Use as model species

P. trichocarpa has several qualities making of him a model good of study to include/understand the physiology of the trees.

Its growth is very fast
economic Importance, it is very required by the industrialists
the size of sound Génome

The sequence of the genome was published in 2006. The genome contains 485±10 million pairs of bases distributed on 38 Chromosome S. Environ 45.500 Gène S coding of the Protéine S were identified. This study will make it possible to contribute to work concerning the improvement of the resistance of the poplar to the Pathogène S and Insecte S Phytophage S, the physiology and the genetics of the trees and the formation of wood. It will also contribute to better including/understanding the evolution of the Angiosperme S.
