A pangenome-guided manually curated library of transposable elements for Zymoseptoria tritici

OBJECTIVES: High-quality species-specific transposable element (TE) libraries are required for studies to elucidate the evolutionary dynamics of TEs and gain an understanding of their impacts on host genomes. Such high-quality TE resources are severely lacking for species in the fungal kingdom. To facilitate future studies on the putative role of TEs in rapid adaptation observed in the fungal wheat pathogen Zymoseptoria tritici, we produced a manually curated TE library. This was generated by detecting TEs in 19 reference genome assemblies representing the global diversity of the species supplemented by multiple sister species genomes. Improvements over previous TE libraries have been made on TE boundary resolution, detection of ORFs, TE domains, terminal inverted repeats, and class-specific motifs. DATA DESCRIPTION: A TE consensus library for Z. tritici formatted for use with RepeatMasker. This data is relevant to other researchers investigating TE-host evolutionary dynamics in Z. tritici or who are interested in comparative studies of the fungal kingdom. Further, this TE library can be used to improve gene annotation. Finally, this TE library increases the number of manually curated TE datasets, providing resources to further our understanding of TE diversity.
