Segmental duplications of 33-55 kb DNA blocks in the F3'5'H locus on grapevine chr6, delimited by genetic markers VrZag30 and VMC3F12. Dot plot self-comparison shows tandem duplications as linear arrays of dots in the same orientation as the main diagonal, but horizontally or vertically shifted off the main diagonal. The red grid delimits nine duplicate blocks. Cyan ticks indicate the position of 15 F3'5'Hs. The fraction of TEs in a sliding window of 25 kb (red line) and 50 kb (black line) is shown in the graph superimposed onto the dot plot in the gap of the sequence assembly indicated by the orange bar.
