Title Gigantic genomes can provide empirical tests of TE dynamics models
Relevance Evolution
Data types Transcriptome or Gene expression
Genome sequencing and assembly
Organisms Ichthyophis bannanicus
Description Transposable elements are a major determinant of eukaryotic genome size. The collective properties of a genomic TE community reveal the history of TE-host evolutionary dynamics and impact present-day host structure and function, from genome to organism levels. In rare cases, TE community-genome size has greatly expanded in animals, associated with increased cell size and altered anatomy and physiology. We characterize the TE landscape of the genome and transcriptome in an amphibian with a giant genome the caecilian Ichthyophis bannanicus. We synthesize previous models integrating TE abundance, diversity, and activity, and we test whether the caecilian data meets model predictions. We propose thorough, consistent characterization of TEs to strengthen future comparative analyses. Such analyses will ultimately reveal whether the divergent TE assemblages found across convergent gigantic genomes reflect fundamental shared features of TE-host genome evolutionary dynamics.
