The genome sequence of black poplar, Populus nigra subsp. betulifolia L., 1753 (Salicaceae) [version 1; peer review: 1 approved, 2 approved with reservations]

We present a genome assembly from an individual Populus nigra subsp. betulifola (black poplar; Tracheophyta; Malpighiales; Salicaceae). The genome sequence is 413.2 megabases in span. Most of the assembly (99.73%) is scaffolded into 19 chromosomal pseudomolecules. Mitochondrial and plastid genomes were also assembled. Three mitochondrial assemblies have lengths of 281.85, 335.57 and 186.15 kilobases, and the plastid genome has a length of 156.37 kilobases.
