Genome collinearity, telomer and centromere structures in P. ussuriensis and P. trichocarpa genomes. (a) Collinearity between the genomes of P. ussuriensis and P. trichocarpa (gray lines). The red triangles mark the positions of telomere sequence repeats. The black rectangles illustrate the positions of gaps. (b) Structural delineation of P. ussuriensis Chromosome 07 centromere that corresponds to an unfilled gap in P. trichocarpa genome. (c) Structural delineation of P. ussuriensis Chromosome 13 centromere that corresponds to an unfilled gap in the P. trichocarpa genome.
