The centromeres in most model eukaryotes are composed of highly repetitive DNA sequences.We have recently demonstrated that several rice centromeres are composed of complex DNA,including both centromere-specific retrotransposons (CRR elements) and satellite repeats (CentO satellite),as well as single copy sequences.Active genes were found in the functional domains of the centromeres of rice chromosomes 3 and 8.These active genes are expressed in several rice tissues and display histone modification patterns similar to those located in rice euchromatin.
