Chromosomal Differentiation of (Poaceae) Based on Four Satellite DNA Families.

Diverse families of satellite DNA (satDNA) were detected in heterochromatin regions of . This kind of repetitive DNA consists of tandem repeat sequences forming big arrays in genomes, and can contribute to lineages differentiation. The differentiation between types of satDNA is related to their sequence identity, the size and number of monomers forming the array, and their chromosomal location.
