Contribution of super-resolution microscopy and image analysis to the study of plant in vitro cultures with the emphasis on somatic embryogenesis of conifers Past Projects

Annotation: 

The aim of the COST Action CA15124 - A new Network of European BioImage Analysts to advance life science imaging (NEUBIAS) is to maximise the outputs of image-based research in life sciences by empowering the international network of bioimage analysis (IA) experts - BIAlysts.

Effect of drought and heat stress on polyamine metabolism and contents of phenolics, auxin and abscisic acid in Norway spruce somatic embryos Past Projects

Annotation:

The aim of the project was to evaluate the alterations in polyamine metabolism and in the levels of hydroxycinnamic acids, flavonoids and stilbenes in the stress response of somatic embryos of Norway spruce to drought and high temperature. The determined contents of abscisic acid and auxin contributed to understanding the abscisic acid-auxin cross-talk in the response to stress. The extent of lipid peroxidation (as indicated by MDA levels) in stressed somatic embryos was also investigated. Histochemical tests for the presence of polyphenolic substances on embryo sections after the exposure of somatic embryos to UV-B completed the biochemical analyses.

Effect of UV-B radiation on polyamine metabolism and accumulation of hydroxycinnamates and flavonoids in Norway spruce Past Projects

Annotation:

The aim of the project was to evaluate the alterations in polyamine biosynthetic enzymes and polyamine contents and the levels of hydroxycinnamic acids and flavonoids after the exposure of embryogenic tissue cultures of Norway spruce to UV-B radiation. Histochemical tests for the presence of polyphenolic substances (with UV-B protecting character) on embryo sections completed the biochemical analyses.

Improvement of pre-sowing treatments for dormant, European beech seeds 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.

Response of Norway spruce somatic embryos to abiotic stresses Past Projects

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.
