Rice (Oryza sativa L.) centromeres are composed of 155-bp satellite repeats (CentO), centromere-specific retrotransposon (CRR), and a variety of other repeats. Previous studies have shown that CentO and CRR elements are both parts of the functional centromere/kinetochore complex. In this study, a naturally occurring karyotype rearrangement involving a reciprocal translocation between chromosomes 9 and 11 in an indica rice Zhongxian 3037 has been identified. The recombinant centromere in Chr11L·9L has two CentO tandem arrays, separated by a long array of 5S rDNAs. Chromatin immunoprecipitation and immunostaining showed that centromere-specific histone H3 (cenH3) variant was bound to the two flanking CentO arrays, but not to the 5S rDNAs residing between the CentO repeats. No obvious difference was detected in H3K4me2 and H3K9ac modification of the 5S rDNAs between the wild type and the mutant. Therefore, the translocation results in a recombinant stable chromosome with interrupted centromeric domains. A lack of cenH3 binding in 5S rDNA sequences residing within the centromeric core suggests that not all centromeric sequences confer centromere identity in rice.
