Abstract: Abstract Centromeres are epigenetically specified by the histone H3 variant CENP-A and typically associated with highly repetitive satellite DNA. We previously discovered natural satellite-free neocentromeres in Equus caballus and Equus asinus. Here, through ChIP-seq with… read more here.

DOI: 10.1105/tpc.19.00557
Abstract: Frequent centromere repositioning is the key mechanism differentiating homoeologous chromosomes in Arabideae genomes in the absence of gross chromosomal rearrangements. Centromere position may change despite conserved chromosomal collinearity. Centromere repositioning and evolutionary new centromeres (ENCs)… read more here.
