Role of ABSCISIC ACID.INSENSITIVE3 homologue in abscisic acid signal transduction studied in system of Norway spruce somatic embryogenesis.

Annotation:

We extend the information dealt with the concentration and composition of antioxidants in selected apple varieties from IEB. The research activity of the Station of apple breeding is focused on research of resistance against diseases in apples and on breeding of scab resistant and powdery mildew tolerant apple varieties. Breeding for resistance to these diseases has a high priority throughout the world in view of minimizing the use of chemicals in fruit production.

Annotation:

The aim of the project is to evaluate the relationship between polyamine metabolism and autophagy in plants. Autophagy will be followed in two experimental systems - in tobacco BY-2 cell culture and in coniferous embryogenic cultures. Firstly, the polyamine metabolism will be monitored during induced autophagy, then the process of autophagy will be studied after exogenous application of higher polyamines or endogenous modulation of polyamine synthesis. The obtained results will contribute to understanding of the function of polyamines in plant autophagy.

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.
