Syntenic alignments among assembled Salicaceae haplotype genomes and their reference genome of P. alba var. pyramidalis (a), P. euphratica (b), S. chaenomeloides (c), and S. arbutifolia (d). The syntenic regions among haplotype I (left), reference genome (middle) and haplotype II (right) are shown by gray lines. Centromeres are shown as Khaki triangles. Telomeres are shown as black triangles at chromosome ends. Inversions between each haplotype and the reference genome are shown in orange blocks. 5S and 45S rDNA regions are shown as blue and yellow rectangles, respectively. TE density of each chromosome is shown as cyan histograms
