Research - Past Projects

Annotation: 

The overall goal of the project is to determine the factors responsible for the inefficiently of existing, pre-sowing treatments so that beechnut germination and subsequent emergence of beech germinants can be improved. The results will be used to develop protocols for providing better and more economical use of beechnuts including field emergence and for obtaining sufficient quantities of seedlings for reforestation.

Annotation:

The aim of the project is to evaluate the response of Norway spruce somatic embryos to abiotic stresses. Somatic embryos will be exposed to different desiccation treatments (high temperature and decreased humidity) and to different doses of UV-B radiation. The alterations of activities of polyamine biosynthetic enzymes and contents of polyamines, abscisic acid (a key endogenous messenger in a plant's response to stresses) and the extent of lipid peroxidation will be evaluated in somatic embryos cultured in stress conditions.

Annotation:

The aim of the project was to elucidate the role of proline and polyamines, metabolites with the crucial protective functions, in the stress response of tobacco plants to high temperature and drought.

Characterization of defence response in wild plants and in transgenic plants with modified P5CS gene (P5CSF129A), which codes for the key enzyme of proline biosynthesis, contributed to understanding of the function of these protective elements in plant abiotic stress tolerance.

Annotation:

The obtained results contributed to understanding of the role of polyamines and additional biological mechanisms in optimization of the induction of embryogenic lines and somatic embryo conversion of Hurst ecotype of Norway spruce. New knowledge on the genetic diversity of Hurst ecotype of Norway spruce will be used in reproduction the required genotypes.
