Abstract
Guenons (tribe Cercopithecini) are the most widely distributed nonhuman primate in the tropical forest belt of Africa and show considerable phenotypic, taxonomic, and ecological diversity. However, genomic information for most species within this group is still lacking. Here, we present a high-quality de novo genome (total 2.90 Gb, contig N50 equal to 22.7 Mb) of the mona monkey (Cercopithecus mona), together with genome resequencing data of 13 individuals sampled across Nigeria. Our results showed differentiation between populations from East and West of the Niger River ∼84 ka and potential ancient introgression in the East population from other mona group species. The PTPRK, FRAS1, BNC2, and EDN3 genes related to pigmentation displayed signals of introgression in the East population. Genomic scans suggest that immunity genes such as AKT3 and IL13 (possibly involved in simian immunodeficiency virus defense), and G6PD, a gene involved in malaria resistance, are under positive natural selection. Our study gives insights into differentiation, natural selection, and introgression in guenons.

Abstract
Haematological and serum biochemical values are useful guides and biomarkers in health and diseases for reaching a diagnosis, estimating disease prognosis and monitoring treatment progress, in mammals. Reference ranges for some parameters differ among species of mammals and between sexes within a species. There is dearth of information on standard reference value for blood parameters for Nigerian indigenous monkeys. Whole blood and serum samples obtained from 50 apparently healthy adult monkeys in both captivity and from the wild in southwest Nigeria were subjected to haematology and serum biochemistry to obtain preliminary reference values for haematological and serum biochemical analytes for Cercocebus sebaeus (Green monkey), Cercopithecus mona (Mona monkey), Erythrocebus patas (Patas monkey) and Papio anubis (Anubis baboon). Numerical data were summarized as mean and standard deviation and subjected to statistical analysis; Student t test and analysis of variance, to compare values of blood parameters obtained between species and gender. A p-value less than 0.05 was considered significant. The hematocrit of male animals were significantly higher than that of females (P=0.01) in all the 4 species studied but there was no significant difference in other blood parameters such as total white blood cell and the differential counts, platelet count, serum aspartate transferase, alanine transferase, alkaline phosphatase, total plasma protein, albumin, and globulin concentrations between the sexes. Generally, there was no significant difference between total white blood cell and the differential counts, hematocrit, red cell count, haemoglobin concentration, platelet count, serum aspartate transferase, alanine transferase, alkaline phosphatase, total plasma protein, albumin, and globulin concentrations among the monkey species.

Abstract
Alpha satellite is the major repeated DNA element of primate centromeres. Specific evolutionary mechanisms have led to a great diversity of sequence families with peculiar genomic organization and distribution, which have till now been studied mostly in great apes. Using high throughput sequencing of alpha satellite monomers obtained by enzymatic digestion followed by computational and cytogenetic analysis, we compare here the diversity and genomic distribution of alpha satellite DNA in two related Old World monkey species, Cercopithecus pogonias and Cercopithecus solatus, which are known to have diverged about 7 Ma. Two main families of monomers, called C1 and C2, are found in both species. A detailed analysis of our data sets revealed the existence of numerous subfamilies within the centromeric C1 family. Although the most abundant subfamily is conserved between both species, our fluorescence in situ hybridization (FISH) experiments clearly show that some subfamilies are specific for each species and that their distribution is restricted to a subset of chromosomes, thereby pointing to the existence of recurrent amplification/homogenization events. The pericentromeric C2 family is very abundant on the short arm of all acrocentric chromosomes in both species, pointing to specific mechanisms that lead to this distribution. Results obtained using two different restriction enzymes are fully consistent with a predominant monomeric organization of alpha satellite DNA that coexists with higher order organization patterns in the C. pogonias genome. Our study suggests a high dynamics of alpha satellite DNA in Cercopithecini, with recurrent apparition of new sequence variants and interchromosomal sequence transfer.

Abstract
The samango monkey is South Africa's only exclusively forest dwelling primate and represents the southernmost extent of the range of arboreal guenons in Africa. The main threats to South Africa's forests and thus to the samango are linked to increasing land-use pressure and increasing demands for forest resources, resulting in deforestation, degradation and further fragmentation of irreplaceable habitats. The species belongs to the highly polytypic Cercopithecus nictitans group which is sometimes divided into two species C. mitis and C. albogularis. The number of subspecies of C. albogularis is also under debate and is based only on differences in pelage colouration and thus far no genetic research has been undertaken on South African samango monkey populations. In this study we aim to further clarify the number of samango monkey subspecies, as well as their respective distributions in South Africa by combining molecular, morphometric and pelage data. Overall, our study provides the most comprehensive view to date into the taxonomic description of samango monkeys in South Africa. Our data supports the identification of three distinct genetic entities namely; C. a. labiatus, C. a. erythrarchus and C. a. schwarzi and argues for separate conservation management of the distinct genetic entities defined by this study.

Abstract
A study group of Campbell's monkeys (Cercopithecus c. campbelli) provided data on affiliative and agonistic relationships between females. Over a period of two years (involving 111 hr), we conducted observations of a captive group which had a composition similar to wild groups. We were able to identify a monitor-adjust social system with frequent affiliative interactions, directed gazing and avoidances rather than aggressive acts. We described long-term differentiated affiliative bonds: adult females interacting more often with some group mates than others, especially if they were relatives. Interactions between matrilines concerned essentially play and young adult females. We found a significant linear hierarchy of dominance with rare reversals and a stable intermatriline dominance. In contrast to other single-male groups, our adult male was socially integrated into the group although this may have been because of the housing conditions. Comparisons with the social organization of other captive and wild guenon groups are discussed.

Abstract
In this study, we compare the behavioral development of captive male vervet monkeys (Chlorocebus pygerythrus) and Sykes' monkeys (Cercopithecus albogularis) to male hybrids of these species. Focal animal sampling sessions were conducted on the study subjects from birth to 90 months of age. Behavioral categories (affiliative, approach, play, sexual, tension, aggressive) were plotted for each species and the hybrids; curves were fitted using polynomial regression and were evaluated with the Wilcoxon signed ranks test. With the exception of play behaviors, the male C. pygerythrus x C. albogularis hybrids modeled the Sykes' pattern of behavioral development. We suggest that this result reflects a sex-linked paternal effect.

Abstract
We report on reciprocal painting between humans and two Cercopithecini species, Erythrocebus patas (patas monkey) and Cercopithecus neglectus (De Brazza's monkey). Both human and monkeys chromosome-specific probes were made by degenerate oligonucleotide primed PCR (DOP-PCR) from flow sorted chromosomes. Metaphases of both monkey species were first hybridized with human chromosome-specific probes and then human metaphases were hybridized with chromosome paints from each monkey species. The human paint probes detected 34 homologous segments on the C. neglectus karyotype, while the C. neglectus probes, including the Y, revealed 41 homologous segments on the human karyotype. The probes specific for human chromosomes detected 29 homologous segments in the E. patas karyotype, while the patas monkey probes painted 34 segments on the human karyotype. We tested various hypotheses of Cercopithecini phylogeny and taxonomy developed by morphologists, molecular biologists and cytogeneticists. Our hybridization data confirm that fissions (both Robertsonian and non-Robertsonian) are the main mechanism driving the evolutionary trend in Cercopithecini toward higher diploid numbers and strongly suggest an early phylogenetic bifurcation in Cercopithecini. One branch leads to Cercopithecus neglectus/Cercopithecus wolfi while the other line leads to Erythrocebus patas/Chlorocebus aethiops. Allenopithecus nigroviridis may have diverged prior to this major phylogenetic node.

Abstract
Chromosomal homologies were established between human and Francois' monkey (Semnopithecus francoisi, 2n = 44) by chromosome painting with chromosome-specific DNA probes of all human chromosomes except the Y. Except for human chromosome 1, 2, 6, 16 and 19 probes which gave signals on two nonhomologous S. francoisi chromosomes respectively, all other probes each hybridized to a single chromosome. Only two S. francoisi chromosomes (No. 12 and No. 21) were each labelled by two separate probes (14 and 15, 21 and 22, respectively). In total, 23 human chromosome-specific probed detected 30 homologous chromosomes and chromosomal segments in the haploid S. francoisi genome. The results indicated a high degree of conservation of chromosomal synteny between human and this langur. Only some chromosomal rearrangements occurred in this langur. Comparison of the hybridization patterns of human painting probes on this langur with the data on other primates suggested that Asian langurs were karyotypically more closely related to each other than to African langurs.

Abstract
An apparent species-specific relatedness of SIVagm suggests a coevolution with their natural hosts. However, the exact species or subspecies classification of African green monkeys, AGM, is uncertain because current classification schemes rely on phenotype markers, while more definitive genetic data are lacking. In this study, the CD4 protein involved in tissue type recognition was genetically cloned and sequenced from PBMC RNA from all AGM species, including Barbados green monkeys (BGM). Phylogenetic trees were constructed that also included genomic CD4 nucleotide sequences from patas, sooty mangabeys, rhesus and pig-tail macaques, chimpanzees, and humans. Chimpanzees and humans consistently clustered together. Monkeys within the Cercopithecus genus formed a separate cluster which included pata monkeys, supporting its grouping as a member of Cercopithecus. Surprisingly, sooty mangabeys were genetically more closely related to Asian macaques than to other African species, which might explain why macaques are more susceptible to infection by the SIVsm group than to infection by SIVagm or HIV-1 and why patas, on the other hand, are highly susceptible to SIVagm infection. Based on CD4 genetic data, tantalus, vervets, grivets, and sabaeus formed separate subgroups with BGM grouping closely with vervets. The branching order of the AGM species was related to that of their respective SIVagm env sequences. The study suggests a strong correlation between CD4 phylogeny and the susceptibility of the host species to infection by a specific lentivirus and supports the assumption of a coevolution of SIVagm and AGM. CD4 sequencing is suggested as a relevant method for genetic determination of primate species.

Abstract
The chromosomal localization of the gene for retinoblastoma (RB1), which has been mapped to band 13q14 in man, was studied by in situ hybridization on metaphase chromosomes of selected primates, including Pithecia pithecia, Macaca sylvana, and Cercopithecus aethiops tantalus. The results allowed us to determine the position of the bands homologous to human chromosome band 13q14 in these species. Hybridization analysis corroborated the results of previous studies that defined the chromosome homologous to human chromosome 13 (HSA 13) in these species. By comparing RB1 localizations and banding patterns, it is shown that the rearrangement separating HSA 13 from its homologous chromosome in Cercopithecidae is not a pericentric inversion, as suggested by earlier studies. Since the banding pattern and RB1 localization are not changed, the modification of the centromeric index is explained by a centromeric shift or by two inversions, one pericentric and one paracentric.

Abstract
We have established a new simian-type blood group system (M blood groups) in the African green monkey (Cercopithecus aethiops), using a haemagglutinating antibody which was developed by alloimmunization. The M blood groups consisted of two phenotypes, type-M and type-m. We have also determined the mode of inheritance as well as the distribution of both simian-type M and human-type ABO blood groups, employing 113 families including 160 animals. The family analysis revealed that (1) the simian-type M blood groups were governed by the two alleles, dominant M and recessive m, and (2) the human-type ABO blood groups were governed by 3 alleles, codominant A and B and silent O, although no monkey of phenotype-O was found in our breeding colony. Differences in the phenotypic distribution and gene frequency of respective M and ABO blood groups were observed among 3 populations imported at different times. The genetic management of the African green monkey breeding colony was discussed in relation to the difference in distribution of phenotypes of M and ABO blood groups between the parental (wild-originated) and the first filial (colony-born) populations.

Abstract
A previously described segment of African green monkey DNA (cloned in phage lambda MkA) contains deca-satellite linked to DNA sequences that are estimated to occur once per genome. Sequences homologous to the low copy number sequences in lambda MkA are also associated with species-specific satellite DNAs in the human and mouse genomes. A second clone, lambda Mk8, contains a monkey DNA region that is colinear and homologous to a portion of the low copy number sequences in lambda MkA, but no satellite sequences. The two cloned segments are markedly different starting at a point proximal to the satellite DNA region in lambda MkA. DNA-blotting experiments indicate that lambda Mk8 but not lambda MkA represents the typical genomic organization and that the low copy number segments occur only once per haploid genome. The data suggest that rearrangements such as deletions or inversions occurring in monkey cells account in part for the structure of lambda MkA. Additional rearrangements may have occurred during cloning in E. coli. This unique chromosomal region may be particularly susceptible to recombination.

Abstract
We have isolated a cDNA clone coding for the simian TGF-beta precursor from a cDNA library made from an African green monkey cell line, BSC-40. The deduced amino acid sequence of the mature simian TGF-beta shows 100% homology with that of the human TGF-beta: Strong sequence homology was found between the precursor regions of the human and simian proteins with only five amino acid changes out of 278. The simian (and murine) precursor sequence was found to code for one less amino acid residue than the human. The implications of these results with respect to the isolation of a growth inhibitor from these cells functionally related to the TGF-beta molecule are discussed.

Abstract
The structure of LINE-1 (L1Ca) family members present on African green monkey chromosome CAE-19 is compared with that of the entire set of L1Ca sequences present in the monkey genome. The analysis involved annealing of cloned subsegments of monkey L1 family members to DNA-blots containing restriction endonuclease digests of either total monkey liver DNA or DNA isolated from a monkey/mouse somatic cell hybrid carrying the single monkey chromosome. In addition, L1Ca segments cloned from hybrid cell DNA were characterized by restriction endonuclease mapping and hybridization. The data indicate that, taken as a whole, the set of L1Ca sequences on CAE-19 tends to differ in characteristic ways from the set present in the total monkey genome.

Abstract
We have determined the size of arrays formed by tandemly repeated monomers of alpha DNA in African green monkey cells. DNA fragments containing intact alpha DNA arrays were generated by digestion of genomic DNA with restriction endonuclease that do not have sites in the alpha DNA consensus sequence. Their size was determined by Southern analysis and by sedimentation through neutral sucrose gradients followed by probing of each fraction for alpha sequences. The restriction fragments varied in size with the most frequent being 78 kilobase pairs long. We have also shown that they contain very little non-alpha DNA sequences. This suggests a minimum array of 450 tandemly repeated alpha DNA monomers, which is more than an order of magnitude larger than previously supposed.

Abstract
The L1 family of long interspersed nucleotide sequences (LINES) has recently been identified and characterized in the small polydisperse circular DNA (spc-DNA) populations of monkey (1), human (2) and mouse (3) cells. In monkey spc-DNA, the L1 (also known as Kpn I) family is present in discrete size classes (ranging from 300 to 6000 base pairs (bp)) which appear to be generated by non homologous recombination events within chromosomal elements. In this communication it is shown that different regions of the consensus L1 family are present at different frequencies in monkey spc-DNA (as they are in chromosomal DNA), that all regions of the family are present in extrachromosomal DNA, and that each region appears to be represented in an identical discrete spc-DNA size distribution. This size distribution reflects a non-sequence specific mechanism that generates spc-DNA size classes by chromosomal DNA recombination events that are in some way constrained to occur between sites separated by relatively defined lengths.

Abstract
The nucleotide sequence and enhancer activity of the long terminal repeats (LTRs) associated with a cloned endogenous African green monkey (AGM) retroviral DNA designated as lambda-AGM-1 was studied. A unique feature of the endogenous AGM proviral LTRs was the presence of multiple copies of two types of directly repeating units in the U3 region: 16 8-base-pair (bp) repeats were present in the 5' LTR and 12 were present in the 3' LTR which were bound by a 6-bp perfect direct repeat; tandem duplication of a 32-bp sequence resulted in 3.5 copies in the 5' LTR and 2.5 copies in the 3' LTR. Nucleotide sequence homology was seen between the 8-bp direct repeats located in the AGM proviral LTRs and a 10-bp repeat unit of the deca-satellite present in AGM cellular DNA. The 32-bp repeats of the AGM proviral LTRs contained sequences which were related to the SV40 21-bp repeats and to the "core" of the SV40 72-bp enhancer element. Furthermore, the AGM provirus was distinct from known infectious retroviruses due to the presence of a primer-binding sequence complementary to the 3' terminus of mammalian tRNAGly. Functional analysis of the 3' LTR present in lambda-AGM-1 DNA by chloramphenicol acetyltransferase assay demonstrated enhancer activity associated with the 32-bp direct repeats. Sequences outside the 32-bp unit were necessary for full activator function, suggesting the presence of multiple enhancer domains in the AGM provirus.

Abstract
The pro alpha 1 (I) collagen structural gene (COL1A1), the acid alpha-glucosidase (GAA), and the thymidine kinase (TK) genes, known to be closely linked in man (HSA) and mapped to HSA17, were found syntenic in two Cercopithecoidae species, the baboon (Papio papio, PPA) and the African green monkey (Cercopithecus aethiops, CAE) and assigned to homoeologous chromosomes, PPA16 and CAE19, respectively. The assignment of COL1A1 was obtained using two human cDNA probes. Hind III restriction sites found in man were present in the two species. The particular CAE individual used in the experiment showed a polymorphism for one DNA fragment.

Abstract
Comparison of the sequences at the ends of several newly cloned and full length members of the monkey KpnI family with one another and with previously described monkey and human segments defines the nucleotide sequence at the two termini. No terminal repeats either direct or inverted are noted within full length family members which may or may not be immediately flanked by direct repeats. At the 3' terminus, several family members have polyadenylation signals followed by a d(A)-rich stretch. The genomic frequency of segments within the full length element increases markedly from the 5' to the 3' terminus, consistent with the cloning of various truncated family members. One such truncated version joined to a low copy number DNA segment is inserted in monkey alpha-satellite where the combination appears to have been amplified in conjunction with the satellite itself.

Abstract
The karyotypes of a female and of a male Presbytis cristatus are analysed. In the latter, there is a complex Y-autosome rearrangement. The phyletic position of this species, in relation to genus Colobus, previously studied, is proposed, considering the sequence of chromosomal rearrangements which occurred during their evolution. These rearrangements, in addition to the t(Y-autosome), are characterized by a high frequency of inversions, and above all, by several non-Robertsonian translocations which occurred very rarely during evolution of other Primates.

Abstract
We have studied the structure of tandemly repetitive alpha-satellite chromatin (alpha-chromatin) in African green monkey cells (CV-1 line), using restriction endonucleases and staphylococcal nuclease as probes. While more than 80% of the 172-base-pair (bp) alpha-DNA repeats have a HindIII site, less than 15% of the alpha-DNA repeats have an EcoRI site, and most of the latter alpha-repeats are highly clustered within the CV-1 genome. EcoRI and HindIII solubilize approximately 8% and 2% of the alpha-chromatin, respectively, under the conditions used. EcoRI is thus approximately 30 times more effective than HindIII in solubilizing alpha-chromatin, with relation to the respective cutting frequencies of HindIII and EcoRI on alpha-DNA. EcoRI and HindIII solubilize largely non-overlapping subsets of alpha-chromatin. The DNA size distributions of both EcoRI- and HindIII-solubilized alpha-chromatin particles peak at alpha-monomers. These DNA size distributions are established early in digestion and remain strikingly constant throughout the digestion with either EcoRI or HindIII. Approximately one in every four of both EcoRI- and HindIII-solubilized alpha-chromatin particles is an alpha-monomer. Two-dimensional (deoxyribonucleoprotein leads to DNA) electrophoretic analysis of the EcoRI-solubilized, sucrose gradient-fractionated alpha-oligonucleosomes shows that they do not contain "hidden" EcoRI cuts. Moreover, although the EcoRI-solubilized alpha-oligonucleosomes contain one EcoRI site in every 172-bp alpha-DNA repeat, they are completely resistant to redigestion with EcoRI. This striking difference between the EcoRI-accessible EcoRI sites flanking an EcoRI-solubilized alpha-oligonucleosome and completely EcoRI-resistant internal EcoRI sites in the same alpha-oligonucleosome indicates either that the flanking EcoRI sites occur within a modified chromatin structure or that an altered nucleosome arrangement in the vicinity of a flanking EcoRI site is responsible for its location in the nuclease-sensitive internucleosomal (linker) region. Analogous redigestions of the EcoRI-solubilized alpha-oligonucleosomes with either HindIII, MboII or HaeIII (both before and after selective removal of histone H1 by an exchange onto tRNA) produce a self-consistent pattern of restriction site accessibilities. Taken together, these data strongly suggest a preferred nucleosome arrangement within the EcoRI-solubilized subset of alpha-oligonucleosomes, with the centers of most of the nucleosomal cores being approximately 20 bp and approximately 50 bp away from the nearest EcoRI and HindIII sites, respectively, within the 172-bp alpha-DNA repeat. However, as noted above, the clearly preferred pattern of nucleosome arrangement within the EcoRI-solubilized alpha-oligonucleosomes is invariably violated at the ends of every such alpha-oligonucleosomal particle, suggesting at least a partially statistical origin of this apparently non-random nucleosome arrangement.(ABSTRACT TRUNCATED AT 400 WORDS)

Abstract
We describe here the interruption of a cloned African green monkey alpha-satellite array by an 829-base-pair-long nonsatellite DNA segment. Hybridization experiments indicate that the sequences within the interruption are homologous to segments frequently found in the 6-kilobase-pair-long members of the KpnI family of long, interspersed repeats. These data confirm and extend earlier results suggesting that sequences common to the KpnI family can occur independently of one another and in segments of variable lengths. The 829-base-pair-long segment, which is termed KpnI-RET, contains a terminal stretch of adenosine residues preceded by two typical but overlapping polyadenylation sites. KpnI-RET is flanked by direct repeats of a 14-base-pair-long segment of alpha-satellite that occurs only once in the satellite consensus sequence. These structural features suggest that KpnI-RET was inserted into the satellite array as a movable element.

Abstract
A potential Z-DNA sequence, (dA-dC)9, has been found to replace the customary A-rich region in the middle of an Alu family member in the African green monkey genome. This Alu, bounded by imperfect direct repeats, also contains an unusual 3' end and may be a member of a large subfamily of such sequences.

Abstract
An electrophoretic survey of 13 serum proteins was carried out on samples drawn from 340 vervet monkeys (Cercopithecus aethiops) living in 30 troops from four different localities in central and southern Kenya. The proportion of polymorphic loci is 0.17 and the average heterozygosity is 0.05. The group specific component, prealbumin carboxylesterase, and transferrin are all polymorphic. The analysis of the patterns of gene diversity show that a large part of the genic variation exists within individual troops and among neighboring troops from the same trapping locality. Only a small proportion of the overall genetic variability occurs between the populations at the different trapping localities which are separated by between 80 and 380 km. The migration of young males from their natal troops is a likely mechanism of gene flow among the vervet populations. Gene flow appears to be sufficient to prevent high levels of geographic variation in the gene frequencies at these loci, but is insufficient to prevent the occasional fixation of alleles in some local populations.

Abstract
Fragments of African green monkey (Cercopithecus aethiops) DNA (3.5 to 18.0 kilobases) were inserted downstream from the thymidine kinase (TK, tk) coding region in pTK206/SV010, a gene construct which lacks both copies of the hexanucleotide 5'-AATAAA-3' and contains a simian virus 40 origin of replication, allowing it to replicate in Cos-1 cells. No polyadenylated tk mRNA was detected in Cos-1 cells transfected by pTK206/SV010. The ability of simian DNA fragments to restore tk gene expression was examined by measuring the incorporation of [125I]iododeoxycytidine into DNA in Cos-1 cells transfected by pTK206/SV010 insertion derivatives. tk gene expression was restored by the insertion in 56 of the 67 plasmids analyzed, and the level of expression equaled or exceeded that obtained with the wild-type tk gene in 30 of these. In all plasmids examined that showed restoration of tk gene expression, polyadenylated tk mRNA of discrete size was detected. The sizes of these tk mRNAs were consistent with the existence of processing and polyadenylation signals within the inserted DNA fragments. The frequency with which inserted fragments restored tk gene expression suggests that the minimal signal for processing and polyadenylation is a hexanucleotide (AAUAAA or a similar sequence). LTK- cells were biochemically transformed to TK+ with representative insertion constructs. pTK206/SV010 transformed LTK- cells at a very low frequency; the frequency of transformation with insertion derivatives was 40 to 12,000 times higher.

Abstract
Three different members of a family (KpnI-family) of interspersed repeated DNA sequences were found linked to alpha-satellite sequences in cloned segments of the African green monkey genome. In two of these segments the KpnI-family member is over 6 kbp in length and one of them is flanked by alpha-satellite on both sides indicating that it was inserted into a satellite array. Hybridization of subcloned portions of the family members to restriction endonuclease digests of monkey and human DNA and to a genomic library of African green monkey DNA indicate that 1) family members are interspersed in both the monkey and human genomes, 2) some family members may include sequences in addition to those in the three characterized here, 3) some family members may contain only parts of the sequences characterized here and 4) while the overall organization of the family is similar in the human and monkey genome the majority of the family members in each of the two genomes are distinctly identified by the variant position of certain restriction endonuclease sites. This last observation suggests that within each genome there is a tendency to maintain particular versions of the sequence. Observations 2) and 3) suggest that the KpnI family is complex and includes a variety of subfamilies.

Abstract
The frequencies of sister chromatid exchanges (SCE) were studied in primary kidney cell culture, diploid cell line 5018, pseudodiploid spontaneously transformed cell line 4647 and hypotetraploid cell line 455 of the African green monkey. Bromodeoxyuridine was used at a concentration of 10 micrograms/ml. The slides were stained with acridine orange and Giemsa for sister chromatid differentiation. In the first three cases, SCE were scored in 100 metaphases of each culture. The distribution of cells from the number of SCE differs from the normal law and was approximated fairly well by the lognormal distribution pattern. The geometrical means of SCE per cell were 6.90 for cells in primary culture, 9.26 for cells of diploid line 5018; 4.50 for cells of pseudodiploid transformed line 4647 and 9.76 for cells of hypotetraploid transformed line 455.

The Alu is immediately flanked by 13-base-pair duplications of the known sequence of the satellite at the site of insertion. These observations support the idea that Ala family members may be moveable elements.

Variations were observed in prealbumin, transferrin, ceruloplasmin, haptoglobin, PGM-II and AK systems in various subspecies of Cercopithecus aethiops. The electrophoretic distance between three forms seems to indicate an intermediary status between populations and subspecies. The reasons for this moderate differentiation are discussed with regard to divergence of ethological characters, as recently studied.

Abstract
After comparison of the chromosomes of 42 species or subspecies belonging to Cercopithecinae, Papioninae and Colobidae, a phylogeny based on the sequence of chromosomal rearrangements is proposed for Cercopithecoidea. From their last common ancestor, which possessed 46 chromosomes, a trifurcation gave 3 branches, very unequal as regards chromosomal rearrangements. One, very short, leads to Papioninae. Another, still poorly known, leads to Colobidae. The last branch leads to a further bifurcation, separating 2 groups of Cercopithecinae, with underwent the most active chromosomal evolution. A tentative to reconcile chromosomal, biochemical and morphological data is presented for Papioninae, for which chromosome study alone is not sufficient to construct a cladogram.

Abstract
Three cloned segments that hybridize to a region of simian virus 40 (SV40) deoxyribonucleic acid including the origin of replication have been isolated from a monkey genomic library. The primary structure of one segment was previously reported (T. McCutchan and M. Singer, Proc. Natl. Acad. Sci. U.S.A. 78:95-99, 1981). We report here the sequences of the other two segments and a comparison of all three. The SV 40-hybridizing region in each segment is limited to several hundred base pairs. All of the segments contain multiple and disconnected sequences homologous to the region of SV40 directly surrounding the viral replication origin. The number and arrangement of the homologous sequences is different in the three segments. However, the segments have the following features in common: (i) each contains multiple copies of the sequence GGGCGGPuPu, which also appears six times near the origin of SV40; (ii) each contains several strong homologies to the central dyad symmetry of SV40; (iii) each contains a long internal repeat, as does the origin region of SV40. The three SV40-hybridizing segments are members of a larger family of genomic sequences that hybridize well to each other, but not necessarily to SV40.

Abstract
By using low-stringency nucleic acid hybridization conditions and specific subgenomic segments of the AKR ecotropic provirus as probes, murine leukemia virus (MuLV)-related sequences were detected in African green monkey (AGM) liver DNA. The MuLV-reactive segments present in restricted AGM DNA ranged from 1.9 kilobases (kb) to greater than 10 kb in size. On the basis of this finding, a 17-kb segment was cloned from a partial EcoRI AGM library in lambda Charon 4A which shared nearly 5 kb of homology with AKR ecotropic MuLV DNA. The MuLV-related sequences detected in restricted preparations of AGM DNA or present in the cloned monkey DNA reacted with probes mapping 2.0 to 7.0 kb from the 5' terminus of the AKR ecotropic provirus. The AGM clone also contained repeated sequences that flanked the MuLV-related segment. Labeled, subgenomic, MuLV-reactive segments of the monkey clone hybridized to multiple restriction fragments of AGM liver DNA, indicating the presence of several copies of the MuLV-related sequences.

Abstract
A new effect of 5-ACR (5-azacytidine), observed in fibroblast or kidney cell cultures is described in the calf (Bos taurus) and in some selected primates (Cebus capucinus, Erythrocebus patas, and Cercopithecus cephus). This cytidine analogue, used at low doses during the last late S phase, prevents the condensation of R-band positive heterochromatin (G-C rich segments). Thus, 5-ACR treatment can be used as a simple method for the detection of G-C rich heterochromatin.

Abstract
The G- and C-banded karyotypes of five species of Cercopithecus are reported. The chromosome numbers are: for C. ascanius katangae 2 n = 66 (XX); for C. petaurista petaurista 2 n = 66 (XY); for C. mona mona 2 n = 68 (XX); for C. pogonias grayi 2 n = 72 (XY) and for C. hamlyni 2 n = 64 (XY). We always found three types of chromosome: metacentric, sub-metacentric and acrocentric. The 'marker chromosomes' typical of the Cercopithecidae are of the last type. The karyotype of C. pogonias grayi shows a characteristic pair of acrocentric autosomes which is again found in the hybrid karyotypes.

Abstract
The karyotype of C. (mona) campbelli campbelli is described after applying various banding techniques. After comparing this karyotype with those of numerous other Cercopithecus species it becomes possible to situate C. (m.) c. campbelli in the phylogeny of the group. A comparison with the human karyotype, after high resolution banding, shows that both species differ by some forty rearrangements, essentially fissions and inversions. A fission of the chromosome homologous to the human no. 10 occurred in this taxon, thus reproducing a chromosome present in Prosimii and Lagomorpha (rabbit), which can be considered as a reverse mutation.

Abstract
We report the molecular cloning of African green monkey genomic DNA segments that include regions of homology to the origin of replication of simian virus 40 (SV40). Three clearly different cloned segments 14 to 17 kilobase pairs (kb) long were isolated from a genomic library in lambda phage. We estimate that each of the three is repeated fewer than four times in the monkey genome. The SV40-like regions represent a small portion of the cloned segments, and these regions cross hybridize only weakly with one another. One of the three segments is described here in detail. Although the entire segment occurs only once or twice in the monkey genome, it contains DNA sequences (other than the SV40-like sequences) that are repeated elsewhere in the genome including in the other two cloned segments. The homology to SV40 is contained within about 300 base pairs of monkey DNA and is limited to the region around the viral replication origin. The nucleotide sequence of the SV40-like region was determined. It contains a large number of short stretches homologous to three specific noncoding domains around the SV40 origin of replication: the 27-base-pair region of dyad symmetry, the first set of (short) repeats that occur just on the late side of the origin, and, further in the late direction, the two 72-base-pair-long repeats. Although these components are grouped in the monkey DNA, as they are in SV40 DNA, their relative juxtaposition is scrambled.

Abstract
Newly evolved, tandemly arrayed, highly repeated DNAs from three primates were compared using Markov-chain and random-simulation approaches. Markov-chain calculations suggested that the repeated DNA sequences derived from the amplification of a progenitor sequence some 55 million years ago. Divergence of the products of this ancestral amplification could have created a library of related DNA sequences from which newly evolved repeated DNA was drawn - by recent amplifications of library members. The ancestral DNA amplification may have provided the genetic flexibility for creating the primate order; more recent amplifications in old-world primates probably led to the present subfamilies. The random-simulation approach verified the idea that repeated DNA evolves nonrandomly. A variable region was identified within the sequence.

Abstract
Primate ribosomal RNA (rRNA) genes have been compared by restriction endonuclease mapping. In all species examined, the restriction map of the reiterated ribosomal DNA is simple (within the limits of detection by hybridization with rRNA) and is consistent with a high degree of homogeneity among the repeats. Within a species, all members have similar rDNA restriction patterns. However, different species of primates have distinctly different rDNA restriction maps; even chimpanzee and man can be discerned by their rDNA restriction patterns. Possible mechanisms for maintenance of homogeneity of the rDNA repeats within a species, while allowing divergence among closely related species, are discussed.

Abstract
The genomes of Old-World, New-World, and prosimian primates contain members of a large class of highly repetitive DNAs that are related to one another and to component alpha DNA of the African green monkey by their sequence homologies and restriction site periodicities. The members of this class of highly repetitive DNAs are termed the alphoid DNAs, after the prototypical member, component alpha of the African green monkey which was the first such DNA to be identified (Maio, 1971) and sequenced (Rosenberg et al., 1978). The alphoid DNAs appear to be uniquely primate sequences.--From the restriction enzyme cleavage patterns and Southern blot hybridizations under different stringency conditions, the alphoid DNAs comprise multiple sequence families exhibiting varying degrees of homology to component alpha DNA. They also share common elements in their restriction site periodicities (172 . n base-pairs), in the long-range organization of their repeating units, and in their banding behavior in CsCl and Cs2SO4 bouyant density gradients, in which they band within the bulk DNA as cryptic repetitive components.--In the three species from the Family Cercopithecidae examined, the alphoid DNAs represent the most abundant, tandemly repetitive sequence components, comprising about 24% of the African green monkey genome and 8 to 10% of the Rhesus monkey and baboon genomes. In restriction digests, the bulk of the alphoid DNAs among the Cercopithecidae appeared quantitatively reduced to a simple series of arithmetic segments based on a 172 base-pair (bp) repeat. In contrast with these simple restriction patterns, complex patterns were observed when human alphoid DNAs were cleaved with restriction enzymes. Detailed analysis revealed that the human genome contains multiple alphoid sequence families which differ from one another both in their repeat sequence organization and in their degree of homology to the African green monkey component alpha DNA.--The finding of alphoid sequences in other Old-World primate families, in a New-World monkey, and in a prosimian primate attests to the antiquity of these sequences in primate evolution and to the sequence conservatism of a large class of mammalian highly repetitive DNA. In addition, the relative conservatism exhibited by these sequences may distinguish the alphoid DNAs from more recently evolved highly repetitive components and satellite DNAs which have a more restricted taxonomical distribution.

Abstract
Genetic variation at 16 protein and enzyme loci in Ceropithecus aethiops and several other primate species has been surveyed, using cellulose acetate microelectrophoresis. Resolution of several standard variant proteins is comparable to that achieved on starch gel or polyacrylamide gel. Although both intraspecific and interspecific variation was observed for some loci, the data generally support the concept that extracellular proteins are more likely to be polymorphic within a species, while intracellular proteins generally vary between species, if at all. These methodologies are particularly appropriate for screening multiple-locus variation in large numbers of samples; their relevance to studies of molecular evolution and evaluation of theories of kin selection is discussed.

Abstract
Somatic cell hybrids produced between cercopithecoid monkey and Chinese hamster cells were used to assay susceptibility to SV40 viral infection in an attempt to define the primate factors that determine permissiveness to viral replication. These cell hybrids, which differed in their primate chromosome complement, were found to differ also in their ability to sustain viral replication. A correlation was found between an elevated SV40 viral replication and the presence of the chromosomes 11 in the rhesus monkey and 12 in the African green monkey which seem to be homologous to human 11. Preliminary studies also showed that the same chromosome seems to be responsible for the ability of the cell hybrids to rescue virus from rodent-transformed cells.
