Development and use of novel gene technologies to increase biomass yield in the woody perennial Populus spec
Background and Objective
The objective of the work is the generation of qualitatively optimized poplar plants with increased biomass, altered lignin content and optimized plant architecture. This will be achieved by the genetic modification of genomic regulators for tree biomass yield, changes of lignin biosynthesis and alterations of branching patterns.
Biomass production can be increased by genes involved e.g. in vegetative growth capacity, vascular cambium activity, and secondary cell wall formation. The ThünenInstituteofforest genetics is workingwithpreviouslyunknowngenesthat are expressed inwoodas well asinpoplar flowers.
