Induction of early flowering in poplar
Project
Project code: vTI-FG-08-42
Contract period: 01.05.2007
- 31.12.2010
Purpose of research: Applied research
Biosafety studies with transgenic forest plants suffer from the long generation times of trees. To analyze gene technologically induced sterility within a given time frame of two to three years it is desirable to shorten the vegetative phase of the poplars considerably. Hence, the support of the induction of flower formation is very important with transgenic poplars within the scope of the investigations for sterility. A gene technologically approach is tested beside physiological attempts for the production of early-flowering poplar lines with the help of the genes which have caused an early flowering already in other plant species. Up to now all attempts have missed to stimulate flowering in one-year-old to three-year-old poplars by means of physiological attempts (application of growth retardants, demethylation agents and hormones). In contrary, transgenic poplar carrying “early-flowering” genes formed flowers either already some months after the gene technologically change or as three-year-old plants. Different genetic constructs were used for the transformation by poplars.
