Survey of the composition of major repeats in Brassica genomes based on 1 × read mapping. Overall composition of repeats in these three Brassica genomes include centromeric tandem repeats (CentB-1 and CentB-2) (A), and 8 other repetitive elements (B). Repeat abundance in 64 accessions of B. oleracea (Bo-1-44), B. rapa (Br-1-11) and B. napus (Bnp-1-9), including (C) CentB-1 and 2 (D) 5 S and 45 S ribosomal DNA (nrDNA), (E) STRs (F) centromere-specific retrotransposon of Brassica (CRB) and peri-centromeric retrotransposon of B. rapa (PCRBr1a), (G) Ty1/Copia retrotransposon of Brassica (BoCop-1), and CACTA DNA transposon of B. oleracea (BoCACTA).
