Interpretive Summary: Genome sequences often consist of functional regions that are represented by genes as well as repetitive regions called Transposable Elements (TE) that have the ability to make copies and integrate in the genome. In plant genomes, especially in large plant genomes, they represent a very large fraction of the genomes. TEs play a functional or gene regulatory role in the genome architecture and their characterization is essential to the understanding of plant function and evolution. However, their repetitive nature makes it challenging to characterize them. This benchmarking study offers a comprehensive approach in the characterization and annotation of TEs for reference genomes.

Technical Abstract: Sequencing technology and assembly algorithms have matured to the point that high-quality de novo assembly is possible for large, repetitive genomes. Current assemblies traverse transposable elements (TEs) and provide an opportunity for comprehensive annotation of TEs. Numerous methods exist for annotation of each class of TEs, but their relative performances have not been systematically compared. Moreover, a comprehensive pipeline is needed to produce a non-redundant library of TEs for species lacking this resource to generate whole-genome TE annotations.
