Genome analysis in trees

Structural and functional analysis of genomes of forest trees

Trees are characterized by a number of specific characteristics which are under genetic control, like longevity and wood formation.

Background and Objective

It is expected that several genes are involved in the mentioned processes. The aim of this task is the isolation and characterization of regulatory and other different gene sequences which are specific for trees. Species of the genus Populus (poplar) will be used for the investigations.

Approach

Poplars are an excepted model system for trees because of their relatively small genome and accessibility to the Agrobacterium transformation system. Following Arabidopsis and rice the genome of Populus has been totally sequenced. These information serve as basis for the planned investigations.

Preliminary Results

The strategy is based on results of earlier work. Here it was shown for the first time that the genetic transformation of poplar using the transposon Ac from maize is feasible. The results show that Ac excises from its original position in the construct and re-integrates somewhere in the genome (transposition). Further it was demonstrated, that transposition of Ac still occurs in six-years old transgenic plants.; ; Following transformation of Ac more than 100 different, independent transgenic aspe
