PG - 767-79 LID - 10.1007/s10577-015-9495-3 [doi] AB - Centromere sequences exist as gaps in many genome assemblies due to their repetitive nature. Here we take an unbiased approach utilizing centromere protein A (CENP-A) chomatin immunoprecipitation followed by high-throughput sequencing to identify the centromeric repeat sequence in the threespine stickleback fish (Gasterosteus aculeatus). A 186-bp, AT-rich repeat was validated as centromeric using both fluorescence in situ hybridization (FISH) and immunofluorescence combined with FISH (IF-FISH) on interphase nuclei and metaphase spreads. This repeat hybridizes strongly to the centromere on all chromosomes, with the exception of weak hybridization to the Y chromosome. Together, our work provides the first validated sequence information for the threespine stickleback centromere.
