Rice centromere 8 was previously proposed to be an "immature" centromere that recently arose from a genic region. Our comparative genomics analysis indicates that Cen8 was formed at its current location at least 7-9 million years ago and was physically shifted by a more recent inversion of a segment spanning centromeric and pericentromeric regions.
