Supplementary Material for: A Non-Human Primate BAC Resource to Study Interchromosomal Segmental Duplications S.Kirsch C.Hodler W.Schempp 2017 <p>Segmental duplications (SDs) are involved in the reshaping and evolutionary development of primate genome architecture. Their intrinsic property to promote genomic instability facilitates genome rearrangements, thereby contributing to karyotype diversity in primates. However, comparative analyses of SDs based on whole-genome shotgun assemblies of primate genomes may lead to a distorted view of their evolutionary dynamics as this method will incorrectly assemble or simply not represent these regions. Therefore high-quality sequences of chromosomally assigned SDs are indispensable for unraveling the amplification and dispersal pattern of SDs during primate evolution. Here, we use an updated version of the ancestral duplicon state of the non-palindromic SDs of all 4 human Y-chromosome euchromatin/heterochromatin transition regions to perform a survey of duplicons genome-wide across 7 primate species. By adjusting experimental conditions to the mean nucleotide sequence divergence to human we identified 11,075 BAC clones carrying primate orthologs or paralogs of human Y chromosome-derived duplicons. Preliminary results indicate lineage-specific amplification of duplicons in prosimians and gibbons. This BAC-based framework represents the first complete set of a defined number of duplicons over 60 million years of primate evolution. Comparative sequence analysis of this genetic resource can contribute to our deeper understanding of the impact of segmental duplications on primate genome evolution.</p>
