Abstract

The choanoflagellates are a ubiquitous group of nanoflagellates and the sister group of Metazoa. Examination of the initial draft version of the first choanoflagellate genome, that of Monosiga brevicollis, reveals the presence of three novel families of long terminal repeat (LTR) retrotransposons and an apparent absence of non-LTR retrotransposons and transposons. One of the newly discovered LTR families falls in the chromovirus clade of the Ty3/gypsy group while the other two families are closely related members of the Ty1/copia group. Examination of EST sequences and nucleotide analyses show that all three families are transcriptionally active and potentially functional within the genome of M. brevicollis.
