Modern sugarcane cultivars (2n = 100-130) are complex polyploids derived from interspecific hybridization between S. officinarum and S. spontaneum, with unequal contributions of the parental genomes. In plants, the typical centromeres are often associated with heterochromatic regions consisting of large arr…
