A research team has successfully assembled a nearly gap-free, telomere-to-telomere (T2T) genome of Populus ussuriensis, filling gaps present in the P. trichocarpa genome. Leveraging long-read sequencing, the team identified and annotated centromere regions in all double haploid (DH) genome chromosomes, providing a first for poplars. With 34,953 protein-coding genes, this genome surpasses P. trichocarpa by 465 genes.
