A Pan-TE Map Reveals the Important Role of Transposable Elements in Gene Expression and Phenotypic Diversity in 2,311 Rapeseed Accessions.

ABSTRACT: Transposable elements (TEs) play an important role in shaping gene transcription regulatory networks and driving genome evolution. However, there is still little understanding for TE polymorphisms at the species level of rapeseed and their impacts on gene expression and phenotypic formation. This study systematically identified 8 268 255 TEs from 14 rapeseed genomes and constructed the first rapeseed pan-TE map and then obtained TE insertion polymorphisms (TIP) in 2311 oilseed rape accessions (Brassica napus). Integrative analysis of transcriptome data suggests TEs modulate transcription by diverse cis-regulatory mechanisms and 67% TEs related to nearby gene promote transcription. TE-GWAS identified 1427 TEs in 80 loci associated with 15 traits. Further multi-omics analysis identified a TE
