Populus trichocarpa (Black cottonwood) is a fast growing deciduous tree belonging to the willow family (Salicaceae) which is grown for its timber and for fiber products, mainly in North America.

The genus Populus is widely distributed over the northern hemisphere with many species that are economically important. Populus trichocarpa was chosen as the first tree to be sequenced because of the relatively small size of its genome.

The Populus trichocarpa genome has a haploid chromosome number of 19, and with over 400 Mb is nearly four times larger than the genome of Arabidopsis. There are 44,000 protein-coding genes. About 8,000 pairs of duplicated genes are present due to an early genome duplication event.
