Chromosomal distribution of interstitial telomeric sequences in nine neotropical primates (Platyrrhini): possible implications in evolution and phylo…

2016

To localize interstitial telomeric sequences (ITSs) and to test whether their pattern of distribution could be linked to chromosomal evolution, we hybridized telomeric sequence probes (peptide nucleic acid, PNA) on metaphases of New World monkeys: Callithrix argentata, Callithrix jacchus, Cebuella pygmaea, Saguinus oedipus, Saimiri sciureus, Aotus lemurinus griseimembra, Aotus nancymaae (Cebidae), Lagothrix lagotricha (Atelidae) and Callicebus moloch (Pithecidae), characterized by a rapid radiation and a high rate of chromosomal rearrangements. Our analysis of the probe signal localization allowed us to show in all the species analysed, as normally, the telomeric location at the terminal en…

WILLIAMS-BEUREN MAPPING IN CALLITHRIX ARGENTATA, CALLICEBUS CUPREUS AND ALOUATTA CARAYA INDICATES DIFFERENT PATTERNS OF CHROMOSOMAL REARRANGEMENTS IN…

2007

Human chromosome 7 has a complex syntenic origin. It was divided into two segments in both the ancestral primate karyotype and in Platyrrhini. Apparently, a small segment in the ancestral platyrrhine karyotype was associated with HSA5 and the remainder formed a middle-sized submetacentric. We tested the dynamics of platyrrhine chromosomes by hybridizing the locus specific Willams-Beuren probe (7q 11.23, 450 kb) to chromosomes of representative species from the three families of the New World monkeys recently proposed by molecular genomics: Cebidae, Callithrix argentata (bare ear marmoset or silvery marmoset, 2n = 44); Pitheciidae, Callicebus cupreus [red titi monkey, or coppery monkey, 2n =…
