Development and annotation of shotgun sequence libraries from New World monkeys

The draft genome sequences of several primates are available, providing insights into evolutionary and anthropological research. However, genomic resources from New World monkeys are conspicuously lacking. To date, the genomes of only two platyrrhine species, the common marmoset and the Bolivian squirrel monkey, have been fully sequenced. This is especially limiting for comparative genomics research, considering that New World monkeys are the most speciose primate group, and platyrrhine genetic diversity is comparable to that of the catarrhines (i.e. apes and Old World monkeys). Here, we present the generation and annotation of numerous sequence reads from the genomes of Spider monkey (Ateles belzebuth), Owl monkey (Aotus lemurinus) and Uakari (Cacajao calvus), representing the three platyrrhine families, Atelidae, Cebidae and Pitheciidae, respectively. These sequencing reads were developed from gDNA shotgun libraries containing over 3000 individual sequences with an average length of 726bps. Of these sequences, 1220 contain <20% repeats, and thus are potentially highly useful phylogenetic markers for other platyrrhine species. Among them, a large number of sequencing reads were found to match unique regions within the human (2462 sequences) and the marmoset (2829 sequences) genomes. In particular, the majority of these sequencing reads are from putatively neutrally evolving intergenic regions. Thus, they are likely to be highly informative for inferring neutral evolutionary patterns and genomic evolution for other New World monkeys.
