Internally tagged, functional Cse4/CENP-A/CenH3 histone variant is exclusively centromeric and stable through the budding yeast cell cycle after replacement in S phase.
A non-coding RNA-based targeting mechanism could potentially epigenetically maintain specialized chromatin structures, such as the centromere, in vivo.

The sensitivity of Arabidopsis meiotic centromeres to heat stress suggests that centromere function is one of the key determinants of plant reproduction under rising temperatures.

Direct live-cell imaging of human cells, combined with RNA-seq, qPCR and in vitro reconstitution essays, reveal that mitotic progression, arrest, exit or death is independent of de novo transcription.

Centromeric protein M (CENP-M) is required for the stabilization of a quaternary complex that plays a crucial role in kinetochore organization and function.
Centromere deletion in Cryptococcus deuterogattii results in neocentromeres, which span actively expressed genes and at elevated temperatures cen10∆ mutants are unstable leading to chromosome fusion and silencing of the neocentromere.
Centromeric histones, the foundation for accurate chromosome segregation, have now been re-engineered to allow for analysis of the stoichiometry of required domains.

CenH3, the defining component of centromeres in almost all eukaryotes, was independently lost in four insect lineages that transitioned from monocentricity to holocentricity.
