Description: Poplar hybrids have high light-saturated photosynthetic rates and potential utility as a renewable biofuel, but they lack tolerance to commercially important herbicides that may be needed for successful plantation management. Tolerance to glyphosate (N-(phosphonomethyl)glycine) has been conferred to many plants by Agrobacterium-mediated transfor-mation with the mutant aroA gene, which encodes glyphosate-tolerant 5-enolpyruvylshildmate-3-phosphate (EPSP) synthase (EC 2.5,1.19) (Comai et al. 1985). While foreign DNA has been inserted into the genome of numerous herbaceous species by Agrabacterium-plant DNA transfer systems (Davey et al. 1986; Zambryski 1992), genetic transformation of hybrid poplar has only recently been reported (Fillattiet al. 1987b). Owing to long sexual regeneration times of trees and their large size at maturity, genetic engineering is particularly useful for development of herbicide-tolerant poplar varieties (Nelson and Haissig 1986).
