Abstract
Tandemly repeated, non-coding satellite DNAs are among the most rapidly evolving genetic elements in eukaryotic genomes, changing in identity, copy number, and genomic distribution. A growing list of empirical studies suggests that this rapid evolution has profound consequences on core biological processes. Here, we review recent studies that investigate the satellite DNA-mediated biology revealed by generating either inter-species hybrids or genotypes expressing divergent, satellite DNA-interacting proteins from a closely related species. The genetic incompatibilities that arise implicate chromosome segregation, DNA repair, the establishment of silent heterochromatin, and the spatial organization of chromosomes as essential processes vulnerable to the rapid evolution of satellite DNA. We discuss emergent themes from this relatively young body of literature and future challenges for the field.

dosage compensation, sex determination, chromosome remodeling);
· Architectural/epigenomic organization of the genome;
· Functional annotation of the genome;
· Functional and comparative genomics in plants and animals;
· Karyology studies that help resolve difficult taxonomic problems or that provide
clues to fundamental mechanisms of genome and karyotype evolution in plants and animals;
