Abstract
For many years, inversions have been proposed to be a direct driving force in speciation since they suppress recombination when heterozygous. Inversions are the most common large-scale differences among humans and great apes. Nevertheless, they represent large events easily distinguishable by classical cytogenetics, whose resolution, however, is limited. Here, we performed a genome-wide comparison between human, great ape, and macaque genomes using the net alignments for the most recent releases of genome assemblies. We identified a total of 156 putative inversions, between 103 kb and 91 Mb, corresponding to 136 human loci. Combining literature, sequence, and experimental analyses, we analyzed 109 of these loci and found 67 regions inverted in one or multiple primates, including 28 newly identified inversions. These events overlap with 81 human genes at their breakpoints, and seven correspond to sites of recurrent rearrangements associated with human disease. This work doubles the number of validated primate inversions larger than 100 kb, beyond what was previously documented. We identified 74 sites of errors, where the sequence has been assembled in the wrong orientation, in the reference genomes analyzed. Our data serve two purposes: First, we generated a map of evolutionary inversions in these genomes representing a resource for interrogating differences among these species at a functional level; second, we provide a list of misassembled regions in these primate genomes, involving over 300 Mb of DNA and 1978 human genes. Accurately annotating these regions in the genome references has immediate applications for evolutionary and biomedical studies on primates.

Abstract
Structural variation has played an important role in the evolutionary restructuring of human and great ape genomes. Recent analyses have suggested that the genomes of chimpanzee and human have been particularly enriched for this form of genetic variation. Here, we set out to assess the extent of structural variation in the gorilla lineage by generating 10-fold genomic sequence coverage from a western lowland gorilla and integrating these data into a physical and cytogenetic framework of structural variation. We discovered and validated over 7665 structural changes within the gorilla lineage, including sequence resolution of inversions, deletions, duplications, and mobile element insertions. A comparison with human and other ape genomes shows that the gorilla genome has been subjected to the highest rate of segmental duplication. We show that both the gorilla and chimpanzee genomes have experienced independent yet convergent patterns of structural mutation that have not occurred in humans, including the formation of subtelomeric heterochromatic caps, the hyperexpansion of segmental duplications, and bursts of retroviral integrations. Our analysis suggests that the chimpanzee and gorilla genomes are structurally more derived than either orangutan or human genomes.

Abstract
BACKGROUND The autosomal dominant polycystic kidney disease (ADPKD) is mostly caused by mutations in the PKD1 (polycystic kidney disease 1) gene located in 16p13.3. Moreover, there are six pseudogenes of PKD1 that are located proximal to the master gene in 16p13.1. In contrast, no pseudogene could be detected in the mouse genome, only a single copy gene on chromosome 17. The question arises how the human situation originated phylogenetically. To address this question we applied comparative FISH-mapping of a human PKD1-containing genomic BAC clone and a PKD1-cDNA clone to chromosomes of a variety of primate species and the dog as a non-primate outgroup species. RESULTS Comparative FISH with the PKD1-cDNA clone clearly shows that in all primate species studied distinct single signals map in subtelomeric chromosomal positions orthologous to the short arm of human chromosome 16 harbouring the master PKD1 gene. Only in human and African great apes, but not in orangutan, FISH with both BAC and cDNA clones reveals additional signal clusters located proximal of and clearly separated from the PKD1 master genes indicating the chromosomal position of PKD1 pseudogenes in 16p of these species, respectively. Indeed, this is in accordance with sequencing data in human, chimpanzee and orangutan. Apart from the master PKD1 gene, six pseudogenes are identified in both, human and chimpanzee, while only a single-copy gene is present in the whole-genome sequence of orangutan. The phylogenetic reconstruction of the PKD1-tree reveals that all human pseudogenes are closely related to the human PKD1 gene, and all chimpanzee pseudogenes are closely related to the chimpanzee PKD1 gene. However, our statistical analyses provide strong indication that gene conversion events may have occurred within the PKD1 family members of human and chimpanzee, respectively. CONCLUSION PKD1 must have undergone amplification very recently in hominid evolution. Duplicative transposition of the PKD1 gene and further amplification and evolution of the PKD1 pseudogenes may have arisen in a common ancestor of Homo, Pan and Gorilla approximately 8 MYA. Reticulate evolutionary processes such as gene conversion and non-allelic homologous recombination (NAHR) may have resulted in concerted evolution of PKD1 family members in human and chimpanzee and, thus, simulate an independent evolution of the PKD1 pseudogenes from their master PKD1 genes in human and chimpanzee.

Abstract
In 1992 the Japanese macaque was the first species for which the homology of the entire karyotype was established by cross-species chromosome painting. Today, there are chromosome painting data on more than 50 species of primates. Although chromosome painting is a rapid and economical method for tracking translocations, it has limited utility for revealing intrachromosomal rearrangements. Fortunately, the use of BAC-FISH in the last few years has allowed remarkable progress in determining marker order along primate chromosomes and there are now marker order data on an array of primate species for a good number of chromosomes. These data reveal inversions, but also show that centromeres of many orthologous chromosomes are embedded in different genomic contexts. Even if the mechanisms of neocentromere formation and progression are just beginning to be understood, it is clear that these phenomena had a significant impact on shaping the primate genome and are fundamental to our understanding of genome evolution. In this report we complete and integrate the dataset of BAC-FISH marker order for human syntenies 1, 2, 4, 5, 8, 12, 17, 18, 19, 21, 22 and the X. These results allowed us to develop hypotheses about the content, marker order and centromere position in ancestral karyotypes at five major branching points on the primate evolutionary tree: ancestral primate, ancestral anthropoid, ancestral platyrrhine, ancestral catarrhine and ancestral hominoid. Current models suggest that between-species structural rearrangements are often intimately related to speciation. Comparative primate cytogenetics has become an important tool for elucidating the phylogeny and the taxonomy of primates. It has become increasingly apparent that molecular cytogenetic data in the future can be fruitfully combined with whole-genome assemblies to advance our understanding of primate genome evolution as well as the mechanisms and processes that have led to the origin of the human genome.

Abstract
Analyses of chromosomal rearrangements that have occurred during the evolution of the hominoids can reveal much about the mutational mechanisms underlying primate chromosome evolution. We characterized the breakpoints of the pericentric inversion of chimpanzee chromosome 18 (PTR XVI), which is homologous to human chromosome 16 (HSA 16). A conserved 23-kb inverted repeat composed of satellites, LINE and Alu elements was identified near the breakpoints and could have mediated the inversion by bringing the chromosomal arms into close proximity with each other, thereby facilitating intrachromosomal recombination. The exact positions of the breakpoints may then have been determined by local DNA sequence homologies between the inversion breakpoints, including a 22-base pair direct repeat. The similarly located pericentric inversion of gorilla (GGO) chromosome XVI, was studied by FISH and PCR analysis. The p- and q-arm breakpoints of the inversions in PTR XVI and GGO XVI were found to occur at slightly different locations, consistent with their independent origin. Further, FISH studies of the homologous chromosomal regions in macaque and orangutan revealed that the region represented by HSA BAC RP11-696P19, which spans the inversion breakpoint on HSA 16q11-12, was derived from the ancestral primate chromosome homologous to HSA 1. After the divergence of orangutan from the other great apes approximately 12 million years ago (Mya), a duplication of the corresponding region occurred followed by its interchromosomal transposition to the ancestral chromosome 16q. Thus, the most parsimonious interpretation is that the gorilla and chimpanzee homologs exhibit similar but nonidentical derived pericentric inversions, whereas HSA 16 represents the ancestral form among hominoids.

Abstract
For the last 15 years molecular cytogenetic techniques have been extensively used to study primate evolution. Molecular probes were helpful to distinguish mammalian chromosomes and chromosome segments on the basis of their DNA content rather than solely on morphological features such as banding patterns. Various landmark rearrangements have been identified for most of the nodes in primate phylogeny while chromosome banding still provides helpful reference maps. Fluorescence in situ hybridization (FISH) techniques were used with probes of different complexity including chromosome painting probes, probes derived from chromosome sub-regions and in the size of a single gene. Since more recently, in silico techniques have been applied to trace down evolutionarily derived chromosome rearrangements by searching the human and mouse genome sequence databases. More detailed breakpoint analyses of chromosome rearrangements that occurred during higher primate evolution also gave some insights into the molecular changes in chromosome rearrangements that occurred in evolution. Hardly any "fusion genes" as known from chromosome rearrangements in cancer cells or dramatic "position effects" of genes transferred to new sites in primate genomes have been reported yet. Most breakpoint regions have been identified within gene poor areas rich in repetitive elements and/or low copy repeats (segmental duplications). The progress in various molecular and molecular-cytogenetic approaches including the recently launched chimpanzee genome project suggests that these new tools will have a significant impact on the further understanding of human genome evolution.

Abstract
Using paired-end sequences from bacterial artificial chromosomes, we have constructed high-resolution synteny and rearrangement breakpoint maps among human, mouse, and rat genomes. Among the >300 syntenic blocks identified are segments of over 40 Mb without any detected interspecies rearrangements, as well as regions with frequently broken synteny and extensive rearrangements. As closely related species, mouse and rat share the majority of the breakpoints and often have the same types of rearrangements when compared with the human genome. However, the breakpoints not shared between them indicate that mouse rearrangements are more often interchromosomal, whereas intrachromosomal rearrangements are more prominent in rat. Centromeres may have played a significant role in reorganizing a number of chromosomes in all three species. The comparison of the three species indicates that genome rearrangements follow a path that accommodates a delicate balance between maintaining a basic structure underlying all mammalian species and permitting variations that are necessary for speciation.
