The centromere of the maize (Zea mays) B chromosome contains several megabases of a B-
specific repeat (ZmBs), a 156-bp satellite repeat (CentC), and centromere-specific …

The maize (Zea mays) B centromere is composed of B centromere–specific repeats (ZmBs),
centromere-specific satellite repeats (CentC), and centromeric retrotransposons of maize …

Supernumerary or B chromosomes are selfish entities that maintain themselves in
populations by accumulation mechanisms. The accumulation mechanism of the B …

Centromeres are determined by poorly understood epigenetic mechanisms. Centromeres
can be activated or inactivated without changing the underlying DNA sequences. However …

Centromeric DNA sequences in multicellular eukaryotes are often highly repetitive and are
not unique to a specific centromere or to centromeres at all. Thus, it is a major challenge to …

Maize chromosome spreads containing the supernumerary B chromosome were hybridized
with probes from various repetitive elements including CentC, CRM, and CentA, which have …

Previous work has identified sequences specific to the B chromosome that are a major
component of the B centromere. To address the issue of the origin of the B and the evolution …

Stable maize (Zea mays) chromosomes were recovered from an unstable dicentric
containing large and small versions of the B chromosome centromere. In the stable …

We describe a comprehensive and general approach for mapping centromeres and present
a detailed characterization of two maize centromeres. Centromeres are difficult to map and …

The ability of centromeres to alternate between active and inactive states indicates
significant epigenetic aspects controlling centromere assembly and function. In maize (Zea …
