Improvement of The Yield and Quality of Poplar Biomass for the United States Bio Fuels Industry
Hybrid poplar plantations will play a large role in the supply of cellulosic feedstock, in meeting the Nation's 30x30 goals for the renewable transportation fuels industry. The success of the poplar plantation industry will be contingent on elite plant material that has undergone hybridization for improved agronomic characteristics. Hybridization between the cottonwoods and the poplars has been the preferred method of generating elite varieties. We propose to integrate molecular tools into a traditional hybridization program to breed a new class of varieties that are capable of bio-fuels production with improved conversion economics. To accomplish this, we are currently conducting an association genetics study to identify genes controlling cellulose production in black cottonwood, based on single nucleotide polymorphisms (SNP's). We now propose a comparative study with black poplar to complete our understanding of how best to re-design a hybridization program using
molecular markers and bioinformatics. A large black poplar collection will be cloned and established at two contrasting locations in the Pacific Northwest. We will sequence the same lignin and cellulose biosynthetic pathway genes identified in the black cottonwood study to discover new SNPs that can be used in a Phase II association study. The comparative study will advance our understanding of the manner in which reciprocal parental populations should be managed in a marker-assisted breeding program for improved first-generation hybridization for enhanced bio-fuels application.
