Discovery of a new repeat family in the Callithrix jacchus genome.

ABSTRACT: We identified a novel repeat family, termed Platy-1, in the Callithrix jacchus (common marmoset) genome that arose around the time of the divergence of platyrrhines and catarrhines and established itself as a repeat family in New World monkeys (NWMs). A full-length Platy-1 element is ∼100 bp in length, making it the shortest known short interspersed element (SINE) in primates, and harbors features characteristic of non-LTR retrotransposons. We identified 2268 full-length Platy-1 elements across 62 subfamilies in the common marmoset genome. Our subfamily reconstruction and phylogenetic analyses support Platy-1 propagation throughout the evolution of NWMs in the lineage leading to C. jacchus Platy-1 appears to have reached its amplification peak in the common ancestor of current day marmoset
