recombination by the Spo11 transesterase leads to stable pairwise associations between previously ...

Centromere evolution and CpG methylation during vertebrate speciation
Nature Communications, 2017 Centromeres and large-scale structural variants evolve and contribute to genome diversity during vertebrate speciation. Here, we perform de novo long-read genome assembly of three inbred medaka strains that are derived from geographically isolated ...

HN1 expression contributes to mitotic fidelity through Aurora A‐PLK1‐Eg5 axis
Cytoskeleton, EarlyView.Abstract Hematological and neurological expressed 1 (HN1) is homolog of Jupiter protein from Drosophila melanogaster where it functions as a microtubule‐associated protein. However, in mammalian cells, HN1 is associated partially with y‐tubulin in centrosomes, Stathmin for stabilizing microtubules, and Cdh1 for regulating Cyclin B1 for cell cycle ...

Insect Molecular Biology, Volume 32, Issue 1, Page 56-68, February 2023., 2023 The introgression of a synthetic sex ratio distortion transgene into two different genetic backgrounds of Anopheles coluzzii by six backcrosses. We showed that the phenotype of the sex ratio distorter is stabile in the introgressed An. coluzzii strains.
